There’s more to water than one might think.

This post attracted me and I wanted to share it with you.

Here in Oregon we are lucky because the ground water is of a high quality and there is plenty of it. At home we drink our water straight from our well without any filtering or chlorination. Have been doing that ever since we moved in back in 2012.

But water is a much deeper subject than I tend to think of and this article is an in-depth review of the topic. It is an article from The Conversation.

Water in space – a ‘Goldilocks’ star reveals previously hidden step in how water gets to planets like Earth

Without water, life on Earth could not exist as it does today. Understanding the history of water in the universe is critical to understanding how planets like Earth come to be.

Astronomers typically refer to the journey water takes from its formation as individual molecules in space to its resting place on the surfaces of planets as “the water trail.” The trail starts in the interstellar medium with hydrogen and oxygen gas and ends with oceans and ice caps on planets, with icy moons orbiting gas giants and icy comets and asteroids that orbit stars. The beginnings and ends of this trail are easy to see, but the middle has remained a mystery.

I am an astronomer who studies the formation of stars and planets using observations from radio and infrared telescopes. In a new paper, my colleagues and I describe the first measurements ever made of this previously hidden middle part of the water trail and what these findings mean for the water found on planets like Earth.

How planets are formed

The formation of stars and planets is intertwined. The so-called “emptiness of space” – or the interstellar medium – in fact contains large amounts of gaseous hydrogen, smaller amounts of other gasses and grains of dust. Due to gravity, some pockets of the interstellar medium will become more dense as particles attract each other and form clouds. As the density of these clouds increases, atoms begin to collide more frequently and form larger molecules, including water that forms on dust grains and coats the dust in ice.

Stars begin to form when parts of the collapsing cloud reach a certain density and heat up enough to start fusing hydrogen atoms together. Since only a small fraction of the gas initially collapses into the newborn protostar, the rest of the gas and dust forms a flattened disk of material circling around the spinning, newborn star. Astronomers call this a proto-planetary disk.

As icy dust particles collide with each other inside a proto-planetary disk, they begin to clump together. The process continues and eventually forms the familiar objects of space like asteroids, comets, rocky planets like Earth and gas giants like Jupiter or Saturn.

Two theories for the source of water

There are two potential pathways that water in our solar system could have taken. The first, called chemical inheritance, is when the water molecules originally formed in the interstellar medium are delivered to proto-planetary disks and all the bodies they create without going through any changes.

The second theory is called chemical reset. In this process, the heat from the formation of the proto-planetary disk and newborn star breaks apart water molecules, which then reform once the proto-planetary disk cools.

To test these theories, astronomers like me look at the ratio between normal water and a special kind of water called semi-heavy water. Water is normally made of two hydrogen atoms and one oxygen atom. Semi-heavy water is made of one oxygen atom, one hydrogen atom and one atom of deuterium – a heavier isotope of hydrogen with an extra neutron in its nucleus.

The ratio of semi-heavy to normal water is a guiding light on the water trail – measuring the ratio can tell astronomers a lot about the source of water. Chemical models and experiments have shown that about 1,000 times more semi-heavy water will be produced in the cold interstellar medium than in the conditions of a protoplanetary disk.

This difference means that by measuring the ratio of semi-heavy to normal water in a place, astronomers can tell whether that water went through the chemical inheritance or chemical reset pathway.

Measuring water during the formation of a planet

Comets have a ratio of semi-heavy to normal water almost perfectly in line with chemical inheritance, meaning the water hasn’t undergone a major chemical change since it was first created in space. Earth’s ratio sits somewhere in between the inheritance and reset ratio, making it unclear where the water came from.

To truly determine where the water on planets comes from, astronomers needed to find a goldilocks proto-planetary disk – one that is just the right temperature and size to allow observations of water. Doing so has proved to be incredibly difficult. It is possible to detect semi-heavy and normal water when water is a gas; unfortunately for astronomers, the vast majority of proto-plantary disks are very cold and contain mostly ice, and it is nearly impossible to measure water ratios from ice at interstellar distances.

A breakthrough came in 2016, when my colleagues and I were studying proto-planetary disks around a rare type of young star called FU Orionis stars. Most young stars consume matter from the proto-planetary disks around them. FU Orionis stars are unique because they consume matter about 100 times faster than typical young stars and, as a result, emit hundreds of times more energy. Due to this higher energy output, the proto-planetary disks around FU Orionis stars are heated to much higher temperatures, turning ice into water vapor out to large distances from the star.

Using the Atacama Large Millimeter/submillimeter Array, a powerful radio telescope in northern Chile, we discovered a large, warm proto-planetary disk around the Sunlike young star V883 Ori, about 1,300 light years from Earth in the constellation Orion.

V883 Ori emits 200 times more energy than the Sun, and my colleagues and I recognized that it was an ideal candidate to observe the semi-heavy to normal water ratio.

Completing the water trail

In 2021, the Atacama Large Millimeter/submillimeter Array took measurements of V883 Ori for six hours. The data revealed a strong signature of semi-heavy and normal water coming from V883 Ori’s proto-planetary disk. We measured the ratio of semi-heavy to normal water and found that the ratio was very similar to ratios found in comets as well as the ratios found in younger protostar systems.

These results fill in the gap of the water trail forging a direct link between water in the interstellar medium, protostars, proto-planetary disks and planets like Earth through the process of inheritance, not chemical reset.

The new results show definitively that a substantial portion of the water on Earth most likely formed billions of years ago, before the Sun had even ignited. Confirming this missing piece of water’s path through the universe offers clues to origins of water on Earth. Scientists have previously suggested that most water on Earth came from comets impacting the planet. The fact that Earth has less semi-heavy water than comets and V883 Ori, but more than chemical reset theory would produce, means that water on Earth likely came from more than one source.The Conversation

Now this was a long article and I hope some of you stayed with John’s piece until the very end.

It really shows how the water trail is a much greater and longer journey than I assumed.

The clue to making us human

A really fascinating article from The Conversation on Imagination.

The website The Conversation had another very interesting link to something that sorts out the humans from all other life forms. It is imagination!

Imagination makes us human – this unique ability to envision what doesn’t exist has a long evolutionary history

You can easily picture yourself riding a bicycle across the sky even though that’s not something that can actually happen. You can envision yourself doing something you’ve never done before – like water skiing – and maybe even imagine a better way to do it than anyone else.

Imagination involves creating a mental image of something that is not present for your senses to detect, or even something that isn’t out there in reality somewhere. Imagination is one of the key abilities that make us human. But where did it come from?

I’m a neuroscientist who studies how children acquire imagination. I’m especially interested in the neurological mechanisms of imagination. Once we identify what brain structures and connections are necessary to mentally construct new objects and scenes, scientists like me can look back over the course of evolution to see when these brain areas emerged – and potentially gave birth to the first kinds of imagination.

From bacteria to mammals

After life emerged on Earth around 3.4 billion years ago, organisms gradually became more complex. Around 700 million years ago, neurons organized into simple neural nets that then evolved into the brain and spinal cord around 525 million years ago.

Eventually dinosaurs evolved around 240 million years ago, with mammals emerging a few million years later. While they shared the landscape, dinosaurs were very good at catching and eating small, furry mammals. Dinosaurs were cold-blooded, though, and, like modern cold-blooded reptiles, could only move and hunt effectively during the daytime when it was warm. To avoid predation by dinosaurs, mammals stumbled upon a solution: hide underground during the daytime.

Not much food, though, grows underground. To eat, mammals had to travel above the ground – but the safest time to forage was at night, when dinosaurs were less of a threat. Evolving to be warm-blooded meant mammals could move at night. That solution came with a trade-off, though: Mammals had to eat a lot more food than dinosaurs per unit of weight in order to maintain their high metabolism and to support their constant inner body temperature around 99 degrees Fahrenheit (37 degrees Celsius).

Our mammalian ancestors had to find 10 times more food during their short waking time, and they had to find it in the dark of night. How did they accomplish this task?

To optimize their foraging, mammals developed a new system to efficiently memorize places where they’d found food: linking the part of the brain that records sensory aspects of the landscape – how a place looks or smells – to the part of the brain that controls navigation. They encoded features of the landscape in the neocortex, the outermost layer of the brain. They encoded navigation in the entorhinal cortex. And the whole system was interconnected by the brain structure called the hippocampus. Humans still use this memory system for remembering objects and past events, such as your car and where you parked it.

Groups of neurons in the neocortex encode these memories of objects and past events. Remembering a thing or an episode reactivates the same neurons that initially encoded it. All mammals likely can recall and re-experience previously encoded objects and events by reactivating these groups of neurons. This neocortex-hippocampus-based memory system that evolved 200 million years ago became the first key step toward imagination.

The next building block is the capability to construct a “memory” that hasn’t really happened.

Involuntary made-up ‘memories’

The simplest form of imagining new objects and scenes happens in dreams. These vivid, bizarre involuntary fantasies are associated in people with the rapid eye movement (REM) stage of sleep.

Scientists hypothesize that species whose rest includes periods of REM sleep also experience dreams. Marsupial and placental mammals do have REM sleep, but the egg-laying mammal the echidna does not, suggesting that this stage of the sleep cycle evolved after these evolutionary lines diverged 140 million years ago. In fact, recording from specialized neurons in the brain called place cells demonstrated that animals can “dream” of going places they’ve never visited before.

In humans, solutions found during dreaming can help solve problems. There are numerous examples of scientific and engineering solutions spontaneously visualized during sleep.

The neuroscientist Otto Loewi dreamed of an experiment that proved nerve impulses are transmitted chemically. He immediately went to his lab to perform the experiment – later receiving the Nobel Prize for this discovery.

Elias Howe, the inventor of the first sewing machine, claimed that the main innovation, placing the thread hole near the tip of the needle, came to him in a dream.

Dmitri Mendeleev described seeing in a dream “a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper.” And that was the periodic table.

These discoveries were enabled by the same mechanism of involuntary imagination first acquired by mammals 140 million years ago.

Imagining on purpose

The difference between voluntary imagination and involuntary imagination is analogous to the difference between voluntary muscle control and muscle spasm. Voluntary muscle control allows people to deliberately combine muscle movements. Spasm occurs spontaneously and cannot be controlled.

Similarly, voluntary imagination allows people to deliberately combine thoughts. When asked to mentally combine two identical right triangles along their long edges, or hypotenuses, you envision a square. When asked to mentally cut a round pizza by two perpendicular lines, you visualize four identical slices.

This deliberate, responsive and reliable capacity to combine and recombine mental objects is called prefrontal synthesis. It relies on the ability of the prefrontal cortex located at the very front of the brain to control the rest of the neocortex.

When did our species acquire the ability of prefrontal synthesis? Every artifact dated before 70,000 years ago could have been made by a creator who lacked this ability. On the other hand, starting about that time there are various archeological artifacts unambiguously indicating its presence: composite figurative objects, such as lion-man; bone needles with an eye; bows and arrows; musical instruments; constructed dwellings; adorned burials suggesting the beliefs in afterlife, and many more.

Multiple types of archaeological artifacts unambiguously associated with prefrontal synthesis appear simultaneously around 65,000 years ago in multiple geographical locations. This abrupt change in imagination has been characterized by historian Yuval Harari as the “cognitive revolution.” Notably, it approximately coincides with the largest Homo sapiens‘ migration out of Africa.

Genetic analyses suggest that a few individuals acquired this prefrontal synthesis ability and then spread their genes far and wide by eliminating other contemporaneous males with the use of an imagination-enabeled strategy and newly developed weapons.

So it’s been a journey of many millions of years of evolution for our species to become equipped with imagination. Most nonhuman mammals have potential for imagining what doesn’t exist or hasn’t happened involuntarily during REM sleep; only humans can voluntarily conjure new objects and events in our minds using prefrontal synthesis.

There we are! As the author of the article says: “Most nonhuman mammals have potential for imagining what doesn’t exist or hasn’t happened involuntarily during REM sleep; only humans can voluntarily conjure new objects and events in our minds using prefrontal synthesis.

It has been a very long journey for us humans to be equipped with imagination. One wonders what the next ten or twenty years will bring? Any thoughts you want to leave as comments?

Plastics in the ocean

A fascinating insight into recovered plastic.

Like so many others we do our little bit regarding plastic but do not properly think about the issue. I have to admit that I am not even sure if all plastics are harmful or just some.

But I comprehend art!

That is why I am republishing, with permission, this article from The Conversation.

My art uses plastic recovered from beaches around the world to understand how our consumer society is transforming the ocean

I am obsessed with plastic objects. I harvest them from the ocean for the stories they hold and to mitigate their ability to harm. Each object has the potential to be a message from the sea – a poem, a cipher, a metaphor, a warning.

My work collecting and photographing ocean plastic and turning it into art began with an epiphany in 2005, on a far-flung beach at the southern tip of the Big Island of Hawaii. At the edge of a black lava beach pounded by surf, I encountered multitudes upon multitudes of plastic objects that the angry ocean was vomiting onto the rocky shore.

I could see that somehow, impossibly, humans had permeated the ocean with plastic waste. Its alien presence was so enormous that it had reached this most isolated point of land in the immense Pacific Ocean. I felt I was witness to an unspeakable crime against nature, and needed to document it and bring back evidence.

I began cleaning the beach, hauling away weathered and misshapen plastic debris – known and unknown objects, hidden parts of a world of things I had never seen before, and enormous whalelike colored entanglements of nets and ropes.

I returned to that site again and again, gathering material evidence to study its volume and how it had been deposited, trying to understand the immensity it represented. In 2006, I formed the Drifters Project, a collaborative global entity to highlight these vagrant, translocational plastics and recruit others to investigate and mitigate ocean plastics’ impact.

My new book, “Ocean Gleaning,” tracks 17 years of my art and research around the world through the Drifters Project. It reveals specimens of striking artifacts harvested from the sea – objects that once were utilitarian, but have been changed by their oceanic voyages and come back as messages from the ocean.

Living in a plastic age

I grew up in what some now deem the age of plastic. Though it’s not the only modern material invention, plastic has had the most unforeseen consequences.

My father was a biochemist at the chemical company Union Carbide when I was a child in New Jersey. He played golf with an actor who portrayed “The Man from Glad,” a Get Smart-styled agent who rescued flustered housewives in TV commercials from inferior brands of plastic wrap that snarled and tangled. My father brought home souvenir pins of Union Carbide’s hexagonal logo, based on the carbon molecule, and figurine pencil holders of “TERGIE,” the company’s blobby turquoise mascot.

On the 2013 Gyre Expedition, Pam Longobardi traveled with a team of scientists, artists and policymakers to investigate and remove tons of oceanic plastic washing out of great gyres, or currents, in the Pacific Ocean, and make art from it.

Today I see plastic as a zombie material that haunts the ocean. It is made from petroleum, the decayed and transformed life forms of the past. Drifting at sea, it “lives” again as it gathers a biological slime of algae and protozoans, which become attachment sites for larger organisms.

When seabirds, fish and sea turtles mistake this living encrustation for food and eat it, plastic and all, the chemical load lives on in their digestive tracts. Their body tissues absorb chemicals from the plastic, which remain undigested in their stomachs, often ultimately killing them.

The forensics of plastic

I see plastic objects as the cultural archaeology of our time – relics of global late-capitalist consumer society that mirror our desires, wishes, hubris and ingenuity. They become transformed as they leave the quotidian world and collide with nature. By regurgitating them ashore or jamming them into sea caves, the ocean is communicating with us through materials of our own making. Some seem eerily familiar; others are totally alien.

A person engaging in ocean gleaning acts as a detective and a beacon, hunting for the forensics of this crime against the natural world and shining the light of interrogation on it. By searching for ocean plastic in a state of open receptiveness, a gleaner like me can find symbols of pop culture, religion, war, humor, irony and sorrow.

In keeping with the drifting journeys of these material artifacts, I prefer using them in a transitive form as installations. All of these works can be dismantled and reconfigured, although plastic materials are nearly impossible to recycle. I display some objects as specimens on steel pins, and wire others together to form large-scale sculptures.

I am interested in ocean plastic in particular because of what it reveals about us as humans in a global culture, and about the ocean as a cultural space and a giant dynamic engine of life and change. Because ocean plastic visibly shows nature’s attempts to reabsorb and regurgitate it, it has profound stories to tell.

I believe humankind is at a crossroads with regards to the future. The ocean is asking us to pay attention. Paying attention is an act of giving, and in the case of plastic pollution, it is also an act of taking: Taking plastic out of your daily life. Taking plastic out of the environment. And taking, and spreading, the message that the ocean is laying out before our eyes.

Pam at one point describes the ocean plastic”… because of what it reveals about us as humans in a global culture, and about the ocean as a cultural space and a giant dynamic engine of life and change …”. It raises questions that I can only ponder the answer. Ultimately, are there too many inhabitants on this planet? What does the next generation think? Is there an answer?

Search and rescue team save dog near frozen waterfall in Utah 

The dog separated from its owner on Christmas Eve.

By Teddy Grant, December 27, 2022.

A dog that was stranded near a frozen waterfall in Utah on Christmas Eve was saved by search and rescue officials and reunited with her owner.

According to the Weber County Sheriff’s Office Search and Rescue, a local man was hiking near Waterfall Canyon on Saturday when he became separated from his dog Nala.

The unidentified hiker couldn’t find Nala by nightfall and resumed his search the morning of Christmas Day, the sheriff’s office wrote on its Facebook page.

The hiker’s family members contacted authorities around 1:00 p.m., local time, saying he wasn’t responding to their calls or text messages, officials said.

Nala’s owner answered one of the phone calls once he regained cellphone service and was able to let people know that Nala was around the waterfall, but couldn’t reach her because of the steepness and the icy condition of the terrain, according to Weber County Sheriff’s Office Search and Rescue.

A grab from video posted by Weber County Sheriff’s Office Search and Rescue shows the dog Nala at Waterfall Canyon in Ogden, Utah, Dec. 25, 2022.

The search and rescue team responded to the call and were able to save a skittish Nala after a little coaxing, officials said.

“Nala was cold with a few minor injuries, but was able to hike down with the rescuers,” officials wrote. “She is one tough puppy! Once reaching the trailhead parking lot, both human and canine couldn’t have been happier to be reunited.”

According to Waterfall Canyon it is a “moderately challenging,” 2.4-mile trail near Ogden, Utah, according to AllTrails. Ogden is around 38 miles north of Salt Lake City.

I’m sure you read that the human and the dog were very grateful to be reunited.

The end maybe in sight!

A rather gloomy analysis about the next few years!

One makes decisions all one’s life. But too few of us are making decisions that will prevent our planet from over-heating.

Patrice Ayme wrote a comment in a recent post that said (in part): “However we are tracking to a much higher temperature: + 7 (seven) Celsius in some now temperate parts… imminently. That is going to be catastrophic.”

There is a terrible change going on right now. From the deforestation in the Amazon rainforest to the unseasonable heat in Europe, as reported in the Guardian newspaper: “The result of this advection has been anomalously warm temperatures across large parts of Europe – in particular across France and Spain, where temperatures soared to over 10C above normal. Maximum temperatures widely exceeded 30C in parts of Spain on Thursday, with 35.2C measured at Morón de la Frontera, south-east of Seville.

One would think that our governments would be pulling together in order to have a co-ordinated global plan. But there’s no sight of that yet. What we do have is a sort of craziness of Governments that causes me to lament over our, as in a global ‘our’, distractions. We are running out of time!

The Oligarch’s Oligarch

Published 30th October 2022.

Just as we need to get the money out of politics, we have been gifted a Prime Minister who represents the ultra-rich.

By George Monbiot, published in the Guardian 26th October 2022

Before we decide what needs to change, let’s take stock of what we have lost. I want to begin with what happened last week. I don’t mean the resignation of the prime minister. This is more important.

Almost all the media reported a scripted comment by the newly reinstated home secretary, Suella Braverman, about the “Guardian-reading, tofu-eating wokerati”. Astonishingly, scarcely any of them reported what she was doing at the time. She was pushing through the House of Commons the most repressive legislation of the modern era.

Under the public order bill, anyone who has protested in the previous five years, or has encouraged other people to protest, can be forced to “submit to … being fitted with, or the installation of, any necessary apparatus” to monitor their movements. In other words, if you attend or support any protest in which “serious disruption to two or more individuals or to an organisation” occurs, you can be forced to wear an electronic tag. “Serious disruption” was redefined by the 2022 Police Act to include noise.

This is just one of a series of astounding measures in the bill, which has been hardly remarked upon in public life as it passes through Britain’s legislature. What we see here is two losses in one moment: the final erasure of the right to protest, and political journalism’s mutation from reporting substance to reporting spectacle. These are just the latest of our losses.

So extreme has inequality become, and so dangerous is the combination of frozen wages, lagging benefits, rising rents and mortgage repayments, soaring bills and food inflation, that millions of people are being pushed towards destitution. Unless something changes, many will soon lose their homes. In the midst of this crisis, we have been gifted a prime minister who owns four luxury “homes”. One of them is an empty flat in Kensington that he reserves for visiting relatives.

While Rishi Sunak was chancellor, the government repeatedly delayed its manifesto promise to ban no-fault evictions. Landlords are ruthlessly exploiting this power to throw their tenants on to the street or use the threat to force them to accept outrageous rent rises and dismal conditions. Had Sunak’s “help to buy” mortgage scheme succeeded (it was a dismal flop), it would have raised house prices, increasing rents and making ownership less accessible: the opposite of its stated aim. But this, as with all such schemes, was surely its true purpose: to inflate the assets of existing owners, the Conservative party’s base.

Public services are collapsing at breathtaking speed. Headteachers warn that 90% of schools in England could run out of money next year. NHS dentistry is on the verge of extinction. Untold numbers are now living in constant pain and, in some cases, extracting their own teeth. The suspicion that the NHS is being deliberately dismembered, its core services allowed to fail so that we cease to defend it against privatisation, rises ever higher in the mind.

But Sunak appears determined only to hack ever further. Sitting on a family fortune of £730m, he seems unmoved by the plight of people so far removed from him in wealth that they must seem to exist on another planet. He is the oligarch’s oligarch, ever responsive to the demands of big capitaland the three offshore plutocrats who own the country’s biggest newspapers, oblivious of the needs of the 67 million people who live here.

After 12 years of Conservative austerity and chaos, the very rich have taken almost everything. They have even captured virtue. They now appropriate the outward signs of an ethical life while continuing – despite or because of their organic cotton jackets and second homes, their electric cars and pasture-fed meat, their carbon offsets and ayahuasca retreats, philanthropy and holidays in quiet resorts whose palm-thatched cabins mimic the vernacular of the people evicted to make way for them – to grasp the lion’s share of everything.

Corruption is embedded in public life. Fraud is scarcely prosecuted. Organised crime has been so widely facilitated, through the destruction of the state’s capacity to regulate everything from money laundering to waste dumping, that you could almost believe it was deliberate. Our rivers have been reduced to sewers, our soil is washing off the land, the planning system is being dismantled, and hundreds of environmental laws are now under threat. We hurtle towards Earth systems oblivion, while frenetically talking about anything but.

In other words, it’s not just a general election we need, it’s a complete rethink of who we are and where we stand. It’s not just proportional representation we need, but radical devolution to the lowest possible levels at which decisions can be made, accompanied by deliberative, participatory democracy. It’s not just new lobbying laws we require, but a comprehensive programme to get the money out of politics, ending all private political donations, breaking up the billionaire press and demanding full financial transparency for everyone in public life. We should seek not only the repeal of repressive legislation, but – as civil disobedience is the bedrock of democracy – positive rights to protest.

All this now feels far away. Jeremy Corbyn offered some (though by no means all) of these reforms. Keir Starmer offers none. Though Labour MPs voted against the public order bill, his only public comment so far has been to endorse its headline policy: longer sentences for people who glue themselves to roads. But if the Labour party or its future coalition partners can persuade him to agree to just one aspect of this programme, proportional representation, we can start work on the rest, building the political alliances that could transform the life of this nation. Without PR, we’re stuck with a dysfunctional duopoly, in hock to the billionaire press and the millionaires it appoints to govern us. We cannot carry on like this.

So much is really telling but I just want to draw your attention to this sentence: In other words, it’s not just a general election we need, it’s a complete rethink of who we are and where we stand.

It is not just in England and Wales but also in the USA. Indeed, most of the countries in the world.

Here is an excerpt from the latest email from The Economist. It presages the COP27 to be held in Egypt next week.

By burning fossil fuels, humans have altered Earth’s atmosphere, which has consequences for almost everything on the planet. It is reshaping weather systems and coastlines, transforming where crops can be grown, which diseases thrive, and how armies fight . Rising temperatures affect geopolitics, migration, ecosystems and the economy. Over the next century and beyond, climate change—and the responses to it—will remake societies and the world.

And a paragraph later:

This week I wrote about the seven texts I recommend as an introduction to the climate crisis—and explained why each is worth turning to—as a part of our “Economist reads” series. They range from Bill Gates’s assessment of technological solutions to a discussion of international justice by the former UN High Commissioner on Human Rights. One book I find myself recommending over and over again is “What We Know About Climate Change” by Kerry Emanuel, an atmospheric scientist at MIT. At 88 pages, it is a blessedly short, readable primer on the science, history and economics of climate change. The climate crisis touches everything. Understanding it, even a little, is essential for anyone who is engaged with the world and its future. This is a good place to start

Please follow this advice because it is an excellent place to start.

I wish with all my heart that I am wrong and maybe, just maybe, I am having a ‘down in the dumps’ day. Whatever, my judgement is that we have a few more years at most to find out.

The wonders of soil!

Jane Zelikova gives a very powerful TED Talk.

The promotion for this TED Talk appeared in my ‘in box’ last week and I was curious as to its contents. So I watched the talk on Sunday afternoon and was amazed. This is so much more significant to all of us than the title suggests.

First watch the talk.

Then some background to Jane, who is a ecosystem scientist:

Dr. Tamara Jane Zelikova works at the intersection of climate science and policy. Her work focuses on advancing the science of carbon removal and she has published in scientific journals like Nature and Proceedings of the National Academy of Sciences, written and contributed to climate policy reports and published articles in popular media outlets like Scientific American. She is currently the executive director of the Soil Carbon Solutions Center at Colorado State University, where she works with leading scientists to build the tools and approaches needed to accelerate the deployment of credible soil-based climate solutions, measure their impacts and bring them to scale.

That then led me to the Soil Carbon Solutions Center website and this is a site you should visit. A little piece from their About section:

Unlocking the potential of soil for a more sustainable planet

Soil is one of the largest natural carbon reservoirs and an important climate mitigation tool that is ready to deploy today. Accelerating the adoption of regenerative agricultural practices that build soil carbon on working lands offers the potential to substantially draw down atmospheric carbon while improving the environmental, economic and social sustainability of food, fiber and bioenergy production.

Please, please watch the TED Talk!

Creating a healthy environment…

… for your dogs!

How To Create a Healthy, Eco-Friendly Environment for Your Dog

As a dog owner, it’s perfectly normal to want an environment for your canine companion that is fun, happy, and healthy. That includes making sure they have a clean and secure place that’s comfortable and safe, as well as free from hazardous materials and harmful pests. 

Creating a healthy environment for your dog is easier than you might think. By dedicating a specific space to your pooch and making some simple swaps, you can be an eco-friendly pet parent, doing something good for the planet and your pup all at once. 

Create a Safe Space

First and foremost, try to create a safe space in your home for your dog. You can always consider a pet room, but even just an area in your living room or a comfy crate can do the trick.

Having a designated area for your dog in your home can make a big difference. Dogs are den animals and like having their own safe space to go to. While you don’t necessarily need to dedicate a whole room to your four-legged friend, your space should be pet-proofed to keep them safe.

That includes keeping things organized and clearing up clutter, so your dog doesn’t get into or chew on things they shouldn’t. You can also use baby gates to keep your dog in their space or to prevent them from going into areas of your home that haven’t been pet-proofed.

Use Eco-friendly Cleaning Products

Once you have set up that space, it’s important to keep it clean for your dog. Between rest and play and dinner time, it’s all too easy for your home to get dirty quickly. This means you have to keep your home clean, regularly pick up after your dog, and sanitize their space.

However, you must keep them away from potentially toxic substances — including the supplies you use to clean their area. Make sure your dog can’t get to any of the following: 

  • Bleach
  • Aerosols
  • Ammonia
  • Phenol
  • Formaldehyde

You’ll quickly learn to become a “label reader” when it comes to the cleaning products you choose. Not only are the above ingredients bad for your pet, but they can also damage the environment. 

When shopping for cleaning supplies, choose all-natural products as often as possible. Alternatively, consider making your own so you know exactly which ingredients are used. Vinegar, baking soda, and lemon juice are all common household items that you can use in cleaners — and they’re better for your pet and the planet.

Keep Pests Away

Creating a safe environment for your pet also means protecting your pooch from pests. You might not be able to control what comes into your house — especially since many pests can sneak in through tiny cracks — but you can discourage them from bothering your dog. You can do so while still making your yard a fun place for your dog.

You can reduce the risk of certain bugs and rodents entering your home by keeping your yard clean and trimmed. Don’t give wild animals a space to “hang out” and enjoy. The more time they spend in your yard, the more likely it is that they’ll get inside.

Additionally, the more wildlife you have in your yard, the more likely it is that your dog will bring in fleas or ticks that have “jumped” from raccoons, possums, or mice. Pests like fleas and ticks can be especially harmful to dogs, and they’re quick to get into rugs, carpets, and furniture, which can end up putting everyone’s health at risk. You can vacuum frequently if you’ve seen your dog with a tick or fleas and utilize some of the cleaning supplies listed earlier to deter them from sticking around. 

If you see a bug on your dog, give them a thorough brushing and use natural shampooing solutions to get rid of the fleas quickly. Keep their fur trimmed back neatly and make sure they’re as clean as possible. Regular baths and grooming can also help keep pests away from your pet and ensure your dog doesn’t bring any extra visitors into your home.

Are you sensing a pattern? 

A clean, healthy home typically means a happier, safer space for dogs. Whether you’re trying to live more sustainably or just focus on more natural ways of doing things, these suggestions will get you on the right track. Not only will your dog have a secure and pet-friendly environment to enjoy, but you can feel good knowing you’re doing something to improve the health of your entire family, as well as the future of the planet.

A disturbing report from NASA.

About the 2022 Artic Summer Sea Ice.

There’s no way to make this pleasant; the Arctic Summer Sea Ice tied for the tenth lowest on record.

According to satellite observations, Arctic sea ice reached its annual minimum extent (lowest amount of ice for the year) on Sept. 18, 2022. The ice cover shrank to an area of 4.67 million square kilometers (1.80 million square miles) this year, roughly 1.55 million square kilometers (598,000 square miles) below the 1981-2010 average minimum of 6.22 million square kilometers (2.40 million square miles).

The average September minimum extent record shows significant declines since satellites began measuring consistently in 1978. The last 15 years (2007 to 2021) are the lowest 15 minimum extents in the 43-year satellite record.

As I said, a sorry tale for which there is no good news. I wish there were!

Ancient history of the climate.

Showing that droughts have been in evidence for 1,000 years or more!

It is very easy, well it is for me, to think that the changes we are seeing in the climate are purely recent. There is no question that we are experiencing changes in the global climate. But it would be too easy to think that these changes are only the result of recent times.

My way of an introduction to this post from The Conversation.

1,000-year-old stalagmites from a cave in India show the monsoon isn’t so reliable – their rings reveal a history of long, deadly droughts.

Published on the 19th September, 2022 by:

In a remote cave in northeast India, rainwater has slowly dripped from the ceiling in the same spots for over 1,000 years. With each drop, minerals in the water accumulate on the floor below, slowly growing into calcium carbonate towers known as stalagmites.

These stalagmites are more than geological wonders – like tree rings, their layers record the region’s rainfall history. They also carry a warning about the potential for catastrophic multiyear droughts in the future. 

By analyzing the geochemistry of these stalagmites in a new study published Sept. 19, 2022, in the Proceedings of the National Academy of Sciences, we were able to create the most precise chronology yet of the summer Indian monsoon over the past millennium. It documents how the Indian subcontinent frequently experienced long, severe droughts unlike any observed in the last 150 years of reliable monsoon rainfall measurements. 

The drought periods we detected are in striking synchrony with historical accounts of droughts, faminesmass mortality events and geopolitical changes in the region.

They show how the decline of the Mughal Empire and India’s textile industries in the 1780s and 1790s coincided with the most severe 30-year period of drought over the millennium. The depth and duration of the drought would have caused widespread crop failures and the level of famine discussed in written documentsat the time. 

Another long drought encompasses the 1630-1632 Deccan famine, one of the most devastating droughts in India’s history. Millions of people died as crops failed. Around the same time, the elaborate Mughal capital of Fatehpur Sikri was abandoned and the Guge Kingdom collapsed in western Tibet.

Our findings have important implications today for water planning in a warming world, particularly for India, which, with its vast monsoon-reliant agriculture industry, is on pace to soon be the most populous country on the planet.

Why the monsoon’s history matters

Scientists began systematically measuring India’s monsoon rainfall with instruments around the 1870s. Since then, India has experienced about 27 regionally widespread droughts. Among them, only one – 1985 to 1987 – was a three-year consecutive drought or worse.

The apparent stability of the Indian monsoon in that data might lead one to surmise that neither protracted droughts lasting multiple years nor frequent droughts are intrinsic aspects of its variability. This seemingly reassuring view currently informs the region’s present-day water resource infrastructure.

However, the stalagmite evidence of prolonged, severe droughts over the past 1,000 years paints a different picture.

It indicates that the short instrumental period does not capture the full range of Indian monsoon variability. It also raises questions about the region’s current water resources, sustainability and mitigation policies that discount the possibility of protracted droughts in the future.

How do stalagmites capture a region’s monsoon history?

To reconstruct past variations in rainfall, we analyzed stalagmites from Mawmluh cave, near the town of Cherrapunji in the state of Meghalaya – one of the wettest locations in the world.

Stalagmites are conelike structures that grow slowly from the ground up, typically at a rate of about one millimeter every 10 years. Trapped within their growth layers are minute amounts of uranium and other elements that were acquired as rainwater infiltrated the rocks and soil above the cave. Over time, uranium trapped in stalagmites decays into thorium at a predictable pace, so we can figure out the age of each stalagmite growth layer by measuring the ratio of uranium to thorium.

The oxygen in rainwater molecules comes in two primary types of isotopes – heavy and light. As stalagmites grow, they lock into their structure the oxygen isotope ratios of the percolating rainwater that seeps into the cave. Subtle variations in this ratio can arise from a range of climatic conditions at the time the rainwater originally fell.

Our previous research in this area showed that variations in oxygen isotope ratios in rainwater, and consequently, in stalagmites, track changes in the relative abundance of different moisture sources that contribute to summer monsoon rainfall.

During years when monsoon circulation is weak, rainfall here is primarily derived from the moisture that evaporated from the nearby Arabian Sea. During strong monsoon years, however, atmospheric circulation brings copious amounts of moisture to this area all the way from the southern Indian Ocean.

The two moisture sources have quite different oxygen isotope signatures, and this ratio is faithfully preserved in the stalagmites. We can use this clue to learn about the overall strength of the monsoon intensity at the time the stalagmite formed. We pieced together the monsoon rainfall history by extracting minute amounts of calcium carbonate from its growth rings and then measuring the oxygen isotope ratios. To anchor our climate record to precise calendar years, we measured the uranium and thorium ratio.

Stalagmites grow from the ground, and stalactites grow from above. These are in Mawmluh Cave, where the authors conducted their research. Gayatri Kathayat.

Next steps

The paleoclimate records can usually tell what, where and when something happened. But often, they alone cannot answer why or how something happened. 

Our new study shows that protracted droughts frequently occurred during the past millennia, but we do not have a good understanding of why the monsoon failed in those years. Similar studies using Himalayan ice cores, tree rings and other caves have also detected protracted droughts but face the same challenge. 

In the next phase of our study, we are teaming up with climate modelers to conduct coordinated proxy-modeling studies that we hope will offer more insight into the climate dynamics that triggered and sustained such extended periods of drought during the past millennium.

ooOOoo

So there we are. Droughts are a thing of the ancient past. But only a partial understanding for why the monsoons failed is known. Despite these modern times with so much general access to knowledge there are still things that we do not know!

Finally, one hopes that the next phase of their study will be along in reasonable time! I would love to report on it.
