The United Nations weather agency said carbon dioxide levels in the atmosphere reached record highs last year, intensifying climate change and extreme weather.

The Paris agreement is complex and works in a slow bureaucratic manner.

A new draft of a deal on money to curb and adapt to climate change released Friday afternoon at the United Nations climate summit pledged $250 billion annually by 2035 from wealthy countries to poorer ones.

Environmental advocates released reports Friday decrying fossil fuel industry influence at these climate talks in Baku, Azerbaijan, called COP29.

For the third straight year, efforts to fight climate change haven’t lowered projections for how hot the world is likely to get.

World leaders are converging Tuesday at the United Nations annual climate conference in Azerbaijan.

After days of shaving off the edges of key warming issues, climate negotiators Tuesday are zeroing in on the tough job of dealing with the main cause of what’s overheating the planet: fossil fuels.

Fifty oil companies representing nearly half of global production are pledging to reach near-zero methane emissions and end routine flaring in their operations by 2030.

United States domestic oil production has hit an all-time high last week, contrasting with efforts to slice heat-trapping carbon emissions by the Biden administration and world leaders.

The planning and buildup of liquified and other natural gas would add 2 billion tons of carbon dioxide equivalent (1.9 billion metric tons) a year to the air by 2030, according to a report released Thursday by Climate Action Tracker at international climate talks in Egypt.

A new UN report shows that countries aren't doing enough to cut emissions of heat trapping gases.

Climate scientists say the new spending package that President Biden just signed will trim future warming a bit.

Most major countries are finding that it's easier to promise to fight climate change than to actually do it.

Almost 200 nations have accepted a compromise deal aimed at keeping a key global warming target alive, but it contained a last-minute change that watered down crucial language about coal.

A new scientific report that looks at what each nation is doing to fight climate change finds nearly every country falls short.

President Joe Biden and his team of climate experts used a virtual global summit this week to lay out Biden’s vision that fighting climate change not only can benefit the U.S. economy, but the world’s as well.
