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 […]

Gov. Ron DeSantis signs law erasing “climate change” from Florida policy – “This purposeful act of cognitive dissonance is proof that the governor and the state legislature are not acting in the best interests of Floridians, but rather to protect profits for the fossil fuel industry”

By Sheri Walsh 16 May 2024 (UPI) – With summer’s extreme heat and this year’s hurricane season rolling into Florida next month, Gov. Ron DeSantis signed legislation Wednesday that will erase climate change from state policy effective 1 July 2024. The new law will erase the words “climate change” from state statutes and make energy […]

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.

Big Oil spent decades sowing doubt about fossil fuel dangers, experts testify – “Big Oil had to evolve from denial to duplicity”

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, […]

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 […]

South Texas farmers are in peril as the Rio Grande Valley runs dry, again – “Without water, what are we using to grow our crops? What are we able to pay back those loans with?”

By Berenice Garcia 18 April 2024 MERCEDES, TEXAS (The Texas Tribune) – Across the street from a red barn, a 40-acre field once covered by a sea of green sugar cane leaves now sits dry and thirsty. Irrigation water is dangerously elusive for the fields of the Rio Grande Valley. Mike England, who owns England […]

Twenty-first century groundwater-level trends in globally distributed monitoring wells. Each point represents one monitoring well, coloured to represent the Theil–Sen trend of annual median groundwater levels during the twenty-first century. Blue and red points indicate shallowing and deepening, respectively, of groundwater levels over time, with darker colours indicating faster rates. a, Spatial distributions of groundwater-level trends in globally distributed monitoring wells. b–o, Regional maps illustrating the substantial spatial variability in groundwater-level trends. Supplementary Notes 16 and 17 show monitoring wells and their groundwater-level trends at subcontinental scales (Supplementary Note 16) and in 207 individual aquifer systems.

Groundwater resources are drying up across the globe – “Climate variability and change can impact water supplies underground as well as above-ground”

By Matthew Rozsa 24 January 2024 (Salon) – Humans rely on groundwater for many things, but especially our food. Roughly 30 percent of all the planet’s available freshwater comes from groundwater, or water that is found underground in the spaces between rocks, soil and sand. It is primarily used for agriculture and billions of humans are dependent […]

Spatial distribution of the total number of exposed days in 995 California ZIP Code Tabulation Areas (ZCTA) from 2006 to 2019 under the main analysis definition for climate hazards (85th percentile for extreme heat and 15 μg/m3 for wildfire PM2.5). (A) Compound exposure, (B) extreme heat alone, and (C) wildfire smoke alone. Gray color represents excluded ZCTA that has a population of ≤1000 or lacks any exposed day (extreme heat alone, wildfire smoke alone, or both). Graphic: Chen, et al., 2024 / Science Advances

Extreme heat, wildfire smoke harm low-income and nonwhite communities the most – “It’s really important to highlight this social injustice aspect of climate change”

By Dorany Pineda 2 February 2024 LOS ANGELES (AP) – Extreme heat and wildfire smoke are independently harmful to the human body, but together their impact on cardiovascular and respiratory systems is more dangerous and affects some communities more than others. A study published Friday in the journal Science Advances said climate change is increasing the frequency […]

A new surge in power use is threatening U.S. climate goals – “I can’t recall the last time I was so alarmed about the country’s energy trajectory”

By Brad Plumer 17 March 2024 (The New York Times) – Something unusual is happening in America. Demand for electricity, which has stayed largely flat for two decades, has begun to surge. Over the past year, electric utilities have nearly doubled their forecasts of how much additional power they’ll need by 2028 as they confront […]
