For most dogs, their friend groups usually consist of a mix of humans and other dogs. But Lili, a 3-year-old dog who lives on a French Polynesian atoll called Fakarava, isn’t like most other dogs. She prefers friends who have gills and fins. In fact, her very best friend is a shark.
Ever since Lili’s mom, Emmanuelle Larchet, adopted Lili, she’s known that her dog has an affinity for all things aquatic. She started swimming in the lagoon near Larchet’s house when she was only a month old.
“She’s really a water dog,” Larchet told The Dodo.
There are around 100 sharks who live in this lagoon near Larchet’s house. So when Lili swims in the water there, she’s surrounded by them. While many dog parents would be terrified to see their dog swimming amongst sharks, Larchet knows that the sharks Lili swims with are nurse sharks, who are actually very docile creatures.
“We call them sea puppies because [they’re] like dogs, actually … They are very nice,” Larchet said.
Larchet likes to joke that when Lili swims around with her shark friends, it’s sea puppies meeting earth puppies.
Over the years Lili has been swimming in the lagoon, there’s one shark in particular she’s grown especially close with. His name is Sharky, and he and Lili visit each other almost every day. Larchet and Lili are able to recognize Sharky because he has a special marking on one of his fins.
Lili and Sharky like to explore their lagoon together. They enjoy splashing around in the warm, clear water.
“He comes to say hello every time she sees him,” Larchet said.
Even though Lili and Larchet are best friends themselves, Larchet is more than happy to share her Lili with Sharky. And even though Larchet watches Lili hang out with her shark friends all the time, it never gets old seeing them spend time together.
“[When] I see her swimming with Sharky, [I’m] so happy,” Larchet said.
Ellie Woods’ family dog Bobby has always been an important part of her love story with her wife Georgie Woods. When Ellie brought Georgie home for the first time, the family member she was most anxious for Georgie to meet was Bobby.
When the couple got engaged and started planning their wedding, they decided it would be fun to try to document the wedding from Bobby’s unique perspective. So right before the ceremony started, they attached a GoPro to Bobby’s back and then set him loose.
For some dogs, walking around with a camera on their back might take some getting used to — but not for Bobby. He immediately felt comfortable.
“He loves being the center of attention,” Georgie told The Dodo. “He just loved it.”
Georgie and Ellie said having Bobby at their wedding was incredibly meaningful for them.
@SASHALEEPHOTOGRAPHY
“Animals are really important to queer couples,” Ellie said. “[I]t was so important to have him … as part of our big day.
When the newlyweds sat down to watch the footage Bobby had captured, what they saw surprised and delighted them. The GoPro had caught Bobby stealing hors d’oeuvres and even walking in on Georgie’s sister in the bathroom. While Bobby is an expert videographer, he is still a dog, after all.
Of course, Bobby’s camera recorded much more than shenanigans. Georgie and Ellie loved watching themselves walk down the aisle together from Bobby’s perspective.
“It captured some really special moments,” Ellie said. “[W]e couldn’t be happier for how it came out because it’s just so organic and such an interesting, different perspective.”

Dogs are just incredible. As much as I have already said that, time and time again there comes a story that just reinforces that previous sentence.
Extreme weather is by definition rare on our planet. Ferocious storms, searing heatwaves and biting cold snaps illustrate what the climate is capable of at its worst. However, since Earth’s climate is rapidly warming, predominantly due to fossil fuel burning, the range of possible weather conditions, including extremes, is changing.
Scientists define “climate” as the distribution of possible weather events observed over a length of time, such as the range of temperatures, rainfall totals or hours of sunshine. From this they construct statistical measures, such as the average (or normal) temperature. Weather varies on several timescales – from seconds to decades – so the longer the period over which the climate is analysed, the more accurately these analyses capture the infinite range of possible configurations of the atmosphere.
Typically, meteorologists and climate scientists use a 30-year period to represent the climate, which is updated every ten years. The most recent climate period is 1991-2020. The difference between each successive 30-year climate period serves as a very literal record of climate change.
This way of thinking about the climate falls short when the climate itself is rapidly changing. Global average temperatures have increased at around 0.2°C per decade over the past 30 years, meaning that the global climate of 1991 was around 0.6°C cooler than that in 2020 (when accounting for other year-to-year fluctuations), and even more so than the present day.
A moving target for climate modellers
If the climate is a range of possible weather events, then this rapid change has two implications. First, it means that part of the distribution of weather events comprising a 30-year climate period occurred in a very different background global climate: for example, northerly winds in the 1990s were much colder than those in the 2020s in north-west Europe, thanks to the Arctic warming nearly four times faster than the global average. Statistics from three decades ago no longer represent what is possible in the present day.
Second, the rapidly changing climate means we have not necessarily experienced the extremes that modern-day atmospheric and oceanic warmth can produce. In a stable climate, scientists would have multiple decades for the atmosphere to get into its various configurations and drive extreme events, such as heatwaves, floods or droughts. We could then use these observations to build up an understanding of what the climate is capable of. But in our rapidly changing climate, we effectively have only a few years – not enough to experience everything the climate has to offer.
Extreme weather events require what meteorologists might call a “perfect storm”. For example, extreme heat in the UK typically requires the northward movement of an air mass from Africa combined with clear skies, dry soils and a stable atmosphere to prevent thunderstorms forming which tend to dissipate heat.
Such “perfect” conditions are intrinsically unlikely, and many years can pass without them occurring – all while the climate continues to change in the background. Based on an understanding of observations alone, this can leave us woefully underprepared for what the climate can now do, should the right weather conditions all come together at once.
Startling recent examples include the extreme heatwave in the Pacific north-west of North America in 2021, in which temperatures exceeded the previous Canadian record maximum by 4.6°C. Another is the occurrence of 40°C in the UK in summer 2022, which exceeded the previous UK record maximum set only three years earlier by 1.6°C. This is part of the reason why the true impact of a fixed amount of global warming is only evident after several decades, but of course – since the climate is changing rapidly – we cannot use this method anymore.
Playing with fire
To better understand these extremes, scientists can use ensembles: many runs of the same weather or climate model that each slightly differ to show a range of plausible outcomes. Ensembles are routinely used in weather prediction, but can also be used to assess extreme events which could happen even if they do not actually happen at the time.
When 40°C first appeared in ensemble forecasts for the UK before the July 2022 heatwave, it revealed the kind of extreme weather that is possible in the current climate. Even if it had not come to fruition, its mere appearance in the models showed that the previously unthinkable was now possible. In the event, several naturally occurring atmospheric factors combined with background climate warming to generate the record-shattering heat on July 19 that year.
The highest observed temperature each year in the UK, from 1900 to 2023
Later in summer 2022, after the first occurrence of 40°C, some ensemble weather forecasts for the UK showed a situation in which 40°C could be reached on multiple consecutive days. This would have posed an unprecedented threat to public health and infrastructure in the UK. Unlike the previous month, this event did not come to pass, and was quickly forgotten – but it shouldn’t have been.
It is not certain whether these model simulations correctly represent the processes involved in producing extreme heat. Even so, we must heed the warning signs.
Despite a record-warm planet, summer 2024 in the UK has been relatively cool so far. The past two years have seen global temperatures far above anything previously observed, and so potential extremes have probably shifted even further from what we have so far experienced.
Just as was the case in August 2022, we’ve got away with it for now – but we might not be so lucky next time.
That last sentence says it all: “Just as was the case in August 2022, we’ve got away with it for now – but we might not be so lucky next time.”
I am giving a talk, The Next Ten Years, next Saturday to our local Freethinkers group in Grants Pass. Close to the start of the presentation I say: “The Global Temperature anomaly, as of last year, 2023, is 1.17 C, 2.11 F, above the long-term average from 1951 to 1980. The 10 most recent years are the warmest years on record.“
Finally, I am getting on in age and part of me wants to die, hopefully naturally, before more climate extremes are reached, but then another part of me would like to experience it!

It’s thought to be the work of Francis Darwin, the seventh child of British naturalist Charles Darwin and his wife, Emma, and appears to have been made in 1857, when Frank would have been 10 or 11. And it’s drawn on the back of a page of a draft of “On the Origin of Species,” Darwin’s masterwork and the foundational text of evolutionary biology. The few sheets of the draft that survive are pages Darwin gave to his children to use for drawing paper.
Darwin’s biographers have long recognized that play was important in his personal and familial life. The Georgian manor in which he and Emma raised their 10 children was furnished with a rope swing hung over the first-floor landing and a portable wooden slide that could be laid over the main stairway. The gardens and surrounding countryside served as an open-air laboratory and playground.
Play also has a role in Darwin’s theory of natural selection. As I explain in my new book, “Kingdom of Play: What Ball-bouncing Octopuses, Belly-flopping Monkeys, and Mud-sliding Elephants Reveal about Life Itself,” there are many similarities – so many that if you could distill the processes of natural selection into a single behavior, that behavior would be play.
Through natural selection, the rock pocket mouse has evolved a coat color that hides it from predators in the desert Southwest.
In contrast to foraging and hunting – behaviors with clearly defined goals – play is likewise undirected. When a pony frolics in a field, a dog wrestles with a stick or chimpanzees chase each other, they act with no goal in mind.
Natural selection is utterly provisional: The evolution of any organism responds to whatever conditions are present at a given place and time. Likewise, animals at play are acting provisionally. They constantly adjust their movements in response to changes in circumstances. Playing squirrels, faced with obstacles such as falling branches or other squirrels, nimbly alter their tactics and routes.
Natural selection is open-ended. The forms of life are not fixed, but continually evolving. Play, too, is open-ended. Animals begin a play session with no plan of when to end it. Two dogs play-fighting, for instance, cease playing only when one is injured, exhausted or simply loses interest.
Keepers noticed that Shanthi, a 36-year-old elephant at the Smithsonian national zoo, liked to make noise with objects, so they gave her horns, harmonicas and other noisemakers.
Play is likewise profligate. It requires an animal to expend time and energy that perhaps would be better devoted to behaviors such as foraging and hunting that could aid survival.
And that profligacy is also advantageous. Animals forage and hunt in specific ways that don’t typically change. But an animal at play is far more likely to innovate – and some of its innovations may in time be adapted into new ways to forage and hunt.
Competing and cooperating
As Darwin first framed it, the “struggle for existence” was by and large a competition. But in the 1860s, Russian naturalist Pyotr Kropotkin’s observations of birds and fallow deer led him to conclude that many species were “the most numerous and the most prosperous” because natural selection also selects for cooperation.
Scientists confirmed Kroptokin’s hypothesis in the 20th century, discovering all manner of cooperation, not only between members of the same species but between members of different species. For example, clown fish are immune to anemone stings; they nestle in anemone tentacles for protection and, in return, keep the anemones free of parasites, provide nutrients and drive away predators.
Play likewise utilizes both competition and cooperation. Two dogs play-fighting are certainly competing, yet to sustain their play, they must cooperate. They often reverse roles: A dog with the advantage of position might suddenly surrender that advantage and roll over on its back. If one bites harder than intended, it is likely to retreat and perform a play bow – saying, in effect, “My bad. I hope we can keep playing.”
River otters at the Oregon Zoo repeatedly separate and reunite while playing in a tub of ice.
Natural selection and play also may both employ deception. From butterflies colored to resemble toxic species to wild cats that squeal like distressed baby monkeys, many organisms use mimicry to deceive their prey, predators and rivals. Play – specifically, play-fighting – similarly offers animals opportunities to learn about and practice deception.
And since natural selection shares so many features with play, we may with some justification maintain that life, in a most fundamental sense, is playful.
Before I share the article with you, I felt I should mention that I haven’t found a link to share the Live Science item and it may need to be moved. We will see what happens.

Dogs can smell their humans’ stress, and it makes them sad.
Dogs can smell when people are stressed, and it seems to make them feel downhearted.
A new study shows that dogs pick up on our emotions through their sense of smell. (Image credit: Catherine Falls Commercial via Getty Images)
Humans and dogs have been close companions for perhaps 30,000 years, according to anthropological and DNA evidence. So it would make sense that dogs would be uniquely qualified to interpret human emotion. They have evolved to read verbal and visual cues from their owners, and previous research has shown that with their acute sense of smell, they can even detect the odor of stress in human sweat. Now researchers have found that not only can dogs smell stress—in this case represented by higher levels of the hormone cortisol—they also react to it emotionally.
For the new study, published Monday in Scientific Reports, scientists at the University of Bristol in England recruited 18 dogs of varying breeds, along with their owners. Eleven volunteers who were unfamiliar to the dogs were put through a stress test involving public speaking and arithmetic while samples of their underarm sweat were gathered on pieces of cloth. Next, the human participants underwent a relaxation exercise that included watching a nature video on a beanbag chair under dim lighting, after which new sweat samples were taken. Sweat samples from three of these volunteers were used in the study.
Participating canines were put into three groups and smelled sweat samples from one of the three volunteers. Prior to doing so, the dogs were trained to know that a food bowl at one location contained a treat and that a bowl at another location did not. During testing, bowls that did not contain a treat were sometimes placed in one of three “ambiguous” locations. In one testing session, when the dogs smelled the sample from a stressed volunteer, compared with the scent of a cloth without a sample, they were less likely to approach the bowl in one of the ambiguous locations, suggesting that they thought this bowl did not contain a treat. Previous research has shown that an expectation of a negative outcome reflects a down mood in dogs.
The results imply that when dogs are around stressed individuals, they’re more pessimistic about uncertain situations, whereas proximity to people with the relaxed odor does not have this effect, says Zoe Parr-Cortes, lead study author and a Ph.D. student at Bristol Veterinary School at the University of Bristol. “For thousands of years, dogs have learned to live with us, and a lot of their evolution has been alongside us. Both humans and dogs are social animals, and there’s an emotional contagion between us,” she says. “Being able to sense stress from another member of the pack was likely beneficial because it alerted them of a threat that another member of the group had already detected.”
The fact that the odor came from an individual who was unfamiliar to the dogs speaks to the importance of smell for the animals and to the way it affects emotions in such practical situations, says Katherine A. Houpt, a professor emeritus of behavioral medicine at Cornell University’s College of Veterinary Medicine. Houpt, who was not involved in the new study, suggests that the smell of stress may have reduced the dogs’ hunger because it’s known to impact appetite. “It might not be that it’s changing their decision-making but more that it’s changing their motivation for food,” she says. “It makes sense because when you’re super stressed, you’re not quite as interested in that candy bar.”
This research, Houpt adds, shows that dogs have empathy based on smell in addition to visual and verbal cues. And when you’re stressed, that could translate into behaviors that your dog doesn’t normally display, she says. What’s more, it leaves us to wonder how stress impacts the animals under the more intense weight of an anxious owner. “If the dogs are responding to more mild stress like this, I’d be interested to see how they responded to something more serious like an impending tornado, losing your job or failing a test,” Houpt says. “One would expect the dog to be even more attuned to an actual threat.”

Dogs are such perfect animals and Sara brings this out so well. As was pointed out in the article dogs have learned to live with us humans over thousands of years.
Until quite recently I had imagined that a tree was just a tree. Then Jean and I got to watch a YouTube video on trees and it blew our minds. Here is what we watched:
That led us on to watching Judi Dench’s video of trees:
Which is a longish introduction to a piece on The Conversation about trees.

Trees don’t like to breathe wildfire smoke, either – and they’ll hold their breath to avoid it
When wildfire smoke is in the air, doctors urge people to stay indoors to avoid breathing in harmful particles and gases. But what happens to trees and other plants that can’t escape from the smoke?
They respond a bit like us, it turns out: Some trees essentially shut their windows and doors and hold their breath.
As atmospheric and chemical scientists, we study the air quality and ecological effects of wildfire smoke and other pollutants. In a study that started quite by accident when smoke overwhelmed our research site in Colorado, we were able to watch in real time how the leaves of living pine trees responded.
How plants breathe
Plants have pores on the surface of their leaves called stomata. These pores are much like our mouths, except that while we inhale oxygen and exhale carbon dioxide, plants inhale carbon dioxide and exhale oxygen.
Both humans and plants inhale other chemicals in the air around them and exhale chemicals produced inside them – coffee breath for some people, pine scents for some trees.
Unlike humans, however, leaves breathe in and out at the same time, constantly taking in and releasing atmospheric gases.
Clues from over a century of research
In the early 1900s, scientists studying trees in heavily polluted areas discovered that those chronically exposed to pollution from coal-burning had black granules clogging the leaf pores through which plants breathe. They suspected that the substance in these granules was partly created by the trees, but due to the lack of available instruments at the time, the chemistry of those granules was never explored, nor were the effects on the plants’ photosynthesis.
For example, a study of multiple crop and wetland sites in California showed that smoke scatters light in a way that made plants more efficient at photosynthesis and growth. However, a lab study in which plants were exposed to artificial smoke found that plant productivity dropped during and after smoke exposure – though those plants did recover after a few hours.
There are other clues that wildfire smoke can impact plants in negative ways. You may have even tasted one: When grapes are exposed to smoke, their wine can be tainted.
What makes smoke toxic, even far from the fire
When wildfire smoke travels long distances, the smoke cooks in sunlight and chemically changes.
Mixing volatile organic compounds, nitrogen oxides and sunlight will make ground-level ozone, which can cause breathing problems in humans. It can also damage plants by degrading the leaf surface, oxidizing plant tissue and slowing photosynthesis.
While scientists usually think about urban regions as being large sources of ozone that effect crops downwind, wildfire smoke is an emerging concern. Other compounds, including nitrogen oxides, can also harm plants and reduce photosynthesis.
Taken together, studies suggest that wildfire smoke interacts with plants, but in poorly understood ways. This lack of research is driven by the fact that studying smoke effects on the leaves of living plants in the wild is hard: Wildfires are hard to predict, and it can be unsafe to be in smoky conditions.
Accidental research – in the middle of a wildfire
We didn’t set out to study plant responses to wildfire smoke. Instead, we were trying to understand how plants emit volatile organic compounds – the chemicals that make forests smell like a forest, but also impact air quality and can even change clouds.
Fall 2020 was a bad season for wildfires in the western U.S., and thick smoke came through a field site where we were working in the Rocky Mountains of Colorado.
On the first morning of heavy smoke, we did our usual test to measure leaf-level photosynthesis of Ponderosa pines. We were surprised to discover that the tree’s pores were completely closed and photosynthesis was nearly zero.
We also measured the leaves’ emissions of their usual volatile organic compounds and found very low readings. This meant that the leaves weren’t “breathing” – they weren’t inhaling the carbon dioxide they need to grow and weren’t exhaling the chemicals they usually release.

With these unexpected results, we decided to try to force photosynthesis and see if we could “defibrillate” the leaf into its normal rhythm. By changing the leaf’s temperature and humidity, we cleared the leaf’s “airways” and saw a sudden improvement in photosynthesis and a burst of volatile organic compounds.
What our months of data told us is that some plants respond to heavy bouts of wildfire smoke by shutting down their exchange with outside air. They are effectively holding their breath, but not before they have been exposed to the smoke.
We hypothesize a few processes that could have caused leaves to close their pores: Smoke particles could coat the leaves, creating a layer that prevents the pores from opening. Smoke could also enter the leaves and clog their pores, keeping them sticky. Or the leaves could physically respond to the first signs of smoke and close their pores before they get the worst of it.
It’s likely a combination of these and other responses.
The long-term impact is still unknown
The jury is still out on exactly how long the effects of wildfire smoke last and how repeated smoke events will affect plants – including trees and crops – over the long term.

Protein discovery linked to Parkinson’s disease opens future research areas
by WEHI

Parkinson’s disease is the world’s fastest growing neurological condition. Currently there are no drugs or therapies that slow or stop the progression of the disease.
In Australia, someone is diagnosed with Parkinson’s approximately every 30 minutes. Current estimates show there are more than 219,000 people living with Parkinson’s in Australia, a number forecast to double in the next 15 years.
WEHI’s Parkinson’s Disease Research Center has some of the world’s leading researchers tackling the problem using a multi-disciplinary collaborative approach.
New proteins linked to Parkinson’s pathway
Mitochondria are the energy generating machines in our cells and are kept healthy by mitophagy, which is the molecular process of removing or recycling damaged or dysfunctional mitochondria.
PINK1 and Parkin are two key genes involved in mitophagy, and mutations in these genes are linked to early-onset Parkinson’s disease.
Until the discovery of two proteins, NAP1 and SINTBAD, exactly how PINK1/Parkin mitophagy activation was regulated was unknown.

We live just outside Merlin in Southern Oregon. We have 13 acres of which roughly half is wooded. With the year-on-year warming wildfires are never far from our minds during our Summer. Here’s a part of a message from OPB.
What’s happening
High temperatures are in the forecast along the Interstate 5 corridor, the Willamette Valley and in Central and Eastern Oregon. More than a quarter million acres across multiple counties in Eastern Oregon are ablaze with wildfires, and that could mean smoke and haze, especially in Central and northeastern Oregon.

Hot weather persists
The National Weather Service is anticipating a hot weekend across much of Oregon and Southwest Washington. The agency on Friday issued a heat advisory along the Interstate 5 corridor from Battle Ground, Washington to Cottage Grove, Oregon from 11 a.m. to 11 p.m. Saturday. Temperatures could reach the mid-90s.
From central Oregon east towards Burns a heat advisory is in place from 11 a.m. Saturday to 11 p.m. Monday. Harney County could see temperatures over 100 degrees over the weekend.
Which neatly serves as an introduction to an article from The Conversation about protecting one’s home.

How to protect your home from wildfires – here’s what fire prevention experts say is most important
We research wildfire risk to homes and communities. Here’s what decades of research suggest homeowners in high-fire-risk areas can do to protect their properties.
This house near Cle Elum, Wash., survived a 2012 wildfire because of the defensible space around the structure, including a lack of trees and brush close to the house, according to state officials. AP Photo/Elaine Thompson
Small improvements make big differences
A structure’s flammability depends on both the materials that were used to build it and the design of the building. In general, the vulnerability of a house is determined by its weakest point.
The roof, windows, siding and vents are all vulnerable points to pay attention to.
Roof: The roof provides a landing pad where airborne embers can accumulate like snowflakes. Roofs with lots of valleys can collect pine needles and leaves, which can be ignited by flying embers. This is why it’s important for the roof itself to be made of Class A non-flammable material like clay tiles or asphalt shingles, and why roof maintenance, including cleaning gutters, is important. Embers can easily find their way under peeling shingles, through gaps of clay tiles, or into gutters where pine needles and leaves can accumulate.
Windows: If windows are exposed to heat, they can shatter and allow fire inside the home, where curtains can easily ignite. Even double-paned windows can be shattered by the heat of a burning shed 30 feet away, unless the window glass is tempered, making it stronger. Fire-resistant shutters made of metal, if closed before a fire arrives, can offer additional protection. https://www.youtube.com/embed/HjA9yLP1icg?wmode=transparent&start=0 A life-size test with blowing embers at IBHS’s fire lab shows ways homes are at risk form a nearby fire.
Siding: Materials like stucco are non-flammable, while cedar shake siding will burn. Your exterior siding should be non-flammable, but the siding is only as strong as its weakest point. If there are holes in the siding, plug them with caulk to prevent embers from reaching the wooden frame in your walls. Ideally, there will be a 6- to 12-inch concrete foundation between the ground and the bottom of your siding material.
Vents: Reducing risk from vents is easy and affordable and can drastically reduce the flammability of your home. Make sure that one-eighth inch or finer metal mesh is installed over all vents to keep embers out of your attic and your home’s interior.
Controlling your home ignition zone
A home’s vulnerability also depends on the area around it, referred to as the home ignition zone.
The risk in your home ignition zone depends on things such as the slope of your land and the ecosystem surrounding your home. Here are a few guidelines the National Fire Protection Association recommends, both to reduce the chance of flames reaching your home and make it easier for firefighters to defend it.
Zone 1 – Within 5 feet
From the home’s exterior to 5 feet away, you want to prevent flames from coming in contact with windows, siding, vents and eaves. The gold standard is to have only non-flammable material in Zone 1.
The most common risks are having flammable mulch, plants, firewood, lawn furniture, decks and fences. These items have been a primary reason homes burned in many wildfires, including the 2018 Camp Fire that destroyed much of Paradise, California, and the 2012 Waldo Canyon Fire near Colorado Springs, Colorado.

Replacing mulch with gravel or pavers and having only short, sparse plants that don’t touch the house can help reduce the risk.
Wooden decks and fences can burn even if they are well-maintained. Replacing them with non-flammable materials or installing a thin sheet of metal on the house where the siding touches a wooden deck or fence can help protect the home. Mesh screens can prevent the accumulation of debris and embers under the deck.
Zone 2 – 5 to 30 feet away
In the next ring, between 5 and 30 feet from the home, the lawn should be green and short. This is Zone 2.
Be sure to rake up pine needles and leaves and take care to prune the lowest tree branches at least 6 feet high.
There should be about 18 feet of space between trees on a flat slope, and the spacing should increase with slope because steeper terrain drives faster, more intense fires. Walks, pathways, patios, decks and firewood can be kept in this zone.
Zone 3 – 30 to 100 feet away
Beyond Zone 2 and out to about 100 feet from the home is Zone 3. In this area, be sure to give sheds and propane tanks their own defensible space, just like around the house, and prune all low branches to 6 feet.
You can contact your local emergency management office or community wildfire nonprofit to learn more about grant funding that can offset the costs of pruning and removing trees on a forested property.
Beyond 100 feet may extend past your property boundary, but the adjacent house can still be fuel for a wildfire. That’s why it’s smart to plan with your neighbors as you’re reinforcing your own home. Once one house catches fire, house-to-house fire spread is facilitated by closer distances between buildings.
Where we live is beautiful and earlier this year we had a great deal of rain. But the summers are dry; that is a function of the climate in this part of the world. So for July so far we have had no rain and that is normal. Also no rain in July in 2023.
The three zones, as described earlier in this post, are very helpful.
Today’s post is a short video that has no sound. But don’t let that stop you from watching it.
Blind man and dog rescued after days stuck on trail.
A 55-year-old blind man and his dog have been rescued from the Rogue River trail in South-Western Oregon. They began hiking on the trail on July 3 or 4 with a friend. During the hike, the man began to experience heat exhaustion, so the friend left to try to call emergency services. A US Coast Guard helicopter crew airlifted them to safety and the man and his dog were taken to emergency medical services.
My understanding is that they were rescued on July 11th, just a week ago.
I shall be 80 in November; I was born in London some six months before the end of World War II in Europe. I was the result of an affair between my father, Frederick, and my mother, Elizabeth. My father died in December, 1956 when I had recently become twelve years old.
I think that age spans have their own characteristics. So, for example, a person in their 20’s or their 40’s cannot sense what it is like to be in their 70’s or 80’s. Just a theory of mine and I have no evidence that this is a fact.
But as an introduction to today’s post it serves the task perfectly. And today’s post comes from The Conversation.
(And when I was writing this on the 11th July Biden was still the US President. My hunch is that he will not be by the 16th!)

President Joe Biden’s current fraught situation, showcasing both his weakness and his determination, is dramatic because it touches upon more than the political moment and more than one man’s character.
And that’s not all. Biden has come to symbolize both the biological challenges and the existential poignancy of aging – of aging in power, certainly, but also just the unrelenting wear and tear of growing old.
The pressure of all these factors makes Biden a tragic figure.
Others reluctant to step down
To see this clamorous moment in the light of the past doesn’t make living in the present easier, but it does widen the perspective. Biden is far from the first person in a position of power who has been reluctant to step down – even when common sense or sheer weariness might dictate otherwise. In recent history, Supreme Court Justice Ruth Bader Ginsburg is often cited as an unfortunate example, and there are many other figures historians can cite.
Literature has always been concerned not only with people in power but also with the life cycle and the complexities of family relationships. Myths stay fresh and timeless; as we age, our understanding of a myth may change.

In Homer’s “Iliad,” the elderly Nestor endlessly reminisces. Although listened to respectfully, he is a figure from an earlier generation whose role in war has dwindled to that of counselor.
Priam, the old king of Troy, heartbroken after the death of his son Hector, still finds the energy to berate his surviving sons as they clumsily hitch the mules that will draw the cart loaded with ransom so Priam can redeem his dead son’s body from the warrior who killed him, Achilles.
The subsequent moment of recognition between Priam and Achilles is one of the most poignant in literature, not least because the sight of old Priam reminds Achilles of his own aged father. Achilles might be expected to be enraged, but seeing Priam turns his anger to grief. Achilles knows he won’t see his father, Peleus, again. Being old is no protection against suffering; the aged Priam, mourning his son Hector, is assailed by the same desolate grief as Achilles.
But Lear refuses to cede control. Finally, as he sinks into confusion, he discovers humility and compassion – too late. Lear is reunited in prison with his loyal daughter Cordelia, who hasn’t been afraid to speak truth to power but who also has never ceased to love him – but she is summarily executed, and Lear, heartbroken, dies.
Decision requires ‘rare detachment’
Political commentator Bill Maher has called ageism the last respectable prejudice. It’s as if age and its accompanying disabilities create a force field keeping others at a distance. Or perhaps age bestows a universally recognized vulnerability on people who seemed powerful.
Either way, old people can seem somehow separated from the rest of us.
It’s hard even to imagine President Biden alone; on the contrary, he is apparently surrounded by loyal familyand advisers. But the vulnerability of old age was on full display in the first presidential debate. News reports convey how hard it has become for anyone outside Biden’s tight circle to really see or know him.
One of the countless contrasts between Biden and Donald Trump is Biden’s almost sphinxlike unknowability, especially now. With Trump, as has frequently been noted, what you see is what you get. For better or for worse, his qualities are consistently on full display.
Age has been traditionally associated with wisdom, yet the wisdom old age can bestow seems out of reach for a figure still in the thick of politics. Lear’s “all-licensed” Fool rebukes the king: “Thou shouldst not have been old till thou had been wise.”
Only withdrawing from the fray might bestow some tranquility. But the vision to make the difficult decision to withdraw requires a kind of detachment that seems to be very rare in history, and not common in literature either.

‘Almighty time disquiets’
Greek tragedy does offer an eloquent example of just such wisdom.
Sophocles’s “Oedipus at Colonus” is a play about an old man written by an old man – Sophocles was in his 90s when the drama was presented.
The aged, self-blinded and self-exiled former king Oedipus, guided by his loyal daughter, finds himself in Colonus, a holy district outside Athens. When Theseus, the ruler of Athens, arrives on the scene, Oedipus’s words to him transcend both the immediate situation and Oedipus’s dire backstory.
“The immortal Gods alone have neither age nor death! All other things almighty Time disquiets. Earth wastes away; the body wastes away; Faith dies, distrust is born. And imperceptibly the spirit changes Between a man and his friend, or between two cities …. … but time goes on, Unmeasured Time, fathering numberless Nights, unnumbered days ….”
By touching upon the shared human condition of mortality, as well as another universal, the inevitability of change, this speech bestows a stark tranquility on the situation.
Oedipus knows that he has come to Colonus to die, and his words convey a vision that seems to issue from beyond the grave. His detachment has an authority that now seems almost out of the reach of any of us, let alone a politician. But it’s good to remember that such qualities exist.
Of course this is a different moment. The looming juggernaut that Trump represents makes it hard for Biden’s supporters, or any Democrats, to be calm. Nevertheless, it’s useful to think about the potential strengths, as well as the vulnerabilities, of age.
The widespread anxiety now rampant among Biden’s supporters is sometimes mocked as unjustified panic. Time, as Oedipus might remind us, will tell. I personally find this anxiety touching and heartening for its humanity; there’s widespread compassion for Biden’s vulnerability.
In the ugly spectacle of American politics, it’s hard to keep humanity in sight. Literature can remind us of what we already know about growing old, about change, and about mortality.
