“One of the first conditions of happiness is that the link between man and nature shall not be broken”*…
The estimable Jonathan Watts on the (painfully) pivotal year just ended…
As historically high temperatures continued to be registered in many parts of the world in late December, the former Nasa scientist James Hansen told the Guardian that 2023 would be remembered as the moment when failures became apparent.
“When our children and grandchildren look back at the history of human-made climate change, this year and next will be seen as the turning point at which the futility of governments in dealing with climate change was finally exposed,” he said.
“Not only did governments fail to stem global warming, the rate of global warming actually accelerated.”…
The bright side of this clear dichotomy is that young people may realise that they must take charge of their future. The turbulent status of today’s politics may provide opportunity,” he said.
…
His comments are a reflection of the dismay among experts at the enormous gulf between scientific warnings and political action. It has taken almost 30 years for world leaders to acknowledge that fossil fuels are to blame for the climate crisis, yet this year’s United Nations Cop28 summit in Dubai ended with a limp and vague call for a “transition away” from them, even as evidence grows that the world is already heating to dangerous levels…
Veteran climate watchers have been horrified at the pace of change. “The climate year 2023 is nothing but shocking, in terms of the strength of climate occurrences, from heatwaves, droughts, floods and fires, to rate of ice melt and temperature anomalies particularly in the ocean,” Prof Johan Rockström, the joint director of the Potsdam Institute for Climate Impact Research in Germany, said.
…
Aquino [Francisco Eliseu Aquino, a professor of climatology and oceanography at the Federal University of Rio Grande do Sul and the deputy director of Brazil’s polar and climatic centre] said human influence – through the burning of fossil fuels – had also created “frightening” dynamics between the poles and the tropics. Cold wet fronts from the Antarctic had interacted with record heat and drought in the Amazon to create unprecedented storms in between. Floods in southern Brazil killed 51 people in early September and then returned with similarly devastating force in mid-November.
Aquino said this “record record” was a taste of what was to come as the world entered dangerous levels of warming. “From this year onwards, we will understand concretely what it means to flirt with 1.5C [of heating] in the global average temperature and new records for disasters,” he said.
This is already happening. This year’s deadliest climate disaster was the flood in Libya that killed more than 11,300 people in the coastal city of Derna. In a single day, Storm Daniel unleashed 200 times as much rain as usually falls on the city in the entire month of September. Human-induced climate change made this up to 50 times more likely.
Forest fires burned a record area in Canada and Europe, and killed about 100 people in Lahaina on Maui island, the deadliest wildfire in recent US history, which happened in August. For those who prefer to calculate catastrophe in economic terms, the US broke its annual record of billion-dollar disasters by August, by which time there had already been 23.
…
…as science has proved beyond any doubt, global temperatures would continue to rise as long as humanity continues to burn fossil fuels and forests.
In the years ahead, the heat “anomaly” and catastrophes of 2023 would first become the new norm, and then be looked back on as one of the cooler, more stable years in people’s lives. As Hansen warned, unless there is radical and rapid change, failure will be built into the climate system…
Bracing, but critically important– eminently worth reading in full: “World will look back at 2023 as year humanity exposed its inability to tackle climate crisis, scientists say,” from @jonathanwatts in @guardian.

As we face facts, we might recall that it was on this date in 1870 that Congress authorized the formation of the U.S. weather service (later named the Weather Bureau; later still, the National Weather Service), and placed it under the direction of the Army Signal Corps. Cleveland Abbe, who had started the first private weather reporting and warning service (in Cincinnati) and had been issuing weather reports or bulletins since 1869, was the only person in the country at the time who was experienced in drawing weather maps from telegraphic reports and forecasting from them. He became the weather service’s inaugural chief scientist– effectively its founding head– in January, 1871. The first U.S. meteorologist, he is known as the “father of the U.S. Weather Bureau,” where he systemized observation, trained personnel, and established scientific methods. He went on to become one of the 33 founders of the National Geographic Society.
“The redwood is one of the few conifers that sprout from the stump and roots, and it declares itself willing to begin immediately to repair the damage of the lumberman and also that of the forest-burner”*…
Nature plans ahead: how redwoods survive fire…
When lightning ignited fires around California’s Big Basin Redwoods State Park north of Santa Cruz in August 2020, the blaze spread quickly. Redwoods naturally resist burning, but this time flames shot through the canopies of 100-meter-tall trees, incinerating the needles. “It was shocking,” says Drew Peltier, a tree ecophysiologist at Northern Arizona University. “It really seemed like most of the trees were going to die.”
Yet many of them lived. In a paper published [in late November] in Nature Plants, Peltier and his colleagues help explain why: The charred survivors, despite being defoliated, mobilized long-held energy reserves—sugars that had been made from sunlight decades earlier—and poured them into buds that had been lying dormant under the bark for centuries.
“This is one of those papers that challenges our previous knowledge on tree growth,” says Adrian Rocha, an ecosystem ecologist at the University of Notre Dame. “It is amazing to learn that carbon taken up decades ago can be used to sustain its growth into the future.” The findings suggest redwoods have the tools to cope with catastrophic fires driven by climate change, Rocha says. Still, it’s unclear whether the trees could withstand the regular infernos that might occur under a warmer climate regime.
…
It’s not just the energy reserves that are old. The sprouts were emerging from buds that began forming centuries ago. Redwoods and other tree species create budlike tissue that remains under the bark. Scientists can trace the paths of these buds, like a worm burrowing outward. In samples taken from a large redwood that had fallen after the fire, Peltier and colleagues found that many of the buds, some of which had sprouted, extended back as much as 1000 years. “That was really surprising for me,” Peltier says. “As far as I know, these are the oldest ones that have been documented.”
Although the redwoods have sprouted new growth, Peltier and other forest experts wonder how the trees will cope with far less energy from photosynthesis, given that it will be years before they grow as many needles as they had before the fire. “They’re alive, but I would be a little concerned for them in the future.”
Another question is how the redwoods would cope if a second catastrophic fire strikes soon. Have they used up their emergency reserves? “The fact that the reserves used are so old indicates that they took a long time to build up,” says Susan Trumbore, a radiocarbon expert at the Max Planck Institute for Biogeochemistry. “Redwoods are majestic organisms. One cannot help rooting for those resprouts to keep them alive in decades to come.”…
After a devastating conflagration, trees regrow using energy stored long ago: “Ancient redwoods recover from fire by sprouting 1000-year-old buds,” from @ScienceMagazine.

As we learn from nature, we might spare a thought for Louis Agassiz; he died on this date in 1873. A biologist and geologist, he was an important early scholar of Earth’s natural history. After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel. He emigrated to the United States in 1847 after visiting Harvard University and went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School, and to found its Museum of Comparative Zoology.
Agassiz is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages. He founded the field of glaciology.
His second wife, Elizabeth Cabot Agassiz (née Cary) collaborated with him on much of his work and went on to found Radcliffe College.

The estimable Ted Gioia suggests that we’re living in a time without a counterculture…
These are the key indicators that you might be living in a society without a counterculture:
• A sense of sameness pervades the creative world
• The dominant themes feel static and repetitive, not dynamic and impactful
• Imitation of the conventional is rewarded
• Movies, music, and other creative pursuits are increasingly evaluated on financial and corporate metrics, with all other considerations having little influence
• Alternative voices exist—in fact, they are everywhere—but are rarely heard, and their cultural impact is negligible
• Every year the same stories are retold, and this sameness is considered a plus
• Creative work is increasingly embedded in genres that feel rigid, not flexible
• Even avant-garde work often feels like a rehash of 50-60 years ago
• Etc. etc. etc.
He then illustrates his point with a series of 14 tweets: “14 Warning Signs That You Are Living in a Society Without a Counterculture,” from @tedgioia.
* “To choose the wrong strategy is a serious matter. All the movements that only play on liberation, emancipation, on the resurrection of a subject of history, of the group, of the word based on “consciousness raising,” indeed a “raising of the unconscious” of subjects and of the masses, do not see that they are going in the direction of the system, whose imperative today is precisely the overproduction and regeneration of meaning and of speech.” — Jean Baudrillard, Simulacra and Simulation

As we ferret out ferment, we might recall that it was on this date in 2008 that a worker using a blowtorch to warm up some asphalt shingles at the Universal Studios Hollywood theme park neglected to check that all of them had cooled before he left, and a three-alarm fire broke out. It destroyed three acres of the studio’s back lot tour (including “New York Street,” “New England Street,” and the attraction known as “King Kong Encounter”).
But worse, it obliterated Building 6197 and its contents– between 40,000 and 50,000 archived digital video and film copies were destroyed along with 118,000 to 175,000 audio master tapes belonging to Universal Music Group. Among the artists whose masters were destroyed were Nirvana, Elton John, R.E.M., Sonic Youth, Beck, Bryan Adams, Sheryl Crow, Jimmy Eat World, Suzanne Vega, Les Paul, The Surfaris, and Bryan Adams.
“Everything we know and love about the universe and all the laws of physics as they apply, apply to four percent of the universe”*…
In 1969, the American astronomer Vera Rubin puzzled over her observations of the sprawling Andromeda Galaxy, the Milky Way’s biggest neighbour. As she mapped out the rotating spiral arms of stars through spectra carefully measured at the Kitt Peak National Observatory and the Lowell Observatory, both in Arizona, she noticed something strange: the stars in the galaxy’s outskirts seemed to be orbiting far too fast. So fast that she’d expect them to escape Andromeda and fling out into the heavens beyond. Yet the whirling stars stayed in place.
Rubin’s research, which she expanded to dozens of other spiral galaxies, led to a dramatic dilemma: either there was much more matter out there, dark and hidden from sight but holding the galaxies together with its gravitational pull, or gravity somehow works very differently on the vast scale of a galaxy than scientists previously thought.
Her influential discovery never earned Rubin a Nobel Prize, but scientists began looking for signs of dark matter everywhere, around stars and gas clouds and among the largest structures in the galaxies in the Universe. By the 1970s, the astrophysicist Simon White at the University of Cambridge argued that he could explain the conglomerations of galaxies with a model in which most of the Universe’s matter is dark, far outnumbering all the atoms in all the stars in the sky. In the following decade, White and others built on that research by simulating the dynamics of hypothetical dark matter particles on the not-so-userfriendly computers of the day.
But despite those advances, over the past half century, no one has ever directly detected a single particle of dark matter. Over and over again, dark matter has resisted being pinned down, like a fleeting shadow in the woods. Every time physicists have searched for dark matter particles with powerful and sensitive experiments in abandoned mines and in Antarctica, and whenever they’ve tried to produce them in particle accelerators, they’ve come back empty-handed. For a while, physicists hoped to find a theoretical type of matter called weakly interacting massive particles (WIMPs), but searches for them have repeatedly turned up nothing…
Dark matter is the most ubiquitous thing physicists have never found. Is it time to consider alternative explanations? “Does dark matter exist?“

As we interrogate the invisible, we might recall that it was on this date in 1944 that one of the worst fire disasters in U.S. history occurred; the blaze broke out during an afternoon performance of the Ringling Bros. and Barnum & Bailey Circus that was attended by an estimated 7,000 people. It killed 167 people; more than 700 were injured.

“Oxygen / Everything needs it”*…
As tongues of flame lapped the planet’s largest tract of rain forest over the past few weeks, it has rightfully inspired the world’s horror. The entire Amazon could be nearing the edge of a desiccating feedback loop, one that could end in catastrophic collapse. This collapse would threaten millions of species, from every branch of the tree of life, each of them—its idiosyncratic splendor, its subjective animal perception of the world—irretrievable once it’s gone. This arson has been tacitly encouraged by a Brazilian administration that is determined to develop the rain forest, over the objections of its indigenous inhabitants and the world at large. Losing the Amazon, beyond representing a planetary historic tragedy beyond measure, would also make meeting the ambitious climate goals of the Paris Agreement all but impossible. World leaders need to marshal all their political and diplomatic might to save it.
The Amazon is a vast, ineffable, vital, living wonder. It does not, however, supply the planet with 20 percent of its oxygen.
As the biochemist Nick Lane wrote in his 2003 book Oxygen, “Even the most foolhardy destruction of world forests could hardly dint our oxygen supply, though in other respects such short-sighted idiocy is an unspeakable tragedy.”…
There are very many very good reasons not to burn down the Amazon rain forest. Still, humans could burn every living thing on the planet and still not dent its oxygen supply: “The Amazon Is Not Earth’s Lungs.”
(Again– burning down the rainforest is bad, very very bad. But as long-time environmental reporter Michael Shellenberger argues, if we ground our concerns in the actual details of what’s happening, we’re much likelier to find effective responses.)

As we take a deep breath, we might recall that it was on this date in 1666 that the Great Fire of London broke out. The conflagration raged for four days, mostly in the City of London, within the old Roman walls; it did not spread to the aristocratic district of Westminster, to Charles II’s Palace of Whitehall, nor to most of the suburban slums. It destroyed 13,200 houses, St. Paul’s Cathedral, and 87 parish churches. Miraculously, fewer than 20 people lost their lives.
