Being scammed; once again!

The latest tricks are very clever!

I’m too confident, and I need to change. My confidence comes from having been scammed a few years ago, and trying now to be very careful.

But scamming is moving forward, technologically speaking, at a great pace.

Thus, I’m including the following article from The Conversation because it offers fantastic tips.

AI is supercharging money scams – here’s what you can do to protect yourself

The phone rings, and it’s your grandson’s shaken voice. There’s been an accident, he says, and he needs money before anyone finds out. Except it isn’t him. It’s software that learned his voice from a clip posted online, run by a stranger working through a list of phone numbers.

For years, warnings about artificial intelligence and cybersecurity have focused on corporate networks and government systems. Those threats are real. But if you follow the money in the FBI’s fraud data, a different picture emerges: Staggering sums are flowing out of household accounts.

In its 2025 annual report, the FBI’s Internet Crime Complaint Center began tracking complaints with an AI connection for the first time. Americans filed more than 22,000 such cases and reported roughly US$893 million in losses. Investment fraud accounted for $632 million of that, and people over 60 accounted for $352 million of the losses.

Those figures include only victims who reported to the FBI, and only cases where AI’s role could be identified. The consulting firm Deloitte projects that the actual hit from AI will be much bigger and help push U.S. fraud losses overall to $40 billion by 2027, up from $12.3 billion in 2023.

I’m a finance professor who studies household finance and how people use AI to make money decisions. And I believe the most consequential AI security story right now isn’t unfolding in server rooms, but at kitchen tables.

Old cons, new machinery

None of these scams are new. What AI changed is the cost and the quality of the cons.

Cloning a voice now takes a few seconds of audio and cheap consumer tools. In one study, listeners were able to identify an AI-generated voice only about 60% of the time. Video is heading the same way. In 2024, a finance employee at the architecture and design firm Arup was tricked into wiring about $25 million to fraudsters after they set up a video meeting “staffed” by deepfakes of the chief financial officer and several colleagues.

Phishing has improved, too. Clumsy wording and odd formatting used to give fraudulent emails away. Language models now write clean, fluent messages and can personalize them at scale using details scraped from social media. Deepfake videos of well-known business figures pitch bogus trading platforms.

The same pressure is visible in business losses. The cyber insurer Resilience reported that more than 85% of the losses in its claims portfolio in the first half of 2026 stemmed from attacks aimed at people rather than systems.

Why careful people fall for it

We’d like to believe that only careless people get taken. Research in behavioral finance says otherwise.

These scams are engineered around fear and urgency: a panicked grandchild, a boss demanding a same-day transfer, an investment window that closes tonight. Stress narrows attention and pushes people toward fast, intuitive judgments at the very moment they need slow, deliberate ones. Fraudsters also strike a pose of authority, whether a CFO’s face or a government agency’s letterhead, because most people defer to it.

Fluency matters as well. My own research examines how the smoothness of AI-generated communication leads people to trust it. A message with no typos, in a voice that sounds exactly right, sails past defenses that a clumsy fake would have tripped.

Nobody plans to make a major financial decision mid-panic. That’s exactly why scammers manufacture the panic.

The quiet version of the attack

AI-enabled theft doesn’t necessarily involve talking to the victim. Stolen personal data sells for a few dollars on dark web markets. Criminals then feed it to automated AI agents that probe bank and fintech systems around the clock, testing credentials and hunting for weak points at a speed no human crew could match. Last fall, the AI company Anthropic disrupted an espionage campaign in which an AI agent performed 80% to 90% of the intrusion work against roughly 30 targets, including financial institutions.

When an attacker gets into a customer account, the takeover can be over in minutes. Instant payment platforms like Zelle, built for speed and convenience, become the getaway car. The money typically moves within minutes, and getting it back is almost impossible.

How to protect you and your loved ones

Banks defend their own wire rooms with procedures, not vigilance. Households can borrow those procedures.

Check by calling back. When you get a suspicious call, hang up and dial a number you already know – like your bank’s fraud hotline – and never one the caller or message supplies. The point is to leave the channel the scammer controls. A cloned voice can’t answer your grandson’s real phone.

Trust and verify. You should agree on a robust family code word for emergencies and treat any request for money that lacks it as fake. Require two people in your household to sign off on any large transfer, so nobody moves serious money alone and under pressure. And build in a delay, such as a self-imposed 24-hour wait, before any big payment. Urgency is the scammer’s tool. Slowness is yours.

Add layers of protection. Protect the accounts themselves, too. Turn on two-factor login for financial accounts, and never share a verification code with someone who contacts you. That code is the second lock on your door, and the only reason a caller wants it is to get in.

You should also switch on your bank’s transaction alerts so a takeover announces itself in minutes, and consider a credit freeze, which is free and blocks thieves from opening new accounts with data bought on the dark web.

Protect older people. With $352 million of reported AI-related losses coming from Americans over 60, conversations with older family members are key. Walk through the callback rule and the code word, and ask their bank or brokerage about adding a trusted contact they can call. It costs nothing, and it gives the institution a way to raise an alarm before the money moves.

If money has already moved, you should call your bank immediately, ask it to attempt a recovery, then report the scam to the Federal Trade Commission.

Where habits end, rules should begin

Good habits raise the cost of every one of these scams, but they can’t do it all. This is where the U.S. regulations have fallen behind the technology.

Federal law is supposed to protect consumers from unauthorized electronic transfers, and regulators have said that a transfer set in motion by a fraudster counts as unauthorized even when the victim was tricked into handing over account credentials.

In practice, though, victims of instant-payment fraud often recover little. Banks frequently classify losses as “authorized” when a customer was deceived into approving the payment, and even obvious victims of such takeovers can face long fights over reimbursement.

For example, the Consumer Financial Protection Bureau sued Zelle’s operator and three of the country’s largest banks over their response to alleged fraud in late 2024, then dropped the case in March 2025. New York’s attorney general has since filed her own lawsuit, which a judge allowed to proceed in July. Zelle’s operator denies the allegations and says it will appeal.

The U.K. has taken a different path. Since late 2024, U.K. banks have been required to reimburse most scam victims up to £85,000, roughly $115,000, with the cost split between the sending and receiving institutions. The logic is that banks are best equipped to fight fraud, since they run security teams and networkwide analytics that can spot suspicious patterns across millions of transactions. What they had lacked was a strong financial reason to deploy them fully, and the reimbursement rule supplied it.

The regulator’s own dashboard shows that 88% of the money lost to eligible scams has been returned to victims since the rules took effect. More telling: An independent evaluation found that scam losses fell by roughly a fifth in the rule’s first year. That shows that when banks bear the losses, they find ways to prevent them.

I believe American regulators and Congress should study that model closely. When payments are instant and irreversible, the risk cannot rest almost entirely on the customer, who is the least-equipped party in the chain.

The excellent book by Jared Huffman

It is called NO PROPHETS.

Over last weekend I finished reading Jared Huffman’s book. To say is was good would be an understatement. It was excellent.

I will print the last paragraph of the last chapter.

CONCLUSION

We don’t need to agree on everything, but right now we must come together as fellow Americans who agree on the most important thing: Our beleaguered democracy remains the best system of government the world has ever seen, and it belongs to all of us. Let us be worthy of it by confronting the myths, defending the facts, and honouring the Enlightenment inheritance that made pluralistic democracy possible. And as we do, let us remember Thomas Paine’s words that echo across the centuries: “The mind once enlightened cannot again become dark.” (My emboldening.)

Life Beyond Planet Earth

Yet more stories.

It seems as though many articles are exploring life beyond Earth at the moment.

Here is an article from The Conversation.

Have a read.

Many space missions are searching for life beyond Earth – but are we prepared for the fallout if they succeed?

Microbes from space have fueled the plots of science fiction mainstays like “Project Hail Mary” and “The Andromeda Strain.” But with more space missions launching each year, finding extraterrestrial life in a microbial form is becoming more plausible. What will the response be back here on Earth if – or when – scientists discover extraterrestrial microbes? Will the international policy and security communities be prepared for the fallout?

When you hear about extraterrestrial life, your mind may go to intelligent life, like the kind present in a lot of Hollywood science fiction. But even the confirmation of microbial life that originated somewhere other than on Earth – which is much more likely – would be a paradigm-shifting event. Thinking about what these consequences might look like early on can help nations and the international community prepare.

Our team is interested in this question. We’re made up of a full professor of international affairs, who earned a Ph.D. in chemistry, and whose expertise is on how emerging science and technologies could affect global conflict and cooperation, as well as an emerging scholar in space policy and security and an expert on social and political implications of frontier technologies, such as AI, space, quantum and energy sources.

Multiple Mars landers have identified large amounts of frozen and liquid water, essential for life, on the red planet. Samples retrieved by Japan’s Hayabusa2 spacecraft from a near-Earth asteroid revealed the presence of uracil, part of RNA, which is a building block of life. Uncrewed space probes like NASA’s Europa Clipper and the European Space Agency’s Jupiter Icy Moons Explorer are on their way to conduct detailed reconnaissance of the planet’s moons and to investigate whether they have conditions suitable for life. https://www.youtube.com/embed/3HN_zx4JJfM?wmode=transparent&start=0 Scientists are searching for life in space using what they know about life on Earth. But what will happen if or when they find something?

Along with data from the James Webb Space Telescope and future missions targeting Saturn’s icy moon Enceladus, the likelihood of discovering extraterrestrial microbial life has increased substantially.

A governance challenge

The discovery of microbial life would expose significant gaps in international governance related to space.

While there are some existing international agreements, including the Outer Space Treaty, that provide space law guidelines, these are ill-equipped to address the complexities posed by extraterrestrial biology.

The Outer Space Treaty, established in 1967, dictates that countries should use outer space peacefully. It also states that no single nation may claim ownership or exert sovereignty over parts of outer space or celestial bodies such as the Moon.

However, it doesn’t have much to say about who can own extraterrestrial organisms or what to do about biosecurity risks. It doesn’t have direction for who can use, preserve or destroy living things, such as bacteria or fungi, that may be discovered in space.

Historical analogies and future pathways

While people have yet to discover extraterrestrial life of any kind, there are some major geopolitical events that can help researchers understand what the consequences might look like.

While the space race of the 1950s and ’60s led to exploration of the Moon, it was driven by a Cold War power struggle between two nations back on Earth. Instead of coming together to explore space, both countries experienced a renewed sense of nationalism. They used the new discoveries that came from the space race to invest in their military capabilities.

On the other hand, researchers can look at how states respond to asteroid threats. Since an asteroid could pose a truly existential threat from space, preventing the worst-case scenario requires cooperation and thinking ahead.

Astronomers have built a global, collaborative network to monitor for and sound the alarm about any potential threats. This network has shown that nations can put aside terrestrial rivalries to work together if they perceive something from space as a truly existential threat.

The International Space Station is another example showing how nations that are competing great powers on Earth work together to cooperate in space. Countries have collaborated to solve issues on the International Space Station that have specific, short-term and clearly identified goals.

These examples show a range of possible reactions to the discovery of space microbes. The situation could renew space races between competing countries and lead to militarization, or it could create unprecedented cooperation.

Potential outcomes

We’ve identified three main possible outcomes to the discovery of microbial extraterrestrial life.

First, there’s a cooperative outcome, reminiscent of the asteroid threat network or the International Space Station. Here, nations collaborate to regulate research, share data, protect the planet or advance specific interests they share.

This pathway isn’t inherently benign or malignant. It could entail expanding the roles of international organizations or creating new legal instruments.

Second there’s a competitive outcome, characterized by strategic rivalry between countries. Like in the space race, nations could fight to be technologically superior. They might try to monopolize access to the extraterrestrial microbes or to leverage biological discoveries from the microbes for their own economic or military advantage.

Scientific breakthroughs derived from extraterrestrial organisms could lead to innovations in medicine, agriculture, energy and beyond. However, the organisms could also be weaponized, intentionally or otherwise, which would amplify biosecurity risks. In this sense, the discovery of microbial life could create a new form of technological competition, one that merges space exploration with biological research and development.

The increasing role of private companies, such as SpaceX, complicates this dynamic. These companies receive contracts from the government, blurring the lines between commercial civilian and strategic activities.

For example, around 60% of all satellites currently orbiting the Earth belong to SpaceX’s Starlink subsidiary. The company can – and has – chosen to block access selectively, in alignment with its political priorities. When commercial interests and national priorities diverge, who has access versus who is denied access can be uncertain.

Research around biopiracy may come into play. Biopiracy is a term that applies to two primary issues: the patenting of indigenous knowledge or the patenting of natural resources, such as microbes, for profit. The Budapest Treaty prohibits claiming ownership of a naturally occurring microbe on Earth, but there’s no equivalent for microbes in space.

Third is an isolationist outcome, in which states could sever their involvement in international cooperation due to biosecurity concerns or political distrust. The potential for unknown biological risks, however minimal, could trigger precautionary restrictions on data sharing, which limits international collaboration.

Countries may lose or gain allies as they grapple with whether the microbe could cause harm to humans or the environment, or be developed into a biological weapon.

Emerging technologies will also shape these outcomes. Artificial intelligence and machine learning are already integral to scientific research. Scientists use them to process astronomical data and identify potential biosignatures. Nanotechnology and advances in the life sciences and engineering could allow researchers to study, modify or exploit extraterrestrial microbes, if they’re given access to them.

Countries will have to prepare not only for the scientific implications of discovery but also for its societal and political reverberations. The politicization of scientific discoveries from the microbes could complicate or change how countries respond domestically and at the international scale. Misinformation about the microbes could shape policy and public response.

Preparing for the unprecedented

The discovery of extraterrestrial microbial life would not merely mark a scientific milestone. It would be a geopolitical event.

Rather than attempting to predict a singular outcome, policymakers could adopt scenario-based planning approaches in the meantime to anticipate and prepare for a range of possibilities. In these approaches, participants explore multiple futures through structured activities similar to professional or military wargaming or path games, in which they explore multiple outcomes systematically to test strategies, to plan and to analyze potential outcomes under realistic uncertainty.

In our view, the question is not whether humanity will discover life beyond Earth, but whether it is prepared for the consequences when it does.

It states that the discovery of extraterrestrial life would be a ‘geopolitical event’.

I should say so. I would expect the news worldwide would be focussed on this happening!

These academics mentioned above are, I presume, not the only scientists engaged in this.

It would be a fabulous discovery, and I wonder if it will happen before I die!

RELATIVITY FASTER THAN LIGHT

FTL FROM REDUCING THE DOMAIN OF DEFINITION OF THE LORENTZ TRANSFORMATION

Abstract: Quantum Entanglement has been experimentally demonstrated with utmost certainty to go Faster Than Light, FTL. FTL is NOT signalling (yet!) However, the two notions are extremely close. Special Relativity is conventionally said to exclude Faster-Than-Light signaling because Lorentz transformations can reverse the temporal order of spacelike-separated events. We readjust that notion to make it Entanglement and FTL signaling compatible. 

For an explicit FTL signal with (u=2c), a perfectly ordinary Lorentz transformation indeed assigns a negative reception time in a sufficiently rapidly moving inertial frame.
But this does not demonstrate that physical time travel occurs; it demonstrates that coordinate-time ordering is frame-dependent for spacelike intervals.

The essay argues that the real assumption requiring examination is not the mathematics of the Lorentz transformation, but its unrestricted physical interpretation.
If FTL influences exist, they need not be required to possess the same relativistic transformation properties as ordinary subluminal processes (and they should not as they potentially come from completely different physics)..

The proposed solution is to introduce a preferred Cosmic Manifest Frame (CMF), identified approximately by the Cosmological Microwave Background, CMB, in which FTL propagation and causal ordering are physically defined.
Other inertial frames may assign negative coordinate times to the same FTL process, but those coordinates do not represent reversed physical causality.
Lorentz symmetry is thereby retained as an effective symmetry for domains where it has been experimentally validated, and theoretically deduced, while it is denied fundamental universality.
SQPR adopts precisely such a preferred causal structure, with nonlocal quantum influences propagating at a finite superluminal speed such as TAU (>>>>> c).
The proposal thus attempts to separate the mathematical freedom of spacetime coordinates from the physical ordering of causes and effects.

***

We consider first a concrete numerical example of a specific superluminal speed to make the conventional argument found in Special Relativity textbooks (which we think is erroneous) completely explicit.

The standard argument against Faster Than Light SIGNALING goes as follows:

“Given Special Relativity, SR, if you allow faster‑than‑light signaling, then the Lorentz transformation between inertial frames implies that some observers will see the signal arrive before it is sent. With two such FTL signals, you can construct a closed causal loop, i.e. a form of ‘time travel’ that violates causality.” 

We will show that the “closed causal loop” construction is superfluous to make this (erroneous) argument work. The traditional argument can be made more compact, no need for a loop. This irony is significant, because the existence of a sharper (erroneous) argument against FTL from SR shows that the physicists who pretend to have demonstrated that FTL is impossible from SR have not bothered to find the sharpest argument, possibly indicating that they find the subject unappetizing… Or could it be that they were afraid to be cut by the sharpness of the argument, because, as it turns out, the argument doesn’t even need a causal loop? … It’s that basic…

First let’s give a concrete example. Let the Faster than Light (FTL) signal speed be u = 2c. And let the speed of S’ relative to S be .6c. And the separation L be two light second (twice Earth-Moon). Computation shows that, BLINDLY using the Lorentz transformation, the FTL signal is received in S’ at MINUS .25 second. In other words, time travel.

We argue that this is absurd, and caused by a misuse of the Lorentz transformation by overextending its domain of definition over the spacelike subset of Poincaré spacetime. (Poincaré discovered and used Poincaré spacetime and its metric months or years before those who plagiarized him. In particular Poincaré found the full Lorentz Transformation, LT, using the most general argument; this is important because, in spite of his success using it, clearly Poincaré took Poincaré spacetime with a grain of salt; the present essay explains a plausible reason why; there is another; later, following Poincaré once again, Einstein confessed he didn’t like Poincaré spacetime… Make no mistake: Poincaré’s argument about getting LT from Poincaré spacetime was entirely mathematically correct; what was not done is the physical restriction we undertake below).

Recapitulation in the general case:

We set the frame S and S’ such that their space and time origin coincide x = x’ = t = t’ = 0. That’s event A. Event B is at (L,T) in S, such that L/T = u, superluminal: u > c.

What is the time of B in S’? T’(B) is: (T – v L/cc)γ 

If the signal is FTL, L> cTL. Then there exists some subluminal v high enough such that:

(T− vL/cc) < 0…. Thus t’(B) < 0.

In other words the FTL signal is received at a negative time in S’ … thus before it is sent. 

This is my sharper version of the erroneous argument many physicists have made against FTL.

***

GRAND RETURN OF ABSOLUTE SPACE:

Solution to the riddle of the Lorentz Transformation creating events which have not happened yet: Reject the claim that all inertial frames are equivalent  In other words, as observed in Physical Reality, I mean the cosmos out there, there is a preferred frame in the universe, the one in which the CMB is at rest. (Mach and Newton would opine that this absolute space gives us some hope of explaining inertia. Einstein developed General Relativity in the hope of explaining inertia… He completely failed in that hope, but then we got GPS from GR…)

So postulate a special frame in which FTL is defined and causality is enforced. This is the path of SQPR.

In other frames, you might get “backwards in time” coordinates, but you declare that only the preferred frame’s ordering is physically meaningful.

This does not even abandon standard Special Relativity formally, and certainly not in practice (all the usual formulas are still effective, say for GPS, but one cannot extend the domain of the Lorentz Transformation over the space-like domain). SR has no difficulty representing spacelike intervals. 

What we reject formally is the additional assumption that an FTLphysical influence must transform exactly like an ordinary subluminal signal, with every inertial observer’s time coordinate having equal causal status. 

The Lorentz transformation is mathematically valid on spacetime, but its physical interpretation as a symmetry of every possible causal process need not be valid. Clearly when Poincaré published on June 5, 1905, the Lorentz Transformation as a rotation of Poincaré spacetime, he could not have guessed the EPR argument of 1935 of the demonstration of FTL by Aspect in 1982 (the latter proving that there are causal processes which are not confined by the speed of light; this outside of the domain of the Lorentz Transformation).

***

We can send (not yet controlled) information faster than light (Bell style experiments). Yes the orientation of the device at A has a real physical effect at B, even if the interval AB is spacelike. That has been amply proven theoretically and experimentally. 

We do not reject Poincaré spacetime… After all, it’s the geometrodynamics of light in the first approximation! But it’s just a first approximation; by the way, that seems to have been the point of view of his creator Henri Poincaré, that’s why he talked about the “ether” so much… Similarly Einstein admitted that, in General Relativity, the speed of light varies… The “ether” was a placeholder concept for the sort of hyperspace in which Physical Reality is embedded and that yours truly advocates for…

There are very deep math reasons for this; the math was not yet developed at the time but Poincaré, the world’s greatest topologist then, may have guessed them..

Instead we posit a preferred frame, the CMF, Cosmic Manifest Frame, as given by the CMB, the Cosmic Microwave Background. Call CMF by the letter S (for Stationary).

  • Causality is fundamentally defined.
  • FTL influences propagate with some speed u>c. In the case of SQPR one cosmic quantum collapse/entanglement speed is hypothesized: TAU. 
  • The Lorentz transformation is an effective symmetry only for certain classes of phenomena (e.g. electromagnetism), not a fundamental symmetry of all physics…. Just like light is not all of physics, and sure has little to say about the QUANTUM ENTANGLEMENT machinery it is subjected to (see Aspect Nobel Prize winning FTL experiments). 

This is exactly the loophole that avoids the “FTL ⇒ time travel” argument.

By the way, this restriction of the Lorentz Transformation proposed here will no doubt do wonders to help avoiding causal time like loops around Black Holes…

As we are into grandiose semi poetic evocations, let’s go all the way. I have an entanglement-clock argument: which questions the elevation of coordinate time to fundamental physical time. In the present essay, I similarly question the elevation of Lorentz-frame equivalence to a universal causal principle.

That gives the essay a much deeper unifying thesis: coordinate transformations need not dictate physical causality. (Ironically that idea is nothing new: it led to the creation of Special and General Relativity; what’s new is to push it beyond the old epistemological frontiers, taking FTL and Entanglement seriously…)

Just because this entire post is beyond me, it does not mean that I should not publish it. Because there will be others, one hopes, that will understand the science and the mathematics. And the idea that ‘faster than light’ does exist is incredible.

That wildfire smoke

Where it has come from can make a real difference.

Previous to this week, I hadn’t really thought of wildfire smoke other than it being a nuisance, so long as it did not get too close to home.

However, a recent article on The Conversation changed my understanding, and I bet there are many others out there that will feel the same way as I do.

From flames to haze, wildfire smoke transforms as it travels, and it can harm your health in different ways

As wildfire smoke plumes travel thousands of miles, sunlight and atmospheric chemistry bleach their color, strip away their campfire aroma and add them to the mix of urban smog.

Smoky skies plagued the East Coast and Midwest again in summer 2026, as wildfires hundreds of miles away forced people to cancel sports practices and run air conditioners around the clock.

Living in the western U.S., I am no stranger to this scene. Wildfires and the thick smoke they produce have become a fixture of summer life here. I also study wildfire smoke as an atmospheric chemist, in particular how the smoke evolves as it moves downwind from the flames to the communities where people breathe it.

To understand what’s in the smoke you might be breathing, you have to look at where it’s been.

A North America map shows how wildfire smoke spreads far from its origin, and stays dense for hundreds of miles.
Wildfire smoke is often too high in the atmosphere to be noticed, but when atmospheric conditions bring it close to the ground, people are left breathing unhealthy particles. Joshua Stevens/NASA Earth Observatory

When a forest burns, the wildfire emits large amounts of fine particulate matter, or PM2.5, along with nitrogen oxides and volatile organic compounds, or VOCs. The compounds and particles emitted by wildfires can harm human health, including the lungs, heart and organs, and include known carcinogens.

How this potent mix of pollutants transforms over time and distance is a complex puzzle. At the NOAA Chemical Sciences Laboratory, our team tracks this behavior, from studying controlled fuel burns in the lab to flying research aircraft through wildfire smoke plumes. Understanding how wildfire smoke ages is essential for predicting its impacts on human health.

It all starts at the flame

The story of smoke begins with how the wildfire burns. High temperature wildfires behave very differently from cool, smoldering wildfires.

Hot, intense flames produce nitrogen oxides, which can harm a person’s respiratory system and contribute to the formation of secondary pollutants and reactive carbon compounds like aromatic hydrocarbons, which can increase the risk of certain cancers with long-term exposure. They also emit smaller amounts of nitrous acid, hydrogen cyanide and isocyanic acid, all of which can be toxic to humans.

In contrast, lower-temperature smoldering wildfires release a different mix of compounds, but it is still enriched with toxic aromatic oxygenates and ammonia, which can irritate the respiratory system. This isn’t to say that these wildfire emissions are safer for human health, but rather that burning conditions dictate the chemical makeup of the smoke and its subsequent chemical fate.

Wildfires are rarely just one or the other; they are dynamic mixtures that shift throughout the day as air temperatures rise, humidity drops or evening thunderstorms roll in.

Once smoke leaves the flames, three main factors govern its journey: wind speed, atmospheric temperature and sunlight.

Think of a campfire. If you are sitting in the wrong spot, the prevailing wind blows smoke directly in your face. This horizontal movement is called advection. Small fires often don’t generate enough heat to loft their smoke high, meaning you can smell your neighbor’s campfire.

However, massive wildfires generate immense heat and powerful upward winds. This buoyancy acts like an elevator, lifting the smoke plume out of the planetary boundary layer and injecting it into the free troposphere, roughly 1.2 miles (2 kilometers) above the ground. Up there, high-altitude winds take over, transporting the smoke thousands of miles across the continent.

On occasion, wildfire plumes can generate their own weather, making smoke-laden pyrocumulonimbus clouds, which can inject large amounts of particles into the stratosphere.

How sunlight ‘ages’ the smoke

As smoke travels, it undergoes rapid physical and chemical changes.

First, the plume dilutes as cleaner background air mixes into it. Close to the fire, the smoke is dense and opaque. As it moves downwind, it spreads out and grows more diffuse.

Second, intense sunlight acts as a chemical engine. Solar ultraviolet photons break apart bonds in molecules, creating radicals, which oxidize VOCs. Nitrogen oxides play a key role in driving this chemistry.

Within just hours of being emitted, this mixture reacts to form ground-level ozone, which can irritate the lungs and is a key component of smog.

If smoke is lofted high, into cold free tropospheric air, the chemical aging process can temporarily freeze. The smoke can remain chemically fresh until the air parcel sinks closer to the surface, below about 1.25 miles (2 kilometers), where warmer temperatures can restart the chemical reactions.

When an aging smoke plume passes over a major city, it can mix with urban pollution, such as car exhaust. This interaction can rekindle chemical reactions, creating additional local ozone on top of the fine particulate matter emitted from the fire.

Why distant smoke smells and looks different

Have you ever noticed that long-distance wildfire smoke doesn’t smell like a campfire? There is a chemical reason for that.

The specific compounds responsible for the classic smoky aroma of a campfire – phenolic compounds like guaiacol and syringol – are highly reactive. Sunlight and the associated chemistry destroy them in a matter of hours. By the time the smoke has traveled across several states, the smoky smell is completely gone.

Sunlight also alters the color of the smoke through chemical bleaching of aerosols. Fresh smoke contains dark brown and black carbon particles that absorb light. Over several days of exposure to sunlight and oxidants, chemical reactions break down these dark compounds.

The result?

Dark, light-absorbing particles turn into light-scattering particles, transforming dark, dense plumes into the milky white haze seen drifting across the eastern skies. These particles efficiently scatter the blue and green light while letting red and orange wavelengths pass through, creating the uncanny feeling of an all-day sunset.

The wildfire smoke inhaled hundreds of miles downwind is chemically distinct from the smoke that left the flames, but it remains a serious health threat and an area of active research. Consequently, smoke transport and its associated atmospheric chemistry represent a major North American air quality issue, one projected to intensify in the coming years.

As you can see from the second image, the map of wildfire smoke, here in Oregon there has been substantial smoke, albeit because we live to the west of the Cascades, we have not been directly affected.

However, the summer of 2027 is predicted to be an even drier period than this year, and the potential for wildfires and the associated smoke is a problem that is not going away.

George Monbiot’s wake-up call!

We are losing our fundamental rights.

I follow George Monbiot, and have had his permission for some time to republish his articles.

I was born in November, 1944, some six months before the end of WWII. Over all these years, I have read countless essays and articles about the state of countries, and the world.

However, George’s latest article is the most serious reflection on the state of things, effected by the rich and powerful, that I have ever read. I’m sure I speak for millions of other people.

Our 1933 Moment

Posted on the 4th August 2026

At astonishing speed, around the world, fundamental rights are being cancelled at the behest of oligarchs and corporations.

By George Monbiot, published in the Guardian  31st July 2026

No more resistance in the US. The era of human rights is over, and dissent is once more forbidden. This is what certain billionaires and their concierges want, and this is the model they’re also seeking to project across the world. If we fail to resist, if our new prime minister is as weak and suggestible as the last one, this is what we will get. In fact, we are halfway there already.

Why? Because successive governments in the UK have succumbed to a global campaign to cancel our fundamental freedoms, a campaign led by oligarchs and corporations, the media they own and the junktanks they fund. A campaign that has become definitional for the second Trump presidency.

At a global summit convened by the US government earlier this month, the Trump administration officials Marco Rubio, Stephen Miller and Scott Bessent explained that they were redirecting counterterrorism efforts away from Islamic jihadism and towards “the political left”. Most of the examples they cited to justify this shift were more than 30 years old. Several times they had to dig down to the 1970s to find a sufficiently menacing threat. You could hear the barrel being scraped.

Without producing a shred of evidence, Rubio, the secretary of state, claimed that the Cuban government is “inextricably linked to the far-left groups and movements across and beyond the west”. The following week, his department sought to justify this claim with a report containing a long list of leftwing legislators, journalists and activists that attempted to link them to Cuba in ways that ranged from the tenuous to the hilarious. This is a well-honed tactic, used prolifically by the Nazis among others: they claimed dissenters, by definition, were part of an international communist conspiracy. They insisted, as Rubio did, that “it is time to crush this evil for ever”.

That wasn’t the only crude reminder. Miller, Donald Trump’s deputy chief of staff, maintained that when you see antifascist protests, “not one of the people that is demonstrating looks like a normal person. Not one looks normal. They’re all deformed in some way – in their appearance, in their dress, in their mannerism … their outer appearance becomes a manifestation of their inner hatred.” I’m just surprised he didn’t say “untermenschen”. The US government, by contrast, promotes “normal, healthy, ordered living”.

But what hit me even harder was Miller’s attack on “jury nullification”: jurors acquitting people who, he said, were “obviously guilty”. Shutting down this possibility has been an aim of illiberal governments and conservative judges around the world. We saw it in the UK in the prosecution of Trudi Warner and others for holding signs that state an ancient principle in English law: “Jurors have an absolute right to acquit a defendant according to their conscience.”

We see it in the astonishing prosecution, being pursued at the moment, of Rajiv Menon KC, who reminded jurors of this right at the trial of the Palestine Action campaigners he was defending. He became, as a result, the first lawyer in English history to be charged with contempt of court for a closing speech. If convicted, he faces up to two years’ imprisonment and will be struck off. Prosecuting lawyers for defending their dissident clients is more or less the definition of authoritarianism.

We also saw it in the assault Keir Starmer launched on jury trials as a whole, greatly curtailing, without any coherent justification, our strongest defence against injustice.

Starmer was a weak man, without a clear vision of his own, who was rolled by any powerful state or corporate lobby. He was no match for a well-funded and highly effective international campaign. A network of groups such as the American Legislative Exchange Council, funded by corporations and billionaires, has been producing “model legislation”. The groups test these laws in sympathetic jurisdictions. If they are found to work, they then press for their adoption elsewhere. The result is a sustained assault on our rights to protest, to political equality and to a habitable planet.

The globalisation of this attack on our fundamental rights is a key conservative aim. As capital operates everywhere, so should its ability to crush our objections. The long series of vicious anti-protest laws in the UK is an outcome of sustained lobbying by junktanks, the media and other governments. The result is a country that now keeps hundreds of political prisoners, a country in which you can get six months in jail for marching slowly down the street.

These oppressive laws have culminated – so far – in an act of parliament passed in April that enables the police to shut down any protest they deem to have a “cumulative” impact on the community. The only protests that have ever succeeded are those with a cumulative impact. Protest is acceptable as long as it’s useless. Let the people have their say, but only if we can’t hear them.

The new laws have been accompanied by that age-old trick, traditionally associated with fascist regimes, of smearing leftwing dissidents as terrorists. As the rights group Liberty has pointed out, the definition of terrorism here has greatly expanded, to incorporate tactics formerly regarded as civil protest. This is what enabled Starmer’s government to ban Palestine Action.

The judge who referred Menon for contempt, Mr Justice Johnson, was also the first – at the same trial – to use the extraordinary powers quietly inserted by the Conservatives into the Sentencing Act 2020. These enable someone tried for one crime to be sentenced for another. The four Palestine Action protesters were convicted of ordinary crimes. But, without informing the jury, Johnson marked the case as having a “terrorist connection”. He then sentenced them for terrorist offences, which means much more prison time.

Already, his example has been followed by another judge: a different group of pro-Palestine protesters, who sprayed red paint and broke some windows of a branch of Barclays Bank, are about to be sentenced as terrorists, though neither they nor the jurors were told of this possibility during their trial for criminal damage. This means, of course, that they were unable to defend themselves against this far more serious charge.

Nothing is safe from the billionaire assault on humanity. None of our rights, however ancient and familiar, are impregnable. Fight for them now or lose them, perhaps for ever.

Your pet’s milestones.

Another article from Penny.

These milestones would not be in place without us owners. For all pets, cats and dogs and birds, and more, do not think in terms of milestones.

However, our pets are so special to us humans that we create these special moments.

How to Capture and Cherish Your Pet’s Special Milestones

For pet owners watching their companions move through different pet life stages, the days can blur faster than expected. The core tension is real: documenting pet milestones sounds meaningful, but pet memory keeping often slips between busy routines and the pressure to make every photo, note, or keepsake “perfect.” Yet the emotional value of pet moments shows up later, when a goofy habit fades or a first-time victory becomes a distant detail. Preserving pet memories turns everyday life into something that can be held onto.

Quick Summary: Pet Milestones Made Easy

  • Start by choosing a few essential pet milestones you want to remember and track.
  • Capture special moments with photos to preserve milestones in a simple, shareable way.
  • Record quick notes alongside memories to add context and meaning over time.
  • Keep small keepsakes from key moments to create lasting, tangible reminders.

Rescue Blurry Milestone Photos With AI Upscaling

Once you’ve decided which “firsts” you want to keep, the next challenge is making sure the photos look as special as the moment felt. AI image optimization tools can help rescue milestone shots that are dim, soft, or low-resolution by automatically improving lighting, sharpening tiny details (like whiskers and fur texture), reducing blur, and enriching colors for a clearer, more vibrant result. That’s especially helpful for those quick, imperfect captures, your pet’s first day home, first park trip, or first birthday, where you don’t get a redo.

An AI image upscaler takes this a step further by enhancing resolution and clarity so you can enlarge a favorite photo while still preserving detail and visual quality. If you want a simple starting point, the Adobe Firefly AI image upscaler feature is one way to create a print-ready version for albums, frames, and long-term saving. With your milestone images looking crisp, you’re ready to follow a straightforward process for documenting your pet’s life without overwhelm.

Build a Simple System to Capture Pet Milestones

This process helps you reliably capture your pet’s big moments and keep the memories easy to find later. It matters because when life gets busy, a simple system beats a perfect plan you never use.

  1. Pick your “must-capture” milestones
    Start with 6 to 10 moments you truly care about, such as first day home, first vet visit, first groom, first trip, and adoption anniversary. Keeping the list short prevents decision fatigue and makes it more likely you will follow through. Add one flexible category like “unexpected win” for funny or sweet surprises.
  2. Set up a one-glance reminder you will actually see
    Put key dates into a personalized calendar so upcoming milestones do not sneak past you. A year-round visual reminder also prompts you to capture seasonal favorites like the first sweater day or first beach trip. Choose one place to track dates, not three.
  3. Create a repeatable photo checklist for “firsts”
    When the moment happens, take three quick shots: a wide scene (context), a close-up (face details), and one with you or a family member (connection). Use natural window light when possible and keep the background simple so your pet stays the focus. This tiny checklist makes even rushed photos feel intentional.
  4. Log the memory and file it immediately
    Right after you take the photos, write one sentence in your notes app: what happened, the date, and one detail you do not want to forget. Then save everything into a single folder using the same naming style each time, such as “2026-07 First Park Trip.” This keeps your camera roll from becoming a scavenger hunt.
  5. Organize health records alongside the memories
    Choose one home for pet documents, such as a binder with tabs or a digital folder with subfolders for vaccines, meds, and receipts. After each visit, add a quick summary like weight, any new instructions, and the next due date. Pairing health notes with milestone photos gives you a fuller picture of your pet’s life story.

Habits That Make Pet Milestones Easy to Keep

Milestones are easiest to cherish when they become routine, not a once in a while project. These habits keep memory keeping light, repeatable, and realistic, even on busy weeks.

One-Minute Memory Note

  • What it is: Write one sentence: date, what happened, and one detail you loved.
  • How often: After any notable moment.
  • Why it helps: Tiny notes make photos meaningful years later.

Sunday “Sort and Label” Reset

  • What it is: Spend five minutes naming new photos and moving them into your pet folder.
  • How often: Weekly.
  • Why it helps: You avoid a giant camera roll backlog.

Window-Light Photo Habit

  • What it is: Take pictures near soft diffused lighting instead of harsh overhead bulbs.
  • How often: Whenever you photograph.
  • Why it helps: Your pet looks calmer and clearer in a less stressful light.

Monthly Keepsake Check-In

  • What it is: Add one favorite photo and one note to a monthly album page.
  • How often: Monthly.
  • Why it helps: A median of 59 days can turn effort into autopilot.

Start Small to Preserve Your Pet’s Milestones for Life

It’s easy to love your pet fiercely and still let the little moments slip by in the rush of everyday life. A gentle, routine-first mindset, tiny check-ins instead of big projects, keeps pet memory simple and sustainable while reflecting on the pet-owner bond. Over time, those small captures become a clear, comforting record of pet growth and milestones, valuing your pet’s life journey without pressure. Celebrate one tiny milestone today, and your pet’s story will take care of itself. Pick one small next step now: label a favorite photo, jot a two-line note, or record a quick moment. That’s how motivating pet milestone preservation turns into a steadier sense of connection that lasts well beyond the day.

Once again Penny has written about looking after our pets, and she has set out some brilliant habits. I particularly like the monthly keepsake check-in, and starting small so that you do not end up not doing anything at all.

Our pets are so precious to us.

Presidential transport

An article about Air Force One.

The Boeing 747, that currently serves as the means of air transport for President Trump, has been written about on The Conversation.

Here is that fascinating article:

ooOOoo

Air Force One is more than transportation – it has defined how presidents run the country and meet the world

Air Force One used to be a high-flying symbol of American technology, ingenuity and power. For many, it was also a source of national pride.

The current Boeing 747s that serve as Air Force One are a combination transport vehicle, command center, press room, medical center and apartment, complete with bedroom and office for the nation’s chief executive.

Now, to many, Air Force One has become scandalous.

On July 8, 2026, The New York Times reported that the latest version of the presidential aircraft – presented by Qatar as a gift to President Donald Trump – lacks the sophisticated countermeasures that were a ready defense for the 747s that had been in service since 1990. Critics immediately revived earlier claims that the new 747 was a corrupt transaction from the start. Trump later said the plane would be sent to be “maxed out” with upgrades.

This article is not part of that story. Nor is it the standard story of Air Force One that appears in numerous documentaries, which tend to be gee-whiz accounts of the amazing capacities of the president’s airplane.

I am a historian writing a book about the technologies that have shaped the long history of the American presidency, in which Air Force One looms large. I believe it is important to see Air Force One as more than a cool gadget or political flash point. Von Hardesty, a curator at the Smithsonian’s National Air and Space Museum, certainly understood this when he wrote that “by the end of the 20th century, Air Force One had evolved into an essential arm of the American Presidency.”

Put simply, the presidency as we know it today would have been impossible without Air Force One, which has shaped and defined that role for decades.

Horse-drawn carriage to the ‘Sacred Cow’

It was only recently that Americans or their presidents could imagine things this way. When presidents left the capital throughout most of the nation’s history, it was a lengthy, at times arduous, process that severed their connection with government offices.

As a result, presidents rarely traveled while in office and were more likely to depart Washington for extended vacations than for official business. Likewise, no serving president left the United States until Teddy Roosevelt visited the construction of the Panama Canal in 1906. Woodrow Wilson became the first sitting president to cross the Atlantic when he boarded the USS George Washington in 1918 to join the negotiations in Versailles at the end of World War I.

If few presidents got away from Washington to see the country and its residents before 1900, the flip side was also true: Few Americans saw presidential candidates or incumbents in person, especially Americans who lived outside the eastern third of the United States. Instead, the connection between presidents and average citizens was mediated through political parties, the press and eventually through broadcast media.

The first designated presidential aircraft arrived in 1933, but Franklin Roosevelt never flew on it. His first flight as president came in 1943, when American Airlines loaned a flying boat called the Dixie Clipper to ferry Roosevelt to meet with other Allied leaders at the Casablanca Conference. In 1945, Roosevelt traveled to Yalta on a Douglas VC-54C called the Sacred Cow, the first plane specifically built for presidential travel.

Despite these flights to important international meetings, Roosevelt and successors Harry Truman and Dwight Eisenhower made limited domestic use of aircraft, preferring instead to travel by railroad. International trips remained lengthy journeys in loud, propeller-driven aircraft that encountered the greater turbulence of lower altitudes.

All this changed in 1962, when President John Kennedy acquired a brand-new Boeing 707, the first jet-powered Air Force One.

Presidential ubiquity

Flying higher, faster and quieter than their predecessors, the jet aircraft used for Air Force One made possible one of the central facets of the modern presidency: The nation’s chief executive could be a ubiquitous player in national politics and world affairs.

Presidential travel increased dramatically, both in its frequency and in the number of stops on each trip. This was not simply the result of the growing use of air travel worldwide. Where Roosevelt, Truman and Eisenhower understood world leadership as their ability to coordinate American power from Washington, Kennedy and his successors sought to make themselves the center of the story.

This seemed particularly important during the Cold War. As the United States asserted its leadership in the struggle against the Soviet Union, American presidents positioned themselves as the symbols of freedom in opposition to communism.

Consider President Richard Nixon traveling to China in 1972 to normalize relations, or Ronald Reagan flying to Iceland for the 1986 Reykjavík conference with Soviet leader Mikhail Gorbachev to negotiate the future of intermediate-range nuclear missiles. The presence of a president at these conferences elevated both the importance of the event and the image of the president as a statesman who was able to quickly pivot back and forth from national to international leadership.
As American presidents struggled to maintain their power and their relevance after the end of the Cold War, their international travel only increased. Bill Clinton, George W. Bush and Barack Obama each made over twice the number of international trips as Ronald Reagan did.

These trips ranged from goodwill visits to maintain old alliances to attempts to build new connections after the collapse of the Soviet empire.

Presidents specifically visited international hot spots, positioning themselves as global peacemakers. The sight of the American president descending the long stairs from Air Force One, smiling and waving along the way, became a symbol of American diplomacy.

Official business – and campaigning

If Air Force One enabled presidents to announce themselves as statesmen abroad, it also revolutionized politics at home.

During the 1970s, the two major parties moved from selecting their nominees at national conventions to a system where state primaries decided who would lead the ticket.

This change emerged from demands that political power move from party leaders to party members. But a primary system would have been unimaginable without aircraft to shuttle candidates around the country. That was particularly important for incumbents, as air travel enabled them to be both sitting presidents and active candidates.

Presidents and their handlers learned how to combine official government business, which permitted the use of Air Force One, with campaign opportunities. These moments not only changed how presidents operated; they changed how Americans understood their presidents.

This change began with Kennedy’s use of the jet-powered Air Force One for domestic travel, including the tragic decision to visit Texas in November 1963, where he was assassinated. In just his first year in office, Bill Clinton visited 37 states over the course of 73 days.

Air Force One is a symbol of presidential power, but its problems only reinforce the fact that technology shapes the presidency.

The clearest demonstration was on 9/11. President Bush was in Florida that morning. Air Force One whisked him into the air, delivering him first to the safety of an Air Force base in Louisiana and then to the fortified headquarters of the U.S. Strategic Command in Nebraska, and still had him back at the White House by the end of the day.

It was a grim reminder of the other task for Air Force One: a safe transport for the president during a national crisis or nuclear armageddon. While the aircraft fulfilled its promise to keep the president safe in a crisis, its legendary communication systems faltered. Crucially, Bush struggled to coordinate with senior officials in Washington, leaving him momentarily out of the loop at a terrifying historical juncture.

The role that presidents have assumed at home and abroad, as well as the ways Americans interact with their presidents, have taken form through the possibilities – and the limitations – of presidential aircraft. Air Force One is not just a great way to travel or a nifty gadget, nor is it peripheral to the presidency. It is central to it.

Nonsense on Stilts

The book by Massimo Pigliucci.

The subtitle of the book is “How to Tell Science from Bunk“

I am up to page 48 and I read something that is so obvious but had not occured to me before now. I have spoken to friends and they, too, had not realised this.

Namely, that the fact that “…. a variation on the old latitudinal hypothesis ….. explains a major causal factor explaining the rise of more successful civilizations in Euroasia, say, than in sub-Saharan Africa or on the American continent, is that Euroasia expands along an East-West axis.“

This East-West expansion provides greater opportunity for the invention of agriculture and the domestication of, say, the horse. Simply because feed crops are easier to grow owing to the smaller change in weather patterns. Unlike, the North-South expansion, where there is the problem of having to adjust to different weather towards the North or towards the South.

Here is the book from Amazon.

The wildfire smoke

A useful article from The Conversation.

When I first read this article, I thought everyone will be aware, such is the awareness of wildfire smoke in so many places, and media.

Then I realised that this was wrong, and if only one or two people benefit from the advice then it should be republished. The original was on The Conversation.

Yes, breathing wildfire smoke can harm your health – here’s what you can do to protect yourself

Colleen E. Reid, University of Colorado Boulder

Wildfire smoke from fires burning in Canada and northern Minnesota has been pouring across the Great Lakes and northeastern U.S. states, turning skies an eerie shade of orange. In the West, smoke has also been spreading into communities in Colorado and neighboring states as more wildfires burn in hot, dry conditions in July 2026.

University of Colorado environmental health researcher Colleen Reid explains what’s in that smoke and why breathing it is a health concern everyone should be aware of.

What is in wildfire smoke?

Wildfire smoke is a complex mixture that includes nitrogen oxides, volatile organic compounds, polycyclic aromatic hydrocarbons, carbon monoxide, carbon dioxide and particulate matter. When homes or buildings also burn, they can release an even more toxic stew of chemicals from burning electronics, furniture, plastics, paints and much more.

What you see when you see a smoke plume or when the air is hazy with wildfire smoke are the tiny particles that are too small to fall to the ground right away with gravity.

These particles, which scientists call particulate matter, are very small – we measure them in microns. When you breathe them in, they can harm your health. The smaller the particles, the deeper they can get into your lungs and body.

Map shows heavy smoke and low air quality across the Great Lakes Region and into the Northeast
EPA air quality monitors show high risks from smoke in many parts of the Great Lakes and northeastern U.S. on July 15, 2026. Reds are considered very unhealthy levels. Purples are either extremely unhealthy for light purple or hazardous for areas in maroon. AirNow Fire and Smoke Map

You may have heard the term PM2.5. It means particles that are 2.5 microns or smaller in diameter, many times smaller than the width of a human hair. High concentrations of these particles in the air during wildfire smoke episodes are what trigger air quality alerts.

Has wildfire smoke been increasing recently, and why?

Yes, wildfires have become more frequent and more intense just in the past couple of decades, and when wildfires become more frequent and intense, so does the smoke.

Scientists have found that wildfires are becoming more frequent due to a variety of factors that include increases in fire weather – hot, dry, windy conditions that fuel the spread of fires due to climate change – as well as other natural and human factors. The reasons for the increases in wildfires vary in different parts of the world.

Other studies have found that wildfire smoke makes up an increasing portion of the PM2.5 in the air in the U.S., and in many areas it is offsetting the decreases in air pollution that the U.S. has gained through regulations of industrial and vehicle emissions under the Clean Air Act.

How could wildfire smoke affect my health?

Some effects of breathing wildfire smoke include shortness of breath, coughing, itchy or watery eyes, headaches, rashes and itchiness. But smoke can cause more serious harm. Numerous epidemiological studies have shown that hospitalizations and emergency department visits for asthma and other respiratory diseases increase during wildfire smoke events.

After you breathe in the particles, they cause inflammation and oxidative stress, and they can move into the blood and spread throughout the body, affecting other organ systems.

Breathing wildfire smoke has been associated with higher risk of preterm births and other issues during pregnancy, and potentially cardiovascular problems such as heart attacks and strokes, although the evidence for these effects are more mixed.

The longer-term health effects of wildfire smoke are less clear, but it is a growing area of research.

Where can I learn more about wildfire smoke risks where I live?

The first thing to do to protect yourself from wildfire smoke is to know how bad the smoke is and how long it is going to last.

One great place to get information for where you live on current wildfire smoke is fire.airnow.gov. You can zoom in on the map to where you live and find color-coded circles reflecting data from both U.S. EPA air-quality monitors and PurpleAir sensors that people have put in their homes.

The colors show the level of PM2.5 at that location and suggest the associated health risk.

To find out how wildfire smoke is expected to change over time in North America, you can look at maps from FireSmoke Canada and the U.S. Interagency Wildland Fire Air Quality Response Program.

What can I do to protect myself and my family from wildfire smoke?

First of all, depending on the level of the air quality index where you are, there are different recommendations. When wildfire smoke reaches unhealthy levels, stay indoors as much as possible, with doors and windows shut to keep the wildfire smoke out.

If you have an air cleaner, use it, but check the filter, as filters can fill up quickly. Similarly, check the filter on your home HVAC system and replace it if needed.

If you have to go outside, consider wearing a well-fitting N95, KN95 or KF94 mask. These masks can protect you from inhaling particles in the air around you. Looser masks, such as surgical masks, mostly protect others from what you breathe out instead. They do not have a tight seal around your mouth, and when you breathe in, the air with all of the particles can find its way around the sides of the mask.

Having a tight fit of the mask to your face is important so that when you breathe, the air is going through the mask and capturing the smoke particles rather than letting them into your body where they cause harm.

If your home is leaky and you can see haze inside, consider going to a public space, such as a library or mall, with a good HVAC system. Some municipalities have designated clean air spaces where anyone can go.

Thank you, Colleen, and thank you The Conversation. Lots of good advice.
