Cutting greenhouse gas emissions rapidly and immediately will save lives, livelihoods and ecosystems around the world, scientists say. And there are lots of ways to go about it.

A report from the United Nations is expected to lay out options to help world leaders curb emissions, and protect people from the effects of climate change.

A new study suggests that climate change is making back-to-back hurricanes more typical, which could make it tougher for coastal communities to recover.

Climate change is making flooding and wind damage from hurricanes more common in the U.S. That means dangerous storms are getting more frequent, even though the total number of storms isn't changing.

There is one number that the Environmental Protection Agency relies on to decide which climate policies to pursue. So why does that number assume the lives of richer people are worth more?

The EPA is updating its most powerful climate policy tool: a single number called the social cost of carbon. The new number is more accurate, but is also raising ethical concerns.

Oil refineries release billions of pounds of pollution into waterways each year, according to regulatory data. NPR found that pollution is concentrated near places where people of color live.

The connection between weather and climate change has never been clearer. And simultaneous extremes, such as hot and dry weather together, are particularly dangerous.

The Environmental Protection Agency announced new limits on dangerous soot pollution. Public health officials say reducing soot in the air saves lives.

A new study suggests that mid-latitude glaciers, including those in western Canada, the Rocky Mountains and central Europe, will be gone by the end of the century.

Climate goals can feel distant. But climate change is happening right now. Speed up the benefits for taking action, psychologists say, if you want leaders and others to pay attention and act.

This year's hurricane season got off to a very slow start. But it only takes one big storm to wreak havoc. And climate change makes such storms more likely.

Scientists and forecasters are trying to figure out how to talk about the connection between climate change and severe weather. It could have big impacts on how people think about global warming.

Delegates reached a last-minute deal to pay vulnerable countries for damages caused by climate change. But the final agreement does not put humanity on track to avoid catastrophic warming.

Despite new agreements to limit methane emissions and beef up weather forecasts, vulnerable countries aren't getting any more help and the Earth is headed for catastrophic warming.

Climate change is an everyday reality for students and teachers living in the Himalayan mountains of Nepal. At one school, they are trying to learn more about the forces that could upend their lives.

President Biden touted American progress reining in emissions and said he intends to push for more money for developing countries. Here's what happened at COP27 today.

The President said the United States is cutting its greenhouse gas emissions, and promised again to give more money to developing countries on the front lines of climate change.

Russia's war in Ukraine also threatens to wreck climate goals, members of Congress arrive, and an actor changes his name to draw attention to global warming

Global leaders are negotiating about how to cut greenhouse gas emissions as quickly as possible. Scientists say every passing day, and every tenth of a degree, makes a big difference.
