“Leaves of Three, Leave Them Be”*…
Gabrielle Emanuel on the one of climate change’s winners– the hiker’s scourge, poison ivy…
Over a decade ago, when Peter Barron started removing poison ivy for a living, he decided to document his work.
“Every year I always take pictures of the poison ivy as it’s blooming,” said Barron, who is better known as Pesky Pete, of Pesky Pete’s Poison Ivy Removal.
He still remembers the photos he took of the very first tiny, red, shiny poison ivy leaves popping out in Massachusetts and southern New Hampshire.“
When I first started, it was May 10 or May 11,” he remembered. “I was so excited. I was like, ‘Wow, the season is here’.”
Now, if he lines up all his photos from 14 years, the first sighting comes almost a month earlier. In 2023, his first glimpse was on April 18.
Barron may have unwittingly documented an effect of climate change.
Poison ivy is poised to be one of the big winners in this global, human-caused phenomenon. Scientists expect the dreaded three-leafed vine will take full advantage of warmer temperatures and rising levels of carbon dioxide in the atmosphere to grow faster and bigger — and become even more toxic.
Experts who have studied this plant for decades warn there are likely to be implications for human health. They say hikers, gardeners, landscapers and others may want to take extra precautions — and get better at identifying this plant — to avoid an itchy, blistering rash…

As we cache cortisone cream, we might send carefully-calibrated birthday greetings to Guillaume Amontons; he was born on this date in 1663. A physicist and scientific instrument inventor, he developed the air thermometer – which relies on increase in volume of a gas (rather than a liquid) to measure temperature – and used it (in 1702) to measure change in temperature in terms of a proportional change in pressure. This observation led to the concept of absolute zero in the19th century.
Deaf from childhood, Amontons worked on inventions for the hearing impaired, among them the first telegraph, which relied on a telescope, light, and several stations to transmit information over large distances. And Amontons’ laws of friction, relied upon by engineers for 300 years, state that the frictional force on a body sliding over a surface is proportional to the load that presses them together and is independent of the areas of the surfaces.

A new database shows 1,500 US lobbyists working for fossil-fuel firms while representing green groups and other with similarly contradictory concerns…
More than 1,500 lobbyists in the US are working on behalf of fossil-fuel companies while at the same time representing hundreds of liberal-run cities, universities, technology companies and environmental groups that say they are tackling the climate crisis, the Guardian can reveal.
Lobbyists for oil, gas and coal interests are also employed by a vast sweep of institutions, ranging from the city governments of Los Angeles, Chicago and Philadelphia; tech giants such as Apple and Google; more than 150 universities; some of the country’s leading environmental groups – and even ski resorts seeing their snow melted by global heating.
The breadth of fossil fuel lobbyists’ work for other clients is captured in a new database of their lobbying interests which was published online on Wednesday.
It shows the reach of state-level fossil fuel lobbyists into almost every aspect of American life, spanning local governments, large corporations, cultural institutions such as museums and film festivals, and advocacy groups, grouping together clients with starkly contradictory aims…

As we contemplate conflicts (and note that last Monday’s, then Tuesday’s “hottest day ever” records are sure to continue to be broken), we might spare a thought for Jacob Bjerknes; he died on this date in 1975. Son of Vilhelm Bjerknes, one of the pioneers of modern weather forecasting, Jacob is remembered for his seminal paper on the dynamics of the polar front, the mechanism for north-south heat transport, and for his contributions to the understanding of the weather phenomenon El Niño.

The impact of climate change on agriculture is much discussed– but mostly at the level of yields. Carolyn Beans looks into what a warming planet means for fertilization and reproduction…
… heat is a pollen killer. Even with adequate water, heat can damage pollen and prevent fertilization in canola and many other crops, including corn, peanuts, and rice.
For this reason, many growers aim for crops to bloom before the temperature rises. But as climate change increases the number of days over 90 degrees in regions across the globe, and multi-day stretches of extreme heat become more common, getting that timing right could become challenging, if not impossible.
Faced with a warmer future, researchers are searching for ways to help pollen beat the heat. They’re uncovering genes that could lead to more heat-tolerant varieties and breeding cultivars that can survive winter and flower before heat strikes. They’re probing pollen’s precise limits and even harvesting pollen at large scales to spray directly onto crops when weather improves.
At stake is much of our diet. Every seed, grain, and fruit that we eat is a direct product of pollination…
Farmers and scientists are increasingly observing that unusually high springtime temperatures can kill pollen and interfere with the fertilization of crops. Researchers are now searching for ways to help pollen beat the heat, including developing more heat-tolerant varieties: “Pollen and Heat: A Looming Challenge for Global Agriculture,” from @carolynmbeans in @YaleE360.

As we try to stay cool, we might recall that it was on this date in 1960 that chlorophyll– the green pigment responsible for photosynthesis in plants– was first synthesized. The feat was accomplished by Robert Burns Woodward, the preeminent synthetic organic chemist of the twentieth century, who was awarded the Nobel Prize in 1965 for this and other syntheses of complex natural compounds (including Vitamin b12).

The cliché, avidly promoted by Moscow, is that Russia, one of the world’s largest petro-states, will be a relative winner in climate change; but a new book argues that the country will find itself in deep trouble. Sophie Pinkham unpacks the lesson’s in Thane Gustafson’s Klimat: Russia in the Age of Climate Change…
Thane Gustafson, a longtime specialist on Russian energy, wrote Klimat: Russia in the Age of Climate Change before the [Ukraine] invasion, when the Covid pandemic seemed the great unexpected event complicating every prediction. Yet with its focus on the future of Russia’s energy, grain, and metals markets, all of which have been reconfigured by the war and the new sanctions, Klimat could hardly be more timely. Gustafson argues that Russia’s days of hydrocarbon-funded might are numbered. Unfortunately, the end of this era will not come soon enough for Ukrainians, or for the planet.
Russia is warming 2.5 times as fast as the world on average, and the Arctic is warming even faster. The cliché, avidly promoted by Moscow, is that the country will be a relative winner in climate change, benefiting from a melting and accessible Arctic shipping route, longer growing seasons, and the expansion of farmland into newly thawed areas. Gustafson counters, with a dry but persuasive marshaling of facts, that in the redistribution of wealth and power that will result from climate change, Russia is doomed. After reading Klimat, Russia’s attack on Ukraine begins to look like the convulsion of a dying state.
About two thirds of Russia is covered in permafrost, a mixture of sand and ice that, until recently, remained frozen year-round. As permafrost melts, walls built on it fracture, buildings sink, railways warp, roads buckle, and pipelines break. Anthrax from long-frozen reindeer corpses has thawed and infected modern herds. Sinkholes have opened in the melting ground, swallowing up whole buildings. Ice roads over frozen water, once the only way to travel in some remote regions, are available for ever-shorter periods. The Arctic coast is eroding rapidly, imperiling structures built close to the water…
Russia’s forests are the largest in the world, accounting for a fifth of Earth’s trees, but they are being grievously damaged by fire, drought, and disease, all of which are caused or exacerbated by climate change. Smoke has choked Siberian cities. During the 2019 fires that burned about 10,000 square miles of forest in Siberia, the Internet lit up with protest, and Russian singers and actors took part in a flash mob called “Siberia Is Burning.” President Putin sent in military units to help extinguish the fire, but he was soon rescued by rain. The problem was forgotten. As burning, dying, clear-cut forests become carbon producers rather than carbon sinks, they make the problem of climate change even worse. The same is true of melting permafrost, which releases methane, another potent greenhouse gas…
Imperialism originates in a struggle for resources; the ideology justifying the brutality of conquest and control is secondary. Oil has been one of the most coveted resources of the modern era, but the oldest and most essential resource is food. Ukraine’s famously fertile “black earth,” desired by many invaders and colonizers over the course of the country’s history, may also be among the motivations for Russia’s new aggression. According to recent reports, Russia has been commandeering or destroying Ukrainian grain stores and making off with Ukrainian agricultural equipment, smuggling the stolen grain to Syria for sale in the Middle East. Gustafson points out that as shortages become more frequent, food will become an increasingly significant tool of geopolitical influence…

As we get serious, we might send imperial birthday greetings to the man Vladimir Putin seems to wish he was: Pyotr Alekséyevich, also known as Peter I, and best known as Peter the Great; he was born on this date in 1672. But even as Putin is trying to turn back the cultural clock, Peter was the Tsar who modernized Russia and grew it into an empire, capturing ports at Azov and the Baltic Sea, laying the groundwork for the Imperial Russian Navy, ending uncontested Swedish supremacy in the Baltic, and beginning the Tsardom’s expansion into a much larger empire that became a major European power.
Peter led a cultural revolution that replaced some of the traditionalist and medieval social and political systems with ones that were modern, scientific, Westernised, and based on the Enlightenment. His reforms had a lasting impact on Russia, and many institutions of the Russian government trace their origins to his reign. He adopted the title of Emperor in place of the old title of Tsar in 1721, and founded and developed the city of Saint Petersburg, which remained the capital of Russia until 1917.

As insurance premiums rise, global warming’s effects are impacting collectors’ bank accounts, especially in disaster-prone states like California and Florida where risky conditions have become the norm…
Art collectors in California, Florida and other states experiencing weather-related disasters aggravated by climate change are finding fine art insurance becoming more expensive, with policies increasingly difficult to obtain (or renew) and containing new restrictions.
Earthquake-prone California, which has faced a series of massive wildfires (often followed by landslides) in recent years, is one epicentre in this struggle to find insurance coverage for homes and the art within them, with the annual cost of homeowners policies rising as much as 40% and the premiums for fine art insurance coverage increasing between 5% and 12%, according to Amee Yunn, assistant vice president of the New York-based Berkley Asset Protection, an insurance company specialising in fine art, jewellery and other high-value, personal and commercial assets. Florida, with its increasingly intense hurricanes and floods, is also a concern for the insurance industry.
“Many wealthy people flocked to Florida due to the pandemic,” Yunn says, “and they took their art with them.” That concentration of wealth assets in areas prone to flooding and hurricane damage creates significant risks to the financial wellbeing of insurance carriers. “We are seeing far more billion-dollar claims now than just 10 years ago,” Yunn says, causing companies like hers to write fewer new policies, increase their prices and add deductibles and exclusions. “The problem is acute.”
…
These days, insurance carriers track the advance of climate change as much as environmental scientists. “We have a corporate catastrophe team, which tracks the company’s total catastrophe exposure,” Yunn says. The risks from tornadoes in the Great Plains, hurricanes up and down the East Coast and earthquakes on the West Coast are well known, but the increasing intensity of hurricanes and tornadoes, as well as the rising numbers of them, are alarming signals. The tornado that ripped through Kentucky and several other states last year in a 200-mile path during the unlikely month of December was yet another sign of a climate that is becoming less predictable, as were a series of hurricanes, wildfires and freezing temperatures that have struck in Texas since 2017. In February 2021 a combination of snow, sleet and freezing rain paralysed Texas’s power grid for weeks, causing more than 200 deaths and nearly $200bn in damage.
“It would seem that there is nowhere safe from the effects of climate change,” [senior managing director at Risk Strategies Steve] Pincus says, all of which impacts the fine art insurance world, leading to higher prices and less available coverage…
“‘The only way to stop the bleeding is to stop writing policies’: climate change is making it more expensive to insure art,” from @TheArtNewspaper.
Via @WaltHickey, in his invaluable Numlock News, who observes “Listen, if ‘boo hoo, it’s getting too expensive to insure my vast art collection’ is the thing that gets rich people to actually care about climate change I’m still gonna take that as a win.”

As we ponder protection, we might recall that it was in this date in 1885 that the first issue of Good Housekeeping was published. A “woman’s magazine” (featuring articles on women’s interests, recipes, diet, and health), it is also known for its product testing service and its the “Good Housekeeping Seal”, a limited warranty program that is popularly known as the “Good Housekeeping Seal of Approval.” One of the oldest continuously-published magazines in the U.S., it remains popular in its category.
