The Trump administration’s Environmental Protection Agency Wednesday proposed a new ruling that heat-trapping carbon gas “emissions from fossil fuel-fired power plants do not contribute significantly to dangerous air pollution.

A new study finds that the broiling summer of 2023 was the hottest in the Northern Hemisphere in more than 2,000 years.

Earth’s average temperature set a new unofficial record high on Thursday, the third such milestone in a week that already rated as the hottest on record.

The world is trying to switch from electricity produced by burning fossil fuels to cleaner wind and solar power, but some people have worried that there aren't enough rare earth minerals to make the green electricity switch.

The National Academy of Sciences says the world needs to look into making oceans suck up more carbon dioxide to fight climate change.

The Biden administration and Democrats talked the climate talk at U.N. negotiations in Scotland.

Scientists say there’s something different this year as the world staggers through another summer of extreme weather.

The United States is rejoining the international Paris climate accord and is also joining many other nations in setting an ambitious goal that once seemed unattainable: net-zero carbon emissions by midcentury. That means lots of changes designed to fight increasingly costly climate disasters such as wildfires, floods, droughts, storms and heat waves. It gets rougher ahead,” said climate scientist Zeke Hausfather, climate and energy director at the Breakthrough Institute. AdHis administration promises to reveal the goal, required by the climate agreement but nonbinding, before its Earth Day climate summit, April 22. Getting to net zero carbon emissions midcentury means about a 43% cut from 2005 levels — the baseline the U.S. government uses — by 2030, said the Rhodium Group’s Larsen.

Just how warm Earth stays this December will determine if 2020 goes down as the hottest year on record. Earth’s temperature in November was 56.95 degrees (13.87 degrees Celsius), which was 1.75 degrees (0.97 degrees Celsius) above the 20th century average, according to NOAA. Florida, Virginia and Maryland so far have had their hottest year on record, while California had its hottest fall. For its part, NASA said 2020 so far is the warmest on record and it's likely to stay that way. Using NASA data, if December is just 0.59 degrees (0.33 degrees Celsius) above the 1980 to 2010 average, 2020 should be the hottest year on record.

A 2018 U.N. science report said a world hotter than that still survives, but chances of dangerous problems increase tremendously. Earlier this year, Death Valley hit 130 degrees (54.4 degrees Celsius) and Siberia hit 100 degrees (38 degrees Celsius). The probability of 1.5 degrees (Celsius) is growing year by year, Taalas told The Associated Press. California is fighting record wildfires as the report was issued. So far, this year is the second hottest on record and has a 37% chance of surpassing the global record set in 2016, according to the U.S. National Oceanic and Atmospheric Administration.
