Republican Kentucky Attorney General Russell Coleman and GOP attorneys general from 25 other states are supporting a Trump administration move to rescind a finding that underpins the federal government’s ability to regulate greenhouse gas emissions driving climate change.

We often hear about the warming risks of carbon dioxide in the atmosphere. But that’s not the only greenhouse gas we need to worry about after this

The cause of global warming shows no sign of slowing down: Levels of the three most significant human-caused greenhouse gases – carbon dioxide (CO2), methane and nitrous oxide – continued their steady climb last year, federal scientists reported this ...

Achieving net-zero greenhouse gas emissions by 2050 will require removing carbon dioxide from the atmosphere, according to the Intergovernmental Panel on Climate Change, the world’s foremost authority on the topic.

Climate scientists have made one thing clear: Staving off the worst impacts of global temperature rise requires widespread and immediate action to minimize greenhouse gas emissions. Even still, a new report shows that the most significant of those gases ...

U.S. EPA proposes removing 2009 climate pollution rules while scientists say evidence of greenhouse gas harm to health is stronger than ever.

New York Attorney General Letitia James and the state's Democratic congressional delegation are urging the EPA to maintain the 2009 "endangerment finding" establishing greenhouse gas emissions as a threat to public health and welfare,

Our atmosphere is made up of a mix of gases that sustain life by absorbing some solar radiation to heat the planet, allow livings things to breathe, and by transporting water. Nitrogen (78%) and oxygen (21%) make up the bulk of the atmosphere with trace ...

The steady drumbeat of emissions fueling global warming continued unabated in 2022, federal scientists announced this week. Levels of carbon dioxide and methane, the two greenhouse gases emitted by human activity that are the most significant ...

While methane is roughly 200 times less abundant than carbon dioxide in the atmosphere, it’s also capable of trapping more than 80 times as much heat.
