It took about 30 teams of scientists worldwide, using supercomputers to churn through mountains of data, to see patterns aligning of what will happen decades and centuries from now.
The 1997 Kyoto treaty set targets for cutting greenhouse gas emissions that many nations didn't meet. This time, stakes are higher and all countries will be asked to set and meet their own limits.
Producers and consumers in southwestern Alaska see one upside to climate change. It's now possible to farm in parts of the tundra where agriculture was unheard of just a few years ago.
In the last decade, the Gulf of Maine warmed faster than 99.9 percent of the global ocean. The rapid warming explains why recent fishing policies failed to rebuild the cod population, a study finds.
Hurricane Patricia's record-breaking winds come as a powerful El Niño heats the Pacific Ocean. But researchers say that's not enough to blame climate change for the storm's rapid strengthening.
Bull trout are dwindling in Montana as their home waters warm and invasive fish devour them. Scooping up threatened fish and moving them higher up the mountain could backfire. Is the risk worth it?
The majority of Americans favor government action, but the candidates — and big donors — differ greatly. Here is what they've said on the topic, beginning with whether climate change is real.
The international report card is out and confirms the hottest average on record — for a third time in 15 years. More than 400 scientists contributed data, finding a spike in sea and air temperatures.
On Thursday, the Vatican releases Pope Francis' document on the environment and poverty. He has said he believes global warming is a moral, and man-made, issue — angering climate change skeptics.
The littlest things — punctuation, precise word choice and grammar — can hold tremendous power in worldwide climate negotiations. This year in Europe, editors get a chance to help make history.
It's a nightmarish job: No exercise or fresh air and little food and sleep for days at a time, all in an effort to persuade 200 countries to save Earth's climate and the planet. Can they do it?
It's all in the timing. Biologists haven't been able to breed embryos of the rare, pillar coral in the lab because it's been tough to catch the creatures in the act.
The U.S. Navy has completed the largest robotic survey of the Arctic ever attempted. Warming waters are absorbing more sunlight and melting more ice there each summer, the gizmos and gliders suggest.
