Some experts tee up public comment on EPA report calling fossil fuel concerns overblown, as others fast-track review
The report, which is being used to justify the rollback of a huge number of climate regulations, is full of misinformation—with many claims based on long-debunked research.

blue whale vocalizations dropped by almost 40 percent, according to the study, with populations of krill and anchovy collapsing. "When you really break it down, it’s like trying to sing while you're starving," Ryan explained. "They were spending all their time just trying to find food."
Heat caused 2,300 deaths across 12 cities, of which 1,500 were down to climate crisis, scientists say
The human fingerprint on global warming was likely evident in Earth’s atmosphere far earlier than previously thought—even before the invention of modern cars, a new study says. Using a combination of scientific theory, modern observations and multiple, sophisticated computer models, researchers found a clear signal of human-caused climate change was likely discernible with high confidence as early as 1885, just before the advent of gas-powered cars but after the dawn of the industrial revolution.
Breaching threshold would ramp up catastrophic weather events, further increasing human suffering
Major study finds world's most productive farming regions are especially vulnerable to rising temperatures, and face steep declines in agricultural output this century.
There’s frustration among researchers that falling pH levels in seas around the globe are not being taken seriously enough, and that until the buildup of CO2 is addressed, the consequences for marine life will be devastating
Societies increasingly rely on scientists to guide decisions in times of uncertainty, from pandemic outbreaks to the rise of artificial intelligence. Addressing climate change is no different. For governments wanting to introduce ambitious climate policies, public trust in climate scientists is pivotal, because it can determine whether voters support or resist those efforts.
Methane emissions spiked starting in 2020. Scientists say they have found the culprit.
