A very beautiful film

Man’s First Friend

Last Sunday Jean and I watched a Top Documentary Film about the origins of dogs. It was filmed in 2018 and was precious.

Here are the words that accompanied the film:

He has been an integral part of our existence for over 20,000 years. Throughout history, his contributions have been diverse and invaluable. He’s aided us in procuring sustenance, safeguarded our domesticated animals, served as a shield against adversaries, provided navigation during harsh conditions, and rescued us from imminent danger.

Presently, he offers solace, alleviating solitude and assisting us in managing the challenges of advancing age. He has evolved into an unwavering comrade. The origins of dogs raise intriguing questions: How did these remarkable creatures emerge? How did they ascend to such prominence in our lives? How did we forge a collaborative relationship, leveraging their distinct abilities? Moreover, what remarkable feats do they accomplish for us in contemporary times?

Prepare to embark on a journey that unveils the extraordinary escapades of these exceptional beings, showcasing their heroic deeds. Transitioning from wild wolves to beloved companions, from predatory instincts to steadfast friendship, we will traverse the globe to narrate the captivating narrative of how dogs earned their title: man’s first friend.

Director: Frédéric Fougea

Luckily the film, that runs for 90 minutes, is available on YouTube.

Here it is:

If you haven’t seen the film then, please, put some time aside to watch it. You will not be disappointed.

The Winter solstice

We pass from 2023 into 2024.

So here we are, 2024, and the year when I become 80! However, I still have eleven months before that happens. Like an amazing number of people, I do not really think long about this New Year but there are plenty that do.

Here is an article that explains much more. It is from The Conversation.

What winter solstice rituals tell us about indigenous people

On the day of winter solstice, many Native American communities will hold religious ceremonies or community events.

The winter solstice is the day of the year when the Northern Hemisphere has the fewest hours of sunlight and the Southern Hemisphere has the most. For indigenous peoples, it has been a time to honor their ancient sun deity. They passed their knowledge down to successive generations through complex stories and ritual practices.

As a scholar of the environmental and Native American religion, I believe, there is much to learn from ancient religious practices.

Ancient architecture

For decades, scholars have studied the astronomical observations that ancient indigenous people made and sought to understand their meaning.

One such place was at Cahokia, near the Mississippi River in what is now Illinois across from St. Louis.

In Cahokia, indigenous people built numerous temple pyramids or mounds, similar to the structures built by the Aztecs in Mexico, over a thousand years ago. Among their constructions, what most stands out is an intriguing structure made up of wooden posts arranged in a circle, known today as “Woodhenge.”

To understand the purpose of Woodhenge, scientists watched the sun rise from this structure on winter solstice. What they found was telling: The sun aligned with both Woodhenge and the top of a temple mound – a temple built on top of a pyramid with a flat top – in the distance. They also found that the sun aligns with a different temple mound on summer solstice.

Archaeological evidence suggests that the people of Cahokia venerated the sun as a deity. Scholars believe that ancient indigenous societies observed the solar system carefully and wove that knowledge into their architecture.

Scientists have speculated that the Cahokia held rituals to honor the sun as a giver of life and for the new agricultural year.

Complex understandings

Zuni Pueblo is a contemporary example of indigenous people with an agricultural society in western New Mexico. They grow corn, beans, squash, sunflowers and more. Each year they hold annual harvest festivals and numerous religious ceremonies, including at the winter solstice.

At the time of the winter solstice they hold a multiday celebration, known as the Shalako festival. The days for the celebration are selected by the religious leaders. The Zuni are intensely private, and most events are not for public viewing.

But what is shared with the public is near the end of the ceremony, when six Zuni men dress up and embody the spirit of giant bird deities. These men carry the Zuni prayers for rain “to all the corners of the earth.” The Zuni deities are believed to provide “blessings” and “balance” for the coming seasons and agricultural year.

As religion scholar Tisa Wenger writes, “The Zuni believe their ceremonies are necessary not just for the well-being of the tribe but for “the entire world.”

Winter games

Not all indigenous peoples ritualized the winter solstice with a ceremony. But that doesn’t mean they didn’t find other ways to celebrate.

The Blackfeet tribe in Montana, where I am a member, historically kept a calendar of astronomical events. They marked the time of the winter solstice and the “return” of the sun or “Naatosi” on its annual journey. They also faced their tipis – or portable conical tents – east toward the rising sun.

They rarely held large religious gatherings in the winter. Instead the Blackfeet viewed the time of the winter solstice as a time for games and community dances. As a child, my grandmother enjoyed attending community dances at the time of the winter solstice. She remembered that each community held their own gatherings, with unique drumming, singing and dance styles.

Later, in my own research, I learned that the Blackfeet moved their dances and ceremonies during the early reservation years from times on their religious calendar to times acceptable to the U.S. government. The dances held at the time of the solstice were moved to Christmas Day or to New Year’s Eve.

Today, my family still spends the darkest days of winter playing card games and attending the local community dances, much like my grandmother did.

Although some winter solstice traditions have changed over time, they are still a reminder of indigenous peoples understanding of the intricate workings of the solar system. Or as the Zuni Pueblo’s rituals for all peoples of the earth demonstrate – of an ancient understanding of the interconnectedness of the world.

This IS a rescue story.

A woman who knew no bounds when it came to rescuing three large dogs.

This is such a beautiful account of Veronica Shea taking action, and personal risks, to provide, firstly trust, and then love for Princess George, Grace and Steve, as they were named. The story was published on The Dodo.

Woman Visits Mountain Every Day To Convince Huge Dogs To Let Her Rescue Them

“They couldn’t be touched. They couldn’t be leashed. They were just terrified.”

By Elizabeth Claire Alberts

Published on the 26th October, 2023

In 2020, Veronica Shea was out hiking with her dog in the Angeles National Forest in California, when she spotted something strange moving ahead of them.

“We whip around the curve, and I look over and there was this huge black thing,” Shea told The Dodo. “He went up the side of a cliff.”

Veronica Shea

Shea followed the furry animal and came face to face with three malnourished dogs alone in the wilderness. Realizing the dogs had been abandoned, she knew she had to help them. Every day for several weeks, Shea trudged up the mountain to feed the dogs and work on gaining their trust.

Veronica Shea

Slowly, the dogs got used to her and even began eating out of her hand. But Shea had no idea how to get them off the mountain. If she trapped one dog, would the others flee? She knew she couldn’t do it alone.

Veronica Shea

When she asked for help, a whole team of rescuers stepped forward. Together, they carried equipment up the mountain and put together a makeshift cage. The rescuers carefully lured the dogs inside and carried them down the mountain.

The three dogs —mastiffs named Princess George, Grace and Steve, who are believed to be siblings — were safe now. But they still had a long journey ahead.

Veronica Shea

The rescuers approached Cheri Wulff Lucas, a well known dog behaviorist and trainer in California, to see if she could help the nervous dogs learn to trust again.

“They weren’t adoptable the way they came,” Lucas told The Dodo. “They couldn’t be touched. They couldn’t be leashed. They were just terrified.”

Princess George, Grace and Steve responded well to Lucas’ training. Still, they continued to have a “very strong startle reflex,” said Lucas. This made it difficult to find them the perfect home.

“It was going to take a very special home for them to go into because they’re not the kind of dogs that are going to go to the dog park,” Lucas said. “Even walking them on city streets would be a lot for them. And if they do spook, they weigh 125 pounds, so [they would be] very hard to contain.”

But Lucas knew the dogs were safe on her own property.

“I’m out in the middle of nowhere,” Lucas said. “There’s no traffic around here. You can’t even see another home from here. So if they did get out, they would just come back here to me.”

Veronica Shea

While Lucas never planned on keeping the dogs herself, that’s exactly what she ended up doing. This turned out to be the best decision for everyone. Princess George, Grace, and Steve continued to live in a safe and supportive environment. And Lucas discovered that the dogs could help her with her work as a trainer.

“If I get dogs that needs socialization — to be more familiar and less reactive with other dogs — I use my pack to help rehabilitate them,” Lucas said. “And all three of them are highly social with dogs. They know how to smell properly, how to not overpower the dog that needs the socialization. They’re just flawless. And that’s not something I taught them — they came that way.”

Veronica Shea

The threesome were particularly helpful when Lucas started working with another dog named Andi, who was rescued from a hoarding case.

“She had lived in a pen for seven years without human touch or being leashed or anything and she was terrified,” Lucas said. “They just came in and really made her feel comfortable. It was really sweet to see. They brought her around in a way that I never could as a human.”

Lucas ended up adopting Andi as well, bringing her personal pack of dogs to 12.

Princess George, Grace and Steve have been living with Lucas now for over three years, and they’re completely different dogs now.

“They’re incredibly playful,” Lucas said. “If you came to my house and did not know their backstory, you would think they were like any other dog.”

Lucas describes George as a “couch potato” who loves hanging around the house and socializing with the other dogs. Steve is the one who likes to play endless games of “chase” out in the yard. Grace remains a bit timid, but she shares a very close relationship with Steve.

“They’re pets — they’re really pets now,” she said. “They’re not cases for me anymore.”

ooOOoo

Lucas sums it up perfectly in that last sentence; “They’re pets – they’re really pets now,

Lucas reminds me of Jean for when we first met, in December 2007, Jean had more than twenty dogs at home, all rescues, and led to me publishing my first book in 2009: Learning from Dogs.

An inspiring TED Talk

Hannah Ritchie raises a very important question.

I was born in London before the end of World War II and to a great extent my upbringing was in the times of yesterday. But the world has moved on in many, many ways. It is too easy to say that we live in very strange times.

Thus it was enlightening to come across this talk, under the TED Talks banner, quite recently. I have great pleasure in sharing it with you. Plus, Hannah’s website is here. (From which I have taken the following words!)

(P.S. The YouTube video is just over thirteen minutes long. It automatically runs into the next video so you will have to stop it yourself.)

ooOOoo

The word “sustainability” gets thrown around a lot these days. But what does it actually mean for humanity to be sustainable? Environmental data scientist Hannah Ritchie digs into the numbers behind human progress across centuries, unpacking why the conventional understanding of sustainability is misleading and showing how we can be the first generation of humans to actually achieve it.

Why you should listen

Hannah Ritchie is deputy editor and research lead at Our World in Data, an online publication making data and research on the world’s largest problems accessible and understandable for non-experts. She is a senior researcher at the University of Oxford, where she studies how environmental issues intersect with others like poverty, global health and education. She has also done extensive research into the question of how to feed everyone in the world a nutritious diet without wrecking the planet. Her work has appeared in The New York TimesThe Washington PostVoxWired, BBCAl JazeeraThe Economist and New Scientist.

In 2022, Ritchie was named Scotland’s Youth Climate Champion. She is also an honorary fellow at the University of Edinburgh and Edinburgh Centre for Carbon Innovation, and a fellow at the Energy for Growth Hub, focused on ending global energy poverty. Her forthcoming book, The First Generation, makes an evidence-based case for why we have a meaningful chance to solve global environmental problems for the first time in human history.

The expansion of the Universe

I am reproducing a recent article published by The Conversation.

It is a reflection of the latest research undertaken by NASA, it is beyond fascinating!

ooOOoo

The universe is expanding faster than theory predicts – physicists are searching for new ideas that might explain the mismatch

Ryan Keeley, University of California, Merced

Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth.

To astronomers, the wavelength of light a galaxy emits is longer the faster the galaxy is moving away from us. The farther away the galaxy is, the more its light has shifted toward the longer wavelengths on the red side of the spectrum – so the higher the “redshift.”

Because the speed of light is finite, fast, but not infinitely fast, seeing something far away means we’re looking at the thing how it looked in the past. With distant, high-redshift galaxies, we’re seeing the galaxy when the universe was in a younger state. So “high redshift” corresponds to the early times in the universe, and “low redshift” corresponds to the late times in the universe.

But as astronomers have studied these distances, they’ve learned that the universe is not just expanding – its rate of expansion is accelerating. And that expansion rate is even faster than the leading theory predicts it should be, leaving cosmologists like me puzzled and looking for new explanations.

Dark energy and a cosmological constant

Scientists call the source of this acceleration dark energy. We’re not quite sure what drives dark energy or how it works, but we think its behavior could be explained by a cosmological constant, which is a property of spacetime that contributes to the expansion of the universe.

Albert Einstein originally came up with this constant – he marked it with a lambda in his theory of general relativity. With a cosmological constant, as the universe expands, the energy density of the cosmological constant stays the same.

Imagine a box full of particles. If the volume of the box increases, the density of particles would decrease as they spread out to take up all the space in the box. Now imagine the same box, but as the volume increases, the density of the particles stays the same.

It doesn’t seem intuitive, right? That the energy density of the cosmological constant does not decrease as the universe expands is, of course, very weird, but this property helps explain the accelerating universe.

A standard model of cosmology

Right now, the leading theory, or standard model, of cosmology is called “Lambda CDM.” Lambda denotes the cosmological constant describing dark energy, and CDM stands for cold dark matter. This model describes both the acceleration of the universe in its late stages as well as the expansion rate in its early days.

Specifically, the Lambda CDM explains observations of the cosmic microwave background, which is the afterglow of microwave radiation from when the universe was in a “hot, dense state” about 300,000 years after the Big Bang. Observations using the Planck satellite, which measures the cosmic microwave background, led scientists to create the Lambda CDM model.

Fitting the Lambda CDM model to the cosmic microwave background allows physicists to predict the value of the Hubble constant, which isn’t actually a constant but a measurement describing the universe’s current expansion rate.

But the Lambda CDM model isn’t perfect. The expansion rate scientists have calculated by measuring distances to galaxies, and the expansion rate as described in Lambda CDM using observations of the cosmic microwave background, don’t line up. Astrophysicists call that disagreement the Hubble tension.

The Hubble tension

Over the past few years, I’ve been researching ways to explain this Hubble tension. The tension may be indicating that the Lambda CDM model is incomplete and physicists should modify their model, or it could indicate that it’s time for researchers to come up with new ideas about how the universe works. And new ideas are always the most exciting things for a physicist.

One way to explain the Hubble tension is to modify the Lambda CDM model by changing the expansion rate at low redshift, at late times in the universe. Modifying the model like this can help physicists predict what sort of physical phenomena might be causing the Hubble tension.

For instance, maybe dark energy is not a cosmological constant but instead the result of gravity working in new ways. If this is the case, dark energy would evolve as the universe expands – and the cosmic microwave background, which shows what the universe looked like only a few years after its creation, would have a different prediction for the Hubble constant.

But, my team’s latest research has found that physicists can’t explain the Hubble tension just by changing the expansion rate in the late universe – this whole class of solutions falls short.

Developing new models

To study what types of solutions could explain the Hubble tension, we developed statistical tools that enabled us to test the viability of the entire class of models that change the expansion rate in the late universe. These statistical tools are very flexible, and we used them to match or mimic different models that could potentially fit observations of the universe’s expansion rate and might offer a solution to the Hubble tension.

The models we tested include evolving dark energy models, where dark energy acts differently at different times in the universe. We also tested interacting dark energy-dark matter models, where dark energy interacts with dark matter, and modified gravity models, where gravity acts differently at different times in the universe.

But none of these could fully explain the Hubble tension. These results suggest that physicists should study the early universe to understand the source of the tension.

The history of Oxygen!

A fascinating subject.

We take it for granted! Of that I am sure. But the question of how oxygen first came to be built up in our atmosphere is fascinating. There was a recent article written by Elizabeth Swanner, who is Associate Professor of Geology, Iowa State University that was published in The Conversation. It makes for a very interesting read.

A layered lake is a little like Earth’s early oceans − and lets researchers explore how oxygen built up in our atmosphere billions of years ago

Little Deming Lake doesn’t get much notice from visitors to Itasca State Park in Minnesota. There’s better boating on nearby Lake Itasca, the headwaters of the Mississippi River. My colleagues and I need to maneuver hundreds of pounds of equipment down a hidden path made narrow by late-summer poison ivy to launch our rowboats.

But modest Deming Lake offers more than meets the eye for me, a geochemist interested in how oxygen built up in the atmosphere 2.4 billion years ago. The absence of oxygen in the deep layers of Deming Lake is something this small body of water has in common with early Earth’s oceans.

On each of our several expeditions here each year, we row our boats out into the deepest part of the lake – over 60 feet (18 meters), despite the lake’s surface area being only 13 acres. We drop an anchor and connect our boats in a flotilla, readying ourselves for the work ahead.

Deming Lake is meromictic, a term from Greek that means only partially mixing. In most lakes, at least once a year, the water at the top sinks while the water at the bottom rises because of wind and seasonal temperature changes that affect water’s density. But the deepest waters of Deming Lake never reach the surface. This prevents oxygen in its top layer of water from ever mixing into its deep layer.

Less than 1% of lakes are meromictic, and most that are have dense, salty bottom waters. Deming Lake’s deep waters are not very salty, but of the salts in its bottom waters, iron is one of the most abundant. This makes Deming Lake one of the rarest types of meromictic lakes.

The lake surface is calm, and the still air is glorious on this cool, cloudless August morning. We lower a 2-foot-long water pump zip-tied to a cable attached to four sensors. The sensors measure the temperature, amount of oxygen, pH and amount of chlorophyll in the water at each layer we encounter. We pump water from the most intriguing layers up to the boat and fill a myriad of bottles and tubes, each destined for a different chemical or biological analysis.

My colleagues and I have homed in on Deming Lake to explore questions about how microbial life adapted to and changed the environmental conditions on early Earth. Our planet was inhabited only by microbes for most of its history. The atmosphere and the oceans’ depths didn’t have much oxygen, but they did have a lot of iron, just like Deming Lake does. By investigating what Deming Lake’s microbes are doing, we can better understand how billions of years ago they helped to transform the Earth’s atmosphere and oceans into what they’re like now.

Layer by layer, into the lake

Two and a half billion years ago, ocean waters had enough iron to form today’s globally distributed rusty iron deposits called banded iron formations that supply iron for the modern global steel industry. Nowadays, oceans have only trace amounts of iron but abundant oxygen. In most waters, iron and oxygen are antithetical. Rapid chemical and biological reactions between iron and oxygen mean you can’t have much of one while the other is present.

The rise of oxygen in the early atmosphere and ocean was due to cyanobacteria. These single-celled organisms emerged at least 2.5 billion years ago. But it took roughly 2 billion years for the oxygen they produce via photosynthesis to build up to levels that allowed for the first animals to appear on Earth.

At Deming Lake, my colleagues and I pay special attention to the water layer where the chlorophyll readings jump. Chlorophyll is the pigment that makes plants green. It harnesses sunlight energy to turn water and carbon dioxide into oxygen and sugars. Nearly 20 feet (6 meters) below Deming’s surface, the chlorophyll is in cyanobacteria and photosynthetic algae, not plants.

But the curious thing about this layer is that we don’t detect oxygen, despite the abundance of these oxygen-producing organisms. This is the depth where iron concentrations start to climb to the high levels present at the lake’s bottom.

This high-chlorophyll, high-iron and low-oxygen layer is of special interest to us because it might help us understand where cyanobacteria lived in the ancient ocean, how well they were growing and how much oxygen they produced.

We suspect the reason cyanobacteria gather at this depth in Deming Lake is that there is more iron there than at the top of the lake. Just like humans need iron for red blood cells, cyanobacteria need lots of iron to help catalyze the reactions of photosynthesis.

A likely reason we can’t measure any oxygen in this layer is that in addition to cyanobacteria, there are a lot of other bacteria here. After a good long life of a few days, the cyanobacteria die, and the other bacteria feed on their remains. These bacteria rapidly use up any oxygen produced by still photosynthesizing cyanobacteria the way a fire does as it burns through wood.

We know there are lots of bacteria here based on how cloudy the water is, and we see them when we inspect a drop of this water under a microscope. But we need another way to measure photosynthesis besides measuring oxygen levels.

Long-running lakeside laboratory

The other important function of photosynthesis is converting carbon dioxide into sugars, which eventually are used to make more cells. We need a way to track whether new sugars are being made, and if they are, whether it’s by photosynthetic cyanobacteria. So we fill glass bottles with samples of water from this lake layer and seal them tight with rubber stoppers.

We drive the 3 miles back to the Itasca Biological Station and Laboratories where we will set up our experiments. The station opened in 1909 and is home base for us this week, providing comfy cabins, warm meals and this laboratory space.

In the lab, we inject our glass bottle with carbon dioxide that carries an isotopic tracer. If cyanobacteria grow, their cells will incorporate this isotopic marker.

We had a little help to formulate our questions and experiments. University of Minnesota students attending summer field courses collected decades worth of data in Itasca State Park. A diligent university librarian digitized thousands of those students’ final papers.

My students and I pored over the papers concerning Deming Lake, many of which tried to determine whether the cyanobacteria in the chlorophyll-rich layer are doing photosynthesis. While most indicated yes, those students were measuring only oxygen and got ambiguous results. Our use of the isotopic tracer is trickier to implement but will give clearer results.

That afternoon, we’re back on the lake. We toss an anchor; attached to its rope is a clear plastic bag holding the sealed bottles of lake water now amended with the isotopic tracer. They’ll spend the night in the chlorophyll-rich layer, and we’ll retrieve them after 24 hours. Any longer than that and the isotopic label might end up in the bacteria that eat the dying cyanobacteria instead of the cyanobacteria themselves. We tie off the rope to a floating buoy and head back to the station’s dining hall for our evening meal.

Iron, chlorophyll, oxygen

The next morning, as we wait for the bottles to finish their incubation, we collect water from the different layers of the lake and add some chemicals that kill the cells but preserve their bodies. We’ll look at these samples under the microscope to figure out how many cyanobacteria are in the water, and we’ll measure how much iron is inside the cyanobacteria.

That’s easier said than done, because we have to first separate all the “needles” (cyanobacteria) from the “hay” (other cells) and then clean any iron off the outside of the cyanobacteria. Back at Iowa State University, we’ll shoot the individual cells one by one into a flame that incinerates them, which liberates all the iron they contain so we can measure it.

Our scientific hunch, or hypothesis, is that the cyanobacteria that live in the chlorophyll- and iron-rich layer will contain more iron than cyanobacteria that live in the top lake layer. If they do, it will help us establish that greater access to iron is a motive for living in that deeper and dimmer layer.

These experiments won’t tell the whole story of why it took so long for Earth to build up oxygen, but they will help us to understand a piece of it – where oxygen might have been produced and why, and what happened to oxygen in that environment.

Deming Lake is quickly becoming its own attraction for those with a curiosity about what goes on beneath its tranquil surface – and what that might be able to tell us about how new forms of life took hold long ago on Earth.

Managing eco-anxiety.

Republishing a recent article published by The Conversation.

Before I go to this article I want to talk briefly about the book the Myth of Normal or as the subtitle explains TRAUMA, ILLNESS & HEALING IN A TOXIC CULTURE.

Let me pick this closing paragraph of Chapter 20, on page 296:

Disconnection in all its guises – alienation, loneliness, loss of meaning and dislocation – is becoming our culture’s most plentiful product. No wonder we are more addicted, chronically ill, and mentally disordered than ever before, enfeebled as we are by such malnourishment of mind, body, and soul.

It is a very powerful book albeit not the easiest read in the world but still highly recommended.

Plus there is a YouTube video of Dr. Maté being interviewed in July, 2023 by Tara Westover (also a long video!).

Now to the main purpose of today’s post.

Keeping your cool in a warming world: 8 steps to help manage eco-anxiety

Karen Magruder, University of Texas at Arlington

In a world facing environmental challenges unprecedented in human history, it’s no surprise that eco-anxiety – a pervasive worry about the current and future state of our planet – has become an increasingly prevalent mental health issue.

As people witness the devastating impacts of climate change, deforestation and loss of biodiversity, it’s only natural to feel overwhelmed and disheartened. I happen to live in Phoenix, Arizona, a “heat apocalypse” city with dwindling water supplies, so I have some skin in the game.

But amid doom-and-gloom predictions, there is hope. As a therapist and clinical social work professor, I have seen firsthand how paralyzing eco-anxiety can be, and I’m dedicated to finding solutions. Here are a few evidence-based tips to tackle your climate woes.

What is eco-anxiety?

Eco-anxiety is a broad term that encompasses dread about environmental issues like pollution and disposal of toxic waste, as well as climate-specific fears, such as increasing rates of extreme weather events and sea-level rise.

Common symptoms of eco-anxiety include worry about future generations, trouble sleeping or concentrating, feelings of frustration and a sense of helplessness. These feelings can range from mild and fleeting concerns to deep despair, panic attacks and obsessive-compulsive behaviors.

Sound like you or someone you know? There are a number of tools that can help people cope with these feelings, summed up with the acronym UPSTREAM.

Understanding and self-compassion

Be kind to yourself and know that you are not alone in these feelings.

Caring about the world you live in does not make you a “crazy” alarmist. In fact, growing numbers of people across the globe feel the same way, with two-thirds of Americans reporting being at least somewhat worried about climate change in recent polls.

It makes sense that people would feel nervous when basic needs like safety and shelter are threatened. Give yourself grace, because beating yourself up for these very valid feelings will only make you feel worse.

Participate in the solution

It can be hard to feel empowered when environmental harms are taking a toll on your mental health, but the escalating global crisis still demands urgent attention. Instead of burying your head in the sand, use that mental discomfort as a catalyst for action.

Individual efforts to reduce your carbon footprint matter. Joining larger movements has the potential for even move significant impacts, as well as the potential to buffer anxiety, research shows. Volunteer your own unique passions, talents and skills to advocate for systemic changes that will benefit the planet and humanity.

When you feel anxious, use that energy as fuel for the fight. Harnessing eco-anxiety in this way can reduce your sense of powerlessness.

Self-talk

The weight of the climate crisis is heavy enough as it is – don’t let your brain make you feel even worse.

When it comes to thinking about climate change, a realistic mindset puts us in a “just right” psychological Goldilocks zone. Don’t numb your psychic wounds, but also don’t over-catastrophize.

As a therapist, I often help clients identify and reframe unhelpful thinking patterns. For example, while it is true that there are many environmental problems to grapple with, there is also positive news, so don’t discount it. Recognize and celebrate victories big and small.

Trauma: Process it so you can heal

The climate crisis has been conceptualized as a collective trauma, and many individuals are struggling with eco-grief from climate impacts that have already happened. Processing past trauma from events like weather disasters is a crucial step in enhancing your ability to cope with new experiences.

Even people who have not yet experienced significant climate impacts directly may have signs of pre-traumatic stress, a clinical term for the distress experienced in anticipation of a high-stress situation. A licensed mental health professional can help you process these emotions.

Reduce isolation

It’s no secret that having a strong social support network is a key ingredient for happiness. Surrounding yourself with compassionate, like-minded friends is also key to sustained efforts in doing your part to make a difference.

Consider joining or starting a Climate Cafe or similar group to talk about climate concerns. Visit a 10-step climate grief meeting. Join a local environmental organization. Or simply call up a friend when you need a listening ear.

Get outdoors and enjoy nature.

Go for a quiet walk in the woods and observe nature all around you – it’s a Japanese practice for relaxation known as forest bathing. Spend time gardening. Exercise outdoors or otherwise spend time outdoors in a place that is relaxing and restorative for you.

Acts of self-care

Self-care is paramount when it comes to managing the emotional toll of eco-anxiety.

Engaging in self-care practices, such as getting adequate sleep, eating healthy and having fun, helps us maintain a sense of balance in the face of overwhelming environmental concerns.

Remember what they teach you on airplanes – you should always put on your own oxygen mask before helping other passengers. Likewise, when we come from a place of wellness, we are better equipped to handle the stresses of eco-anxiety and make a difference in this area.

Mindfulness

Because eco-grief is focused on the past and eco-anxiety is future-oriented, reconnecting to the present moment is a powerful way to combat both.

By cultivating mindfulness – a nonjudgmental awareness of the present moment – people can become more attuned to their thoughts, feelings and bodily sensations in response to eco-anxiety triggers. This heightened self-awareness helps people to acknowledge worries without becoming consumed by them.

Mindfulness practices, such as meditation and deep breathing, provide a calming and grounding effect, helping to reduce stress and alleviate feelings of helplessness. Moreover, mindfulness fosters a deeper connection to nature and an appreciation for the present moment, which can counteract the sense of despair associated with future environmental uncertainties.

In the face of eco-anxiety, these strategies can build resilience, reminding everyone that they have the power to shape a more sustainable and hopeful future.

There’s a powerful reminder that we have the power to stay in the present, or to put it another way by cultivating mindfulness. There are quite a few websites on Mindfulness including this description of what Mindfulness is on the Mayo Clinic website.

Mindfulness is a type of meditation in which you focus on being intensely aware of what you’re sensing and feeling in the moment, without interpretation or judgment. Practicing mindfulness involves breathing methods, guided imagery, and other practices to relax the body and mind and help reduce stress.

Now that is something I should really focus on as I am terrible at being in the moment and nowhere else.

The Book – “The Climate Casino”

Three hundred plus pages of vital information.

I bought this book from Thriftbooks and was so fired up that I sat down and started reading it almost immediately. For as the back cover explains:

Climate change is profoundly altering our world in ways that pose major risks to human societies and natural systems. We have entered the Climate Casino and are rolling the global-warming dice, warns William Nordhaus. But there is still time to turn around and walk back out of the casino, and in this book the author explains how.

William Nordhaus

William Nordhaus is a brilliant economist as Fred Andrews describes above. Indeed he is the Sterling Professor of Economics at Yale University and he has his website here.

Now I am going straight to two videos.

The first is William Nordhaus receiving the Nobel Prize in 2018.

And the second is that lecture given at the same venue in 2018.

Hopefully you got to watch them both!
