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.
