The actions in Berlin, Brussels, Rio de Janeiro, New Delhi and many other cities were being organized by the youth-led group Fridays for Future, and included the group's New York chapter, which planned a march across the Brooklyn Bridge followed by a rally that organizers hoped would attract at least 1,000 people. More protests were planned Saturday and Sunday.

The amount and proportion of the powerful heat-trapping gas methane that humans spew into the atmosphere is rising, helping to turbocharge climate change, a new study finds.

Summer 2024 sweltered to Earth's hottest on record, making it even more likely that this year will end up as the warmest humanity has measured, European climate service Copernicus reported on Friday.

Moves toward phasing out fossil fuel use and gas-powered engines, for example, haven't worked by themselves, but they are more successful when combined with some kind of energy tax or additional cost system, study authors concluded in an exhaustive analysis of global emissions, climate policies and laws.

Nearly half a million people a year die worldwide from heat related deaths, far more than other weather extremes such as hurricanes, and this is likely an underestimate, a new report by 10 U.N. agencies said.

The European climate service Copernicus calculated that Tuesday’s global average temperature was 0.01 Celsius (0.01 Fahrenheit) lower than Monday's all-time high of 17.16 degrees Celsius (62.8 degrees Fahrenheit), which was .06 degrees Celsius hotter (0.1 degrees Fahrenheit) than Sunday.

Catastrophic Canadian warming-fueled wildfires last year pumped more heat-trapping carbon dioxide into the air than India did by burning fossil fuels, setting ablaze an area of forest larger than West Virginia, new research found.

Having a safe climate is becoming more of a human right globally with this week's European court decision that says countries must better protect people from climate change, something warming-hit residents of the Global South long knew, said former Ireland President Mary Robinson.

Climate change is making giant heat waves crawl slower across the globe and they are baking more people for a longer time with higher temperatures over larger areas, a new study finds.

For the ninth straight month, Earth has obliterated global heat records — with February, the winter as a whole and the world's oceans setting new high-temperature marks, according to the European Union climate agency Copernicus.
