Tree cover globally cools nearly half of the warming from built-up cities, but it’s doing it more in richer, cooler areas and less in hotter poorer areas where it’s needed most.

Researchers say the United States emitted 2.4% more greenhouse gases in 2025 than the previous year.

Republican lawmakers are blaming Canada for not preventing and containing wildfires, whose smoke has fouled the air in several states this year.

The Trump administration wants to end two NASA missions that monitor a potent greenhouse gas and plant health.

The United Nations reports a global shift toward renewable energy, calling it a "positive tipping point."

A team of 60 international scientists report that by early 2028 society will have emitted enough greenhouse gases that the Earth will be pretty much locked into hitting the internationally agreed upon preferred limit for global warming.

Around the globe, hotter temperatures stoked by climate change are increasing the odds of both severe drought and heavier precipitation that can wreak havoc on people and the environment.

The European climate service Copernicus says the world warmed to yet another monthly heat record in January, despite an abnormally chilly United States, a cooling La Nina and predictions of a slightly less hot year.

The U.N. weather agency is sounding a “red alert” about global warming, citing record-smashing increases last year in greenhouse gases, land and water temperatures and melting of glaciers and sea ice.

The record-breaking heat that has pushed California's electrical grid to the breaking point for more than a week is almost over but it's a sign of things to come.

Experts say the winter grassland fire that blew up along Colorado’s front range was rare.

While world leaders hail the Glasgow climate pact as a good compromise that keeps a key temperature limit alive, scientists are much more skeptical.

Freak natural disasters most with what scientists say likely have some kind of climate change connection seem to be everywhere in the crazy year 2020. But experts say well probably look back and say those were the good old days, when disasters werent so wild. Its going to get A LOT worse, Georgia Tech climate scientist Kim Cobb said Wednesday. Thats because what's happening now is just the type of crazy climate scientists anticipated 10 or 20 years ago. Just as the future of climate disasters is hard to fathom now.
