Responses of 380 climate experts to the question, “How high above pre-industrial levels do you think average global temperature will rise between now and 2100? Almost 80 percent of the respondents, all from the authoritative Intergovernmental Panel on Climate Change (IPCC), foresee at least 2.5°C of global heating, while almost half anticipate at least 3°C (5.4°F). Only 6 percent thought the internationally agreed 1.5°C (2.7°F) limit would be met. Graphic: The Guardian

World’s top climate scientists expect global heating to blast past 1.5C target – “I could not feel greater despair over the future”

By Damian Carrington 8 May 2024 (The Guardian) – Hundreds of the world’s leading climate scientists expect global temperatures to rise to at least 2.5C (4.5F) above preindustrial levels this century, blasting past internationally agreed targets and causing catastrophic consequences for humanity and the planet, an exclusive Guardian survey has revealed. Almost 80% of the […]

From flooding in Brazil and Houston to brutal heat in Asia, extreme weather seems nearly everywhere in 2024 – “We’re departing the climate of the 20th century right now and we just can’t handle these events”

By Seth Borenstein, Suman Naishadham, Sibi Arasu, and Fabiano Maisonnave 7 May 2024 (AP News) – In sweltering Brazil, flooding killed dozens of people and paralyzed a city of about 4 million people. Voters and politicians in India, amid national elections, are fainting in heat that hit as high as 115 degrees (46.3 degrees Celsius). […]

DDT found in deep-sea fish raises troubling concerns for food web – “Nothing is untouched”

By Rosanna Xia 6 May 2024 (Los Angeles Times) – For several years now, one question has held the key to understanding just how much we should worry about the hundreds of tons of DDT that had been dumped off the coast of Los Angeles: How, exactly, has this decades-old pesticide — a toxic chemical spread across […]

Global measles cases nearly doubled in one year, researchers say – “A crisis among many crises”

By Katherine Dillinger 27 April 2024 (CNN) – The number of measles cases around the world nearly doubled from 2022 to 2023, researchers say, presenting a challenge to efforts to achieve and maintain elimination status in many countries. There were 171,153 cases globally in 2022, according to Dr. Patrick O’Connor of the World Health Organization, […]

Shell plant reported millions of “phantom” carbon credits – “Selling emissions credits for reductions that never happened literally makes climate change worse”

By Kenza Bryan and Clara Murray 4 May 2024 LONDON (Financial Times) – A Shell-operated plant reported millions of carbon credits tied to CO₂ removal that never took place but were used by Canada’s largest oil sands companies, raising new doubts about a technology seen as crucial to mitigating greenhouse gas emissions. As part of […]

Graph showing reconstructed and observed annual temperature data for the Northern Hemisphere’s summer months (June, July, and August) at 30 and 90 degrees north latitude. Anomalies indicate how the average temperature of each year’s summer compared with the average reconstructed temperature from the baseline period of 1850-1900. The summer of 2023 was clearly the hottest in the past 2,000 years, with a temperature that proved to be at least 0.5 degree C above that of C.E.246—a time that was the hottest summer before direct measurements began and long before human-caused warming emerged.

2023 was the hottest summer in two thousand years – “When you look at the long sweep of history, you can see just how dramatic recent global warming is”

By Sarah Collins 14 May 2024 (University of Cambridge) – Researchers have found that 2023 was the hottest summer in the Northern Hemisphere in the past two thousand years, almost four degrees warmer than the coldest summer during the same period. Although 2023 has been reported as the hottest year on record, the instrumental evidence […]

Effect of political contributions from oil and gas companies on U.S. legislators that vote against the environment. Coefficients and 95 percent CIs for tests of investment (Left) and influence (Right) hypotheses and their corresponding metaanalytic effects for the years 1992 to 2018. In 13 out of 14 analyses, lower LCV scores (i.e., more antienvironmental votes) in one election cycle predicted significantly increased contributions in the following election cycle. For example, the strongest result was observed for the 2016 election: For every additional 10 percent of congressional votes against the environment in 2014, a legislator would receive an additional $5,400 in campaign contributions from oil and gas companies in 2016 (b = −0.54, SE = 0.12; P < 0.001; 95 percent CI [−0.77, −0.31]). This is an especially strong relationship considering that many elected officials vote against environmental policies nearly 100 percent of the time, thereby compounding the cycle of antienvironmentalism and increasing rewards in the form of contributions.

By Dharna Noor 1 May 2024 (The Guardian) – The fossil fuel industry spent decades sowing doubt about the dangers of burning oil and gas, experts and Democratic lawmakers testified on Capitol Hill on Wednesday. The Senate budget committee held a hearing to review a report published on Tuesday with the House oversight and accountability […]

Map showing worldwide natural disasters in 2023. Worldwide, natural disasters in 2023 resulted in losses of around US$250 billion (previous year US$250 billion). Loss statistics were characterised by the large number of severe regional storms. Such high thunderstorm losses have never been recorded before in the USA or in Europe: assets worth around US$66 billion were destroyed in North America, of which US$50 billion was insured, while in Europe the figure was US$10 billion (€9.1 billion), of which US$8 billion (€7.3 billion) was insured. A large body of scientific research indicates that climate change favours severe weather with heavy hailstorms. Similarly, loss statistics from thunderstorms in North America and other regions are trending upward. Graphic: Munich Re

Munich Re: Record thunderstorm losses in 2023 – “The warming of the earth that has been accelerating for some years is intensifying the extreme weather in many regions, leading to increasing loss potentials”

9 January 2024 (Munich Re) – Worldwide, natural disasters in 2023 resulted in losses of around US$ 250bn (previous year US$ 250bn), with insured losses of US$ 95bn (previous year US$ 125bn). Overall losses tally with the five-year average, while insured losses were slightly below the average figure of US$ 105bn. Unlike in previous years, […]

Hectares of primary forest lost each year in Indonesia, 2001-2023. For a second year, Indonesia saw an uptick in forest losses. Between 2002 and 2023, the country lost 11 percent of its primary forest — that is, mature natural forests that have not been touched in recent years. Data: Global Forest Watch. Graphic: M.K.

Steelhead trout, once thriving in Southern California, are declared endangered – “The negative trend toward extinction has not reversed”

By Ian James 23 April 2024 (Los Angeles Times) – Southern California’s rivers and creeks once teemed with large, silvery fish that arrived from the ocean and swam upstream to spawn. But today, these fish are seldom seen. Southern California steelhead trout have been pushed to the brink of extinction as their river habitats have […]
