Welcome!

Beloved Pharaoh. Born: June 3rd., 2003 – Died: June 19th., 2017. A very special dog that will never be forgotten.

Dogs live in the present – they just are!  Dogs make the best of each moment uncluttered by the sorts of complex fears and feelings that we humans have. They don’t judge, they simply take the world around them at face value.  Yet they have been part of man’s world for an unimaginable time, at least 30,000 years.  That makes the domesticated dog the longest animal companion to man, by far!

As man’s companion, protector and helper, history suggests that dogs were critically important in man achieving success as a hunter-gatherer.  Dogs ‘teaching’ man to be so successful a hunter enabled evolution, some 20,000 years later, to farming,  thence the long journey to modern man.  But in the last, say 100 years, that farming spirit has become corrupted to the point where we see the planet’s plant and mineral resources as infinite.  Mankind is close to the edge of extinction, literally and spiritually.

Dogs know better, much better!  Time again for man to learn from dogs!

A sudden rainstorm, here at home

The power of water.

Last Saturday evening, the 5th September, 2026, we had a violent and sudden rainstorm. In twenty-four minutes 0.85” of rain fell. Luckily there was no damage.

On Thursday, The Conversation published a post about the potential dangers of hiking in canyons when storms hit,

Hiking canyons can quickly turn deadly when storms hit – what you should know before going in

Hiking a picturesque valley or climbing a craggy gorge are some of the most exhilarating experiences in nature. As a geologist, I have hiked and climbed some of the most intense terrains in the world, including in the Andes, Middle Eastern deserts, the Balkans and the Appalachians.

I am particularly drawn to canyons that provide beautiful windows into the rock record and the geologic history of a place. However, these narrow valleys can quickly become extremely dangerous when water pours in.

At Grand Canyon National Park in Arizona, at least two hikers died and a third was missing after powerful monsoon storms sent a deluge into one of the narrowest parts of the canyon on Aug. 29, 2026. Two of the survivors who were rescued described seeing the water quickly rise over the trail as they clung to a ledge, fearing they might never see their families again.

So, how do you balance a love for outdoor activity with managing this risk and hike canyons safely?

Why canyons are prone to flash floods

To understand the dynamics of a flash flood, it helps to start with the geomorphologic aspect – understanding the landforms and how they change over time.

In canyons and arroyos – steep gullies common to the Southwest – flash flooding can occur even when the heavy rainfall happens great distances away. A person can be hiking under clear skies in the canyon and not be aware that heavy rain falling upstream or even outside of the canyon means a disaster is unfolding.

The steep gradients and narrow passageways that define these landscapes channel the water, sending vast amounts of it rushing downstream. Under these conditions, water can rise quickly in the narrow space of a canyon.

The Grand Canyon flood involved heavy downpours in the heart of monsoon season. The intensity of the rainfall matters in a canyon. Even in arid regions, which generally get low amounts of rain annually, heavy rainfall within a short period of time can create devastating floods.

In 2018, a flash flood in Israel’s Tzafit Canyon – an environment similar to the part of the Grand Canyon where the 2026 flood occurred – claimed the lives of 10 recent high school graduates who were hiking in the canyon.

I grew up in that region and had hiked there many times, and I remember thinking about the incomprehensible suddenness: One moment you are appreciating the breathtaking views of the desert, and within minutes you are fighting a torrent of water you never imagined in such an arid place. A year’s worth of rain fell near the canyon that day.

The hydrogeologic aspect

How well the ground absorbs water also affects flood dynamics. Soils that are highly porous and permeable can transmit water easily vertically into the ground.

However, in arid regions such as Arizona and the Negev Desert, where Tzafit Canyon lies, the dry ground tends to form hardened crusts that make it harder for the water to sink in. That exacerbates surface flooding.

What’s more, the lack of vegetation in dry and rocky environments means that water can flow more rapidly down slopes.

What should hikers do to stay safe?

As an avid hiker, I value the beauty of nature and geology that canyons offer, and I believe in enjoying them. However, it is important to understand the risks and to prepare before hiking, climbing or backpacking in these areas.

Carefully study your environment before going in, so you know the risks and the escape routes that will let you get to safety in the event of a flash flood.

Gear up properly. Prepare for your trip so you have the equipment you need. Make sure you have a flashlight with extra batteries, a whistle to signal first responders, and extra clothes in case you get wet. If you know you will be hiking in high-risk water zones, you may consider an inflatable personal flotation device.

Talk to park rangers before going in so you know the current conditions and so someone knows where you’re going.

Always be aware of the weather – not just above you but upstream. Clear skies can be deceptive. An added challenge is that cellular service is often shaky in deep canyons and remote areas. Check the weather forecast before you go down a canyon, not just for the specific location, but also for the surrounding area. The National Weather Service provides warnings of flash floods and other extreme weather events.

When you are in a canyon, a good general guideline is to try to stay as high as possible and to be alert to the sound of an incoming flood. One person described the rush of water in the Grand Canyon sounding like a freight train.

If heavy rain starts, use extra caution and seek higher ground. Be aware that the timing of floods can vary widely – scientists analyzed 74,814 flash flood events in the U.S. and found the average duration was around 3½ hours, but some persisted for more than 48 hours. A flood can start quickly and strand people for long periods of time. Muddy water or debris in a normally clear stream are two signs of flooding developing. Rising water or the distant sound of rushing water is another clear warning to get to safety fast.

There are always risks in nature, but that does not mean you should avoid being out in nature. Planning ahead and hiking with caution and awareness can help you enjoy the beautiful outdoors and come back home safely.

There are a number of excellent tips in this article. The one that stood out for me was making sure that the park rangers know where you are going.

Being Happy

It is such a straightforward intention, but ….

……. it is so often hijacked by ‘life’.

A search found many articles but I shall just publish two.

The first is from a Google search. (An AI answer.)

ooOOoo

Finding happiness within yourself means shifting your focus from external things to your own inner peace and state of mind.

Practice Mindfulness and Gratitude

  • Be present: Notice the current moment instead of rushing through your day.
  • Count your blessings: Write down three things you are thankful for each day.
  • Savor good moments: Pause and absorb positive feelings when good things happen, even small ones.

Let Go of Mental Barriers

  • Stop seeking approval: Realize that your worth does not depend on what others think.
  • Observe your thoughts: Watch your negative thoughts pass by without judging or believing them.
  • Release the past: Forgive yourself and others for past mistakes instead of holding onto anger.

Care for Your Mind and Body

  • Get enough rest: Prioritize good sleep so your body can recharge.
  • Stay active: Move your body regularly to release natural mood-boosting chemicals.
  • Spend time in nature: Walk outside to calm your mind and feel grounded.

Connect With Yourself

  • Explore hobbies: Do things purely because you enjoy them, like reading, drawing, or listening to music.
  • Spend time alone: Learn what you like and get comfortable in your own company.
  • Help others: Perform small, random acts of kindness to bring joy to both yourself and those around you.

My current writing project is a book that will be called Better Than Before, about the most fascinating subject ever, the subject of habits. How do we make and break habits—really?

It was my interest in happiness that led me to the subject of habits, and of course, the study of habits is really the study of happiness. Habits are the invisible architecture of everyday life, and a significant element of happiness. If we have habits that work for us, we’re much more likely to be happy, healthy, productive, and creative. Or not.

When I talk to people about their happiness challenges, they often point to hurdles related to a habit they want to make or break.

Last week, I posted about the “Big Five,” the areas into which most people’s desired habits fall.

I asked for reader advice about two questions: had I overlooked any areas, and was there a better name than “Big Five”?

Thank you, readers! I got very helpful answers to both questions.

First: yes, indeed, I’d missed some important areas. Now I have seven areas.

Second: given the new number, a reader had a great idea for a snappy name: the Essential Seven.

Voila! The Essential Seven include…

1. Eat and drink more healthfully (give up sugar, eat more vegetables, drink less alcohol)

2. Exercise regularly

3. Save and spend wisely (save regularly, pay down debt, donate to worthy causes, make purchases that contribute to happiness or habits, pay taxes, stay current with expense reports)

4. Rest, relax, and enjoy (pursue a hobby instead of cruising the internet, enjoy the moment, stop checking email, get enough sleep, spend less time in the car, take time for myself)

5. Stop procrastinating, make consistent progress (practice an instrument, set aside two hours daily for uninterrupted work, learn a language, maintain a blog, keep a gratitude journal)

6. Simplify, clear, and organize (make the bed every day, file regularly, put keys away in the same place, recycle, give away unused clothing)

7. Engage more deeply—with other people, with God, with yourself, with the world (call family members, read the Bible every day, volunteer, spend time with friends, observe the Sabbath, spend time alone in nature)

Of course, the same habit might satisfy different needs for different people. For one person, yoga might be a form of exercise (#2), for someone else, a way to find mental rest (#4); for someone else, a spiritual practice (#7). And people value different habits. For one person, organized files might be a crucial tool for creativity; another person finds inspiration in random juxtapositions.

The argument I’ll make in Better Than Before is that when we change our habits, we change our lives. We can use decision-making to choose the habits we want to form, use willpower to get the habit started, then—and this is the best part—we can allow the extraordinary power of habit to take over. At that point, we’re free from the need to decide and the need to use willpower. We take our hands off the wheel of decision, and our foot off the gas of willpower, and rely on the cruise-control of habits. Mindfully, then mindlessly.

Before and after! It’s what we all crave.

So readers, what do you think of the Essential Seven—the name and the concepts themselves? I very much appreciate all the thoughtful comments that people posted. Very, very helpful.

I must say, it pleases me to have seven. I hate to quote Voldemort, but he was right when he observed, in Harry Potter and the Half-Blood Prince, “Isn’t seven the most powerfully magic number?”

ooOOoo

So there we are.

Always room for improvement, no matter the age or the circumstances.

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.

ooOOoo

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.

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.

How Dog Owners Can Spot Stress and Find Simple Ways to Feel Better

Busy dog parents balancing work, home, and a living creature’s needs often feel stressed without knowing what’s actually causing it. The core tension is that dog owner stressors can stack up quietly, pet care challenges, the emotional impact of dog ownership, and the daily responsibilities of dog owners, until even small issues feel heavy. Many people try to fix the feeling first, but the real relief starts with spotting the common stress triggers that keep showing up. Naming what’s draining the most makes it easier to feel steadier and more in control.

Calm Your Nervous System: 6 Everyday Stress Fixes

Once you’ve spotted your biggest dog-owner stress triggers (time crunch, money worry, behavior challenges, guilt, etc.), the goal is simple: lower the daily “background stress” with small moves you can actually repeat.

  1. Turn walks into stress-reduction exercise (without adding time): Keep your usual route, but add two “reset moments.” For 60 seconds, walk a little slower and drop your shoulders; then for 60 seconds, brisk-walk like you’re late. That quick contrast helps your body burn off stress chemistry and reminds your brain you’re safe and in control, especially helpful if your trigger is feeling rushed.
  2. Build one work-life boundary around dog care: Pick a single non-negotiable block that protects both you and your dog, like “no work messages during the first 15 minutes after the evening walk” or “lunch break happens outside with the dog.” This works because boundaries reduce the constant decision-making that keeps stress simmering. If you identified “always on” work as a trigger, start with the smallest boundary you can defend most days.
  3. Upgrade one meal for a steadier mood: Stress and diet can create a loop, when you’re frazzled, it’s easy to skip real food, then your energy crashes and everything feels harder. Choose one “anchor” meal (often breakfast) and add protein + fiber, like eggs and whole-grain toast, or yogurt with nuts and berries. Keep a simple backup for chaotic pet-care mornings so you don’t default to caffeine-only.
  4. Use a 2-minute deep breathing technique after a trigger event: When something spikes your stress, barking at the door, a messy accident, a tense email, try slow breathing: inhale through your nose for 4 seconds, exhale for 6 seconds, repeat for 10 rounds. Evidence linking slow-paced breathing with calmer “rest-and-digest” activity helps explain why this can feel like a volume knob for your nervous system. Pair it with a cue you’ll remember, like washing your hands after cleaning up.
  5. Practice a positive mindset that’s realistic (not forced): Do a quick “reframe + next step” script: name what’s hard, then name one controllable action. Example: “My dog’s reactivity is stressful… I can text my trainer and do a 3-minute pattern game before the next walk.” This is especially powerful if your trigger is guilt, because it shifts you from self-blame to problem-solving.
  6. Protect sleep hygiene with a dog-friendly bedtime plan: Decide on a consistent “dog last call” routine 30–45 minutes before lights out: water refresh, quick potty break, dim lights, then a calm settle. If your dog wakes you, keep the response boring and brief (no bright lights, no scrolling), so both of your brains learn nighttime isn’t playtime. Better sleep won’t erase stress, but it raises your capacity to handle it.

Explore 4 Alternative Stress-Relief Avenues You May Hear About

Once you’ve covered the basics, sleep, movement, breathing, and better daily boundaries, you might get curious about other stress-support options people talk about. Four alternative avenues you may hear about are:

  1. Meditation or mindfulness practices
  2. Ancient traditions like acupuncture
  3. Adaptogenic herbs like Ashwagandha
  4. Hemp-derived products like THCA diamonds

Simple Stress-Reset Habits You Can Repeat

Small habits matter because stress signals can be subtle in both people and dogs, and consistency makes them easier to notice and respond to. When you repeat a few simple routines, you build confidence, reduce guesswork, and create calmer days for the whole household.

Two-Minute Leash Check-In

  • What it is: Pause before walks and note posture, panting, and your own jaw tension.
  • How often: Daily
  • Why it helps: You spot stress early and choose a gentler pace.

Mindful Petting Reset

  • What it is: Use the ability to live each moment while slowly petting your dog.
  • How often: Daily
  • Why it helps: It shifts attention away from spiraling thoughts.

Three Micro-Moves

One Calm-Enrichment Swap

  • What it is: Replace one high-energy game with sniffing, licking, or a puzzle.
  • How often: 3 times weekly
  • Why it helps: Calmer activities help both of you downshift.

Weekly Recovery Plan

  • What it is: Pick one low-key outing and one true rest block.
  • How often: Weekly
  • Why it helps: Planning recovery prevents stress from stacking up.

Common Stress Questions Dog Owners Ask

Q: What if I’m too tired to do anything “extra” for stress?
A: Keep it tiny and tied to something you already do, like pausing before you clip the leash. Aim for one calming breath and one quick body scan of your dog’s face and posture. When you do less but do it consistently, it still counts.

Q: How can I tell if my dog is stressed or just excited?
A: Excitement usually looks loose and bouncy, and it settles once the fun starts. Stress often shows up as stiffness, tucked posture, lip licking, yawning, or scanning the environment. If you’re unsure, choose the gentler option: slow down, add distance, and reward calm.

Q: Can my dog’s behavior really affect my mental health?
A: Yes, it can, and you are not alone. Research links dog behavioural, health-related issues with poorer owner well-being, so feeling stretched makes sense. A practical next step is to pick one trigger to reduce this week, like avoiding crowded routes.

Q: What should I do when I miss a day and feel like I failed?
A: Treat it like brushing your teeth: you just restart at the next opportunity. Choose one “reset cue,” such as filling the water bowl, and do a 20-second calm check when you do it. Progress is built on returns, not perfection.

Q: Why doesn’t cuddling my dog always calm me down?
A: Comfort helps, but it is not a magic switch, especially if you are already overloaded. Many people rely on their pets, yet your body may still need sleep, food, or a quick movement break. Try pairing petting with slower breathing, then reassess what you need next.

Build Calm, Healthy Habits That Help You and Your Dog

Life with a dog can be joyful and still stressful, especially when the days are busy and emotions run high. The most reliable path isn’t doing everything perfectly, it’s using a steady, small-steps mindset to notice stress early and respond with simple, repeatable choices. Over time, that kind of stress management brings real benefits: a steadier mood for the owner, a more settled dog, and wellbeing reinforcement through small wins that keep stacking. Small, consistent care builds the calm both of you can feel.

Penny has done brilliantly with the ablove article.

Here we have our small chihuahua-cross, Cloudy, and he is a very loveable dog. But he can be a rascal and Jean has more patience with Cloudy than I have.

But I recognise that Cloudy came from a nearby dog rescue centre and Cloudy is so delighted at being loved by Jean and me, and by Oliver.

Once again, well done Penny!
