The imminent climate change crisis

But a positive TED Talk on the situation.

There have been so many disastrous activities on climate change, and I am not belittling them, but it was amazing to come across a TED Talk last Saturday that I watched. But first the speaker, Asmeret Asefaw Berhe, who was born in Asmara, Eritrea. Her bio (in part):

From WikiPedia:

ooOOoo

Asmeret Asefaw Berhe is a soil biogeochemist and political ecologist who is the current Director of the Office of Science at the US Department of Energy. She was previously the Professor of Soil Biogeochemistry and the Ted and Jan Falasco Chair in Earth Sciences and Geology in the Department of Life and Environmental Sciences; University of California, Merced.[1] Her research group worked to understand how soil helps regulate the Earth’s climate.

Advocacy and global impact work

Berhe’s work at the intersection of soil, climate change, and political ecology lends itself well to a number of global issues. During her graduate career, she was a member of the working group that produced the Millennium Ecosystem Assessment, which was called for by the United Nations Secretary Kofi Annan to assess the impact of humans on the environment. She was one of the lead authors on the 2005 report’s chapter on “Drivers of Change in Ecosystem Condition and Services.”[19] The Assessment received the Zayed International Prize for the Environment in 2005.[20]

In 2018, Berhe was selected as part of the inaugural National Academies of Sciences, Engineering, and Medicine New Voices in Sciences, Engineering, and Medicine cohort, as an early career leader working to advance the conversation around key emerging global issues and communicate the evidence base around those challenges.[21]

An advocate for women in science, Berhe is currently a co-Principal Investigator of ADVANCEGeo, which is working to transform the workplace climate of the geosciences to increase retention of women in the field and develop a sustainable model that can be transferred to other scientific domains. Currently, the Earth Science Women’s Network (ESWN), the Association for Women Geoscientists, and the American Geophysical Union (AGU) have partnered to address the issue of sexual harassment in the earth, space and environmental sciences.[22] The program led by Erika Marín-Spiotta and is run with support from a four-year $1.1 million grant from the National Science Foundation.[23]

She currently serves as an advisory board member of 500 Women Scientists, a grassroots organization working to make science open, inclusive, and accessible, and is on the leadership board of the Earth Science Women’s Network.

Now from the TED Talk, firstly the description:

Part 3 of the TED Radio Hour episode What Lies Beneath.

Earth’s soil can store vast amounts of carbon. Biogeochemist Asmeret Asefaw Berhe says soil could be a powerful tool for fighting climate change – if only we stopped treating it like dirt.

About Asmeret Asefaw Berhe

Asmeret Asefaw Berhe is a soil biogeochemist and President Biden’s nominee to lead the Department of Energy Office of Science. She is a professor of soil biogeochemistry at University of California, Merced. Her research group works to understand how soil helps regulate the earth’s climate.

Berhe’s work exists at the intersection of soil, climate change, and political ecology. During her graduate career, she was a member of the working group that produced the Millennium Ecosystem Assessment, which was called for by the United Nations to assess the impact of humans on the environment.

Berhe received a B.Sc. in Soil and Water Conservation at the University of Asmara in Eritrea. She has an M.Sc. in Political Ecology from Michigan State University and a Ph.D. in Biogeochemistry from University of California, Berkeley.

This segment of the TED Radio Hour was produced by Matthew Cloutier and Sylvie Douglis and edited by Rachel Faulkner and Katie Simon. You can follow us on Facebook @TEDRadioHour and email us at TEDRadioHour@npr.org.

Now that positive TED Talk:

We wish Asmeret the very best of fortune in bringing about these changes.

Looking after our dogs in Winter

Erik Oltad has some great advice.

In our case our (remaining) dogs, Oliver and Cleopatra, are able to go outside but still remain on our land. But plenty of dog owners are not in such a privileged position and need to take their dogs on public pavements and the like.

Thus for all you dog owners in that position then Erik’s advice is for you.

Dog care below freezing − how to keep your pet warm and safe from cold weather, road salt and more this winter

Erik Christian Olstad, University of California, Davis

Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can quickly turn chilly and dangerous for people and pups alike.

Winter brings some unique challenges for dog owners, since dogs still need activity and socialization during colder seasons. Studies have shown that dog owners are almost 50% less likely to walk their dogs when the weather gets cold. Knowing the basics of winter safety is critical to maintaining a healthy lifestyle for your dog.

I am an assistant professor at the University of California Davis School of Veterinary Medicine who weathered polar vortexes with my dog while living in Michigan early in my career. While I’ve since moved to sunny California, I’ve seen how quickly frigid temperatures can turn dangerous for pets.

Breed and age differences

Not all dogs have the same abilities to deal with cold weather. A short-coated dog like a Chihuahua is much more susceptible to the dangers of cold weather than a thick-coated husky. When the weather dips below 40 degrees Fahrenheit (4 degrees Celsius), the well-acclimated husky may be comfortable, whereas the Chihuahua would shiver and be at risk of hypothermia.

Additionally, if your dog is used to warm weather, but you decide to move to a colder region, the dog will need time to acclimate to that colder weather, even if they have a thick coat.

Age also affects cold-weather resilience. Puppies and elderly dogs can’t withstand the chill as well as other dogs, but every dog is unique – each may have individual health conditions or physical attributes that make them more or less resilient to cold weather.

When is my dog too cold?

Pet owners should be able to recognize the symptoms of a dog that is getting too cold. Dogs will shiver, and some may vocalize or whine. Dogs may resist putting their feet down on the cold ground, or burrow, or try to find warmth in their environment when they are uncomfortable.

Just like people, dogs can get frostbite. And just like people, the signs can take days to appear, making it hard to assess them in the moment. The most common sites for frostbite in dogs are their ears and the tips of their tails. Some of the initial signs of frostbite are skin discoloring, turning paler than normal, or purple, gray or even black; red, blistered skin; swelling; pain at the site; or ulceration.

Other serious signs of hypothermia include sluggishness or lethargy, and if you observe them, please visit your veterinarian immediately. A good rule to live by is if it is too cold for you, it is too cold for your dog.

Getting your dog a sweater or jacket and paw covers can provide them with protection from the elements and keep them comfortable. Veterinarians also recommend closely monitoring your dog and limiting their time outside when the temperature nears the freezing point or drops below it.

Road salt dangers

Road salt that treats ice on streets and sidewalks can also harm dogs. When dogs walk on the salt, the sharp, rough edges of the salt crystals can irritate the sensitive skin on their paws.

Dogs will often lick their feet when they’re dirty, wet or irritated, and if they ingest any salt doing that, they may face GI upset, dehydration, kidney failure, seizures or even death. Even small amounts of pure salt can disrupt critical body functions in dogs.

Some companies make pet-safe salt, but in public it can be hard to tell what type of salt is on the ground. After walking your dog, wash off their feet or boots. You can also keep their paw fur trimmed to prevent snow from balling up or salt collecting in the fur. Applying a thin layer of petroleum jelly or paw pad balm to the skin of the paw pads can also help protect your pet’s paws from irritation.

Antifreeze risks

Antifreeze, or ethylene glycol, is in most vehicles to prevent the fluids from freezing when it gets cold out. Some people pour antifreeze into their toilets when away from their home to prevent the water in the toilet from freezing.

Antifreeze is an exceptionally dangerous chemical to dogs and cats, as it tastes sweet but can be deadly when ingested. If a pet ingests even a small amount of antifreeze, the substance causes a chemical cascade in their body that results in severe kidney damage. If left untreated, the pet may have permanent kidney damage or die.

There are safer antifreeze options on the market that use ingredients other than ethylene glycol. If your dog ingests antifreeze, please see your veterinarian immediately for treatment.

When temperatures dip below freezing, the best thing pet owners can do is keep the time spent outside as minimal as possible. Try some indoor activities, like hide-and-seek with low-calorie treats, fetch or even an interactive obstacle course. Food puzzles can also keep your dog mentally engaged during indoor time.

Although winter presents some unique challenges, it can still be an enjoyable and healthy time for you and your canine companion.

Erik’s comments about ethylene glycol (EG), or antifreeze as it more commonly known, and the incredible dangers to dogs EG possesses are vital to understand.

Please, please keep your dogs very safe in Winter! If Erik’s advice helps save even a single dog then me republishing this will have been worthwhile.

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.

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.

Please read for yourself.

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.

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.

How to Control and Prevent Common Dog Diseases Effectively

By Luna Angeni

“Man’s best friend” is a phrase that perfectly defines the deep bond between humans and their canine companions.

It’s our duty to ensure the health and well-being of our furry friends. One of the most critical aspects of canine care is disease prevention and control. This is what we are going to focus on here.

In this blog, we will learn about some effective ways we can control and prevent common dog diseases to keep our canine fellows happy and healthy.

Let’s get started!

Understanding Common Dog Diseases

Dogs, like humans, are susceptible to a range of diseases and health issues.

To effectively control and prevent these complications, we need to understand them first.

Let’s review some common canine diseases:

Canine Parvovirus (Parvo)

Canine parvovirus is a highly contagious and potentially fatal disease that affects puppies and unvaccinated dogs.

It spreads through direct contact with an infected dog or contaminated environment.

Symptoms include:

1. Severe diarrhea

2. Vomiting
3. Lethargy
4. Loss of appetite

To prevent parvo, ensure your dog is up-to-date on vaccinations and avoid areas where the virus may be present.

Canine Distemper

Canine distemper is another contagious viral disease that can be fatal, particularly in puppies.

It affects various body systems and presents symptoms such as:

1. Fever
2. Nasal discharge

3. Coughing
4. Neurological signs

Vaccination is the most effective way to prevent distemper.

Heartworm Disease

Heartworm disease is transmitted through mosquito bites and can be life-threatening if left untreated.

It affects the heart and lungs, leading to symptoms like:

1. Coughing
2. Exercise intolerance

3. Weight loss

Prevention through vaccination is key for this common dog disease.

Preventive Measures for Common Canine Diseases

Preventing common dog diseases is often more manageable than treating them.

Here are some essential preventive measures every dog owner should follow:

Vaccination

Regular vaccination is the cornerstone of disease prevention in dogs.

As your veterinarian recommends, ensure your dog receives all necessary vaccinations against parvovirus, distemper, rabies, and others.

Regular Exercise

Exercise not only keeps your dog physically fit but also mentally stimulated.

Engaging in regular exercise helps boost dogs’ overall health and keeps obesity-related diseases at bay.

Proper Nutrition

A balanced diet is crucial for maintaining a healthy immune system.

Consult your veterinarian to determine the best diet for your dog’s specific needs.

Avoid feeding your canine human food, as some ingredients can be toxic to them.

Hygiene and Cleanliness

Maintaining proper hygiene for your dog and their living environment is essential.

In this regard, you must ensure:

1. Regular grooming
2. Cleaning your dog’s bedding
3. Keeping their living area free from parasites and bacteria

Regular Vet Check-ups

Routine visits to the veterinarian are crucial for early disease detection and prevention.

Your vet can identify potential health issues before they become severe and provide guidance on maintaining your dog’s health.

Recognizing the Signs of Illness

Despite your best efforts, your dog may still fall ill occasionally.

Recognizing the early signs of common dog diseases is essential for prompt treatment.

Here are some common signs of complications in dogs:

Changes in Appetite

A sudden loss of appetite or excessive hunger can indicate a health issue.

So, you must monitor your dog’s eating habits closely.

Changes in Behavior

Drastic changes in behavior, such as increased aggression, withdrawal, or excessive vocalization, can be indicative of pain or discomfort.

Vomiting and Diarrhea

Frequent vomiting or diarrhea can be symptomatic of various diseases, including gastrointestinal complications.

Lethargy

If your dog is unusually lethargic or lacks energy, it could be a sign of an underlying problem.

In such cases, seek a veterinarian’s help immediately.

Breathing Problems

Labored breathing, coughing, or wheezing may suggest respiratory or cardiac problems.

Immediate Action and Veterinary Care

Taking immediate action is essential if you notice any signs of illness or discomfort in your dog.

Contact your veterinarian and follow their guidance.

Early intervention can often make a significant difference in the outcome of the disease.

Conclusion

Your dog’s health is in your hands.

Effective disease control and prevention are crucial for ensuring your furry friend’s long and happy life.

Understanding common dog diseases and treatment and following preventive measures can significantly reduce the risk of complications and provide them with the best possible care.

FAQs

What Vaccinations Does My Dog Need?

Consult your vet for a personalized vaccination schedule. Common dog vaccinations include rabies, distemper, parvovirus, and kennel cough.

What’s the Best Diet for My Dog?

High-quality commercial dog food is a good option. Still, you need to consult your vet for a diet tailored to your dog’s age, breed, and health.

How Often Should I Take My Dog to the Vet?

Generally, annual check-ups are recommended, but older dogs can benefit more from biannual visits. And–puppies may need more frequent check-ups.

Picture Parade Four Hundred and Ninety-Seven

Brady!

Let me quote from a post on Ugly Hedgehog because it will make a good introduction to today’s Picture Parade.

We made our way to get a new pup. Before I could get to the litter to choose, one of them decided to walk over to me and sit right between my feet. Clearly he was telling me that he was the one. From the start he was comfortable with anything and anyone around him. No matter what the situation, it was his pleasure and he made it ours. He loved strangers and playmates of all kinds – even taking selfies with them. You could hide his toys anywhere and he had an amazing sense to find them. He was a gentle soul who enriched our hearts for nearly 14 years. Brady surrendered to a medical condition he endured for a couple of years without ever showing an ounce of complaint. Some days its tough to walk without him by my side, but no sympathy is needed because he left us with too much joy. Instead, give your pets the unconditional love they give you for as long as you are so blessed.

There is so much more to our dogs than we realise!

A fascinating post on Treehugger.

It is Wednesday morning in Southern Oregon and already I am having to think about the post for tomorrow. Not that this is a problem it is just one more thing that I want to do. Plus we are in the middle of a local heat wave with temperatures expected to be well above 100 degrees F and possibly 109 deg F (42.8 deg C.).

So I am turning to Treehugger for a dog post and hoping that I shall be able to share it with you all.

Dogs Could Revolutionize the Sustainability of Future Pandemic Testing

Scent dogs are quicker, more effective, and create less healthcare waste than conventional COVID tests.

One of the more frustrating roadblocks in navigating the COVID-19 pandemic was the difficulty in getting quick, accurate test results. Sometimes, results for PCR tests took up to two weeks, rendering their diagnosis useless for planning isolation scenarios. Meanwhile, rapid tests still oftentimes provide a false negative if taken too soon after infection. When I had COVID, I was four days into symptoms before I got a positive at-home test—I’ve heard many people recount similar stories.

The testing we have is certainly better than nothing, but it leaves a lot to be desired. If only there were a better way, say, using something with remarkable innate sensitivity. Like, dogs. Far-fetched? Not at all.

A review of recent research concluded that scent dogs may represent a cheaper, faster, and more effective way to detect COVID-19 and could be a key tool in future pandemics. This could be a game-changer for sustainability as well, eliminating the enormous amount of waste that comes with billions of testing kits.

The review, published in De Gruyter’s Journal of Osteopathic Medicine, found that scent dogs are as effective, or even more effective, than conventional COVID-19 tests such as PCR tests.

Most of us know that dogs have a remarkable sense of smell; they sniff out drugs and explosives and have even successfully identified patients with certain cancers, Parkinson’s, and diabetes. They have up to 300 million olfactory cells, compared to 5 or 6 million in humans. And they use one-third of their brains to process scent information—humans just use 5%.

Professor Tommy Dickey of the University of California, Santa Barbara, and Heather Junqueira of BioScent Detection Dogs analyzed 29 different studies in which dogs detected COVID-19. “The studies were performed using over 31,000 samples by over 400 scientists from more than 30 countries using 19 different dog breeds. In some studies, the scent dogs sniffed people directly, sometimes in public places as a health screening. In others, the dogs sniffed patient samples such as sweat, saliva, or urine samples,” explains a press statement from De Gruyter.

Dogs’ Incredible Accuracy 

The dogs ranged from Labrador retrievers and Belgian malinois to beagles and English springer spaniels. In most of the studies, the dogs demonstrated similar or better sensitivity and specificity than the current gold-standard PCR tests or antigen tests.

“In one study, four of the dogs could detect the equivalent of less than 2.6 x 10−12 copies of viral RNA per milliliter. This is equivalent to detecting one drop of any odorous substance dissolved in ten and a half Olympic-sized swimming pools and is three orders of magnitude better than modern scientific instruments,” notes De Gruyter.

Remarkably, they not only detected COVID-19 in symptomatic, pre-symptomatic, and asymptomatic patients, but they could also sniff out COVID variants and even long COVID.

Considering the Safety of the Dogs 

One thing we certainly don’t want is for dogs to become collateral damage in the pursuit of better testing. The study authors acknowledge this, writing that the “safety of scent dogs, their handlers, and those who are inspected by the dogs is critical for the acceptance and implementation of the scent dog screening and testing approach.”

“This is consistent with the One Health paradigm,” they add, “which defines health as more than the absence of disease and recognizes the interrelationships among humans, animals, and environmental welfare.”

The authors evaluated whether medical detection dogs could contract and become ill with the COVID-19 virus and if dogs pass on the COVID-19 virus to humans. From a number of studies, they concluded that dogs are in the low-risk category. “To our knowledge, there have been no deaths of dogs that can be unequivocally attributed to COVID-19,” the authors explain. “Importantly, the studies described above suggest that it is safe for healthy individual handlers to utilize scent dogs to directly screen and test individuals who may be infected with the COVID-19 virus.”

Speedy Test Results 

A major benefit of using the dogs is their speed. In one study, researchers were able to do a lineup with 40 samples, including sample collection, lineup loading, and unloading, within just 3  minutes.

“The time between RT-PCR sampling and the return of results can be up to days, whereas the RAG test results are obtained within about 15 min.,” write the study authors. “Again, if scent dogs directly sniff individuals, results are learned in seconds, or a few minutes if samples are taken and sniffed soon after by the dogs.”

“The criticality of the speed of the return of test results cannot be overemphasized,” the authors add.

Elimination of Plastic Waste 

That dogs could provide a result in seconds to minutes is crucial. But additionally, and importantly, scent tests by dogs don’t require expensive lab equipment or create mountains of plastic waste, unlike conventional diagnostic approaches.

As of December 22, 2022, the United States alone had performed around 1.15 billion tests for COVID-19. Thinking of all the material for the testing kits and all the resources used for testing labs and sending samples around, etc., the reduction in ecological footprint is potentially tremendous.

Not to mention the cost. Some of the research in the review was, in fact, motivated by the need for inexpensive testing in developing nations, the authors note.

“Although many people have heard about the exceptional abilities of dogs to help humans, their value to the medical field has been considered fascinating, but not ready for real-world medical use,” says Dickey. “Having conducted this review, we believe that scent dogs deserve their place as a serious diagnostic methodology that could be particularly useful during pandemics, potentially as part of rapid health screenings in public spaces. We are confident that scent dogs will be useful in detecting a wide variety of diseases in the future.”

In the interests of expanding the argument, here is a copy of a comment left to that original post:

Here we go again, using animals for testing. I believe that dogs can’t smell covid and detected it 100%, but we humans NEVER treat animals with the respect and equality they deserve, so I am very concern for the safety and health of testing “smell Covid” dogs… I know a person that have esophageal cancer and for almost 5 years before it was diagnosed, his dog (an adorable mutt) insisted on crawling over her owner chest every single time that he laid down, in an attempt to “cure” the inflammation in that spot. After the cancer was eliminated with chemo and surgery the dog stopped doing it… 
I which we humans were more connected and attentive with animal wisdom, to learn from them, respecting and became better people.

I think that second sentence should read can smell covid but have left it how it was printed.

Anyway, I will leave readers to cover the main article which speaks very highly of man’s best friend.

These Heat Waves?

What is the truth?

Today, August 14th, here in Southern Oregon we are expecting 111 degrees Fahrenheit or 43.8 degrees C. That is really hot! (And at home it reached 108 deg. F. at 3pm.)

So it seems pertinent to republish a post from The Conversation that was published on July 21st, 2023.

Is it really hotter now than any time in 100,000 years?

By Darrell Kaufman

Professor of Earth and Environmental Sciences, Northern Arizona University

As scorching heat grips large swaths of the Earth, a lot of people are trying to put the extreme temperatures into context and asking: When was it ever this hot before?

Globally, 2023 has seen some of the hottest days in modern measurements, but what about farther back, before weather stations and satellites?

Some news outlets have reported that daily temperatures hit a 100,000-year high. 

As a paleoclimate scientist who studies temperatures of the past, I see where this claim comes from, but I cringe at the inexact headlines. While this claim may well be correct, there are no detailed temperature records extending back 100,000 years, so we don’t know for sure.

Here’s what we can confidently say about when Earth was last this hot.

This is a new climate state

Scientists concluded a few years ago that Earth had entered a new climate state not seen in more than 100,000 years. As fellow climate scientist Nick McKay and I recently discussed in a scientific journal article, that conclusion was part of a climate assessment report published by the Intergovernmental Panel on Climate Change (IPCC) in 2021.

Earth was already more than 1 degree Celsius (1.8 Fahrenheit) warmer than preindustrial times, and the levels of greenhouse gases in the atmosphere were high enough to assure temperatures would stay elevated for a long time.

Earth’s average temperature has exceeded 1 degree Celsius (1.8 F) above the preindustrial baseline. This new climate state will very likely persist for centuries as the warmest period in more than 100,000 years. The chart shows different reconstructions of temperature over time, with measured temperatures since 1850 and a projection to 2300 based on an intermediate emissions scenario. D.S. Kaufman and N.P. McKay, 2022, and published datasets, Author provided

Even under the most optimistic scenarios of the future – in which humans stop burning fossil fuels and reduce other greenhouse gas emissions – average global temperature will very likely remain at least 1 C above preindustrial temperatures, and possibly much higher, for multiple centuries.

This new climate state, characterized by a multi-century global warming level of 1 C and higher, can be reliably compared with temperature reconstructions from the very distant past.

How we estimate past temperature

To reconstruct temperatures from times before thermometers, paleoclimate scientists rely on information stored in a variety of natural archives.

The most widespread archive going back many thousands of years is at the bottom of lakes and oceans, where an assortment of biological, chemical and physical evidence offers clues to the past. These materials build up continuously over time and can be analyzed by extracting a sediment core from the lake bed or ocean floor.

These sediment-based records are rich sources of information that have enabled paleoclimate scientists to reconstruct past global temperatures, but they have important limitations.

For one, bottom currents and burrowing organisms can mix the sediment, blurring any short-term temperature spikes. For another, the timeline for each record is not known precisely, so when multiple records are averaged together to estimate past global temperature, fine-scale fluctuations can be canceled out.

Because of this, paleoclimate scientists are reluctant to compare the long-term record of past temperature with short-term extremes.

Looking back tens of thousands of years

Earth’s average global temperature has fluctuated between glacial and interglacial conditions in cycles lasting around 100,000 years, driven largely by slow and predictable changes in Earth’s orbit with attendant changes in greenhouse gas concentrations in the atmosphere. We are currently in an interglacial period that began around 12,000 years ago as ice sheets retreated and greenhouse gases rose.

Looking at that 12,000-year interglacial period, global temperature averaged over multiple centuries might have peaked roughly around 6,000 years ago, but probably did not exceed the 1 C global warming level at that point, according to the IPCC report. Another study found that global average temperatures continued to increase across the interglacial period. This is a topic of active research.

That means we have to look farther back to find a time that might have been as warm as today.

The last glacial episode lasted nearly 100,000 years. There is no evidence that long-term global temperatures reached the preindustrial baseline anytime during that period.

If we look even farther back, to the previous interglacial period, which peaked around 125,000 years ago, we do find evidence of warmer temperatures. The evidence suggests the long-term average temperature was probably no more than 1.5 C (2.7 F) above preindustrial levels – not much more than the current global warming level.

Now what?

Without rapid and sustained reductions in greenhouse gas emissions, the Earth is currently on course to reach temperatures of roughly 3 C (5.4 F) above preindustrial levels by the end of the century, and possibly quite a bit higher.

At that point, we would need to look back millions of years to find a climate state with temperatures as hot. That would take us back to the previous geologic epoch, the Pliocene, when the Earth’s climate was a distant relative of the one that sustained the rise of agriculture and civilization.

It is difficult to know what to say other than one hopes that Governments and country leaders recognise the situation and DO SOMETHING!

As Dr. Michael Mann put it in the last issue of The Humanist: “The only obstacles aren’t the laws of physics, but the flaws in our politics.“

I have a son and a daughter in their early 50’s and a grandson who is 12. They, along with millions of other younger people, need action now.

Please!
