Why melting ice sheets and glaciers are affecting people thousands of miles away
Monday, April 17, 2023
The world's massive ice sheets and glaciers are melting as climate change raises temperatures. Scientists warn that disappearing ice is having surprising and far-reaching effects.
The message from a U.N. climate report is dire: Humans must cut pollution quickly
Monday, March 20, 2023
Scientists working for the United Nations released their final report on the state of the Earth's climate, current greenhouse gas emissions and the options humans have for curbing those emissions.
Cut emissions quickly to save lives, scientists warn in a new U.N. report
Monday, March 20, 2023
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.
The United Nations is expected to issue a major new climate change report

Sequential hurricanes are becoming more common because of climate changes
Wednesday, March 01, 2023
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.
Why hurricanes feel like they're getting more frequent
Monday, February 27, 2023
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.
Why the EPA puts a higher value on rich lives lost to climate change
Wednesday, February 08, 2023
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 important tool for cracking down on carbon emissions
Saturday, February 04, 2023
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 lots of water pollution near communities of color, data show
Thursday, January 26, 2023
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.
Climate change makes heat waves, storms and droughts worse, climate report confirms
Monday, January 09, 2023
The connection between weather and climate change has never been clearer. And simultaneous extremes, such as hot and dry weather together, are particularly dangerous.
How the EPA is cracking down with tighter limits on soot
Friday, January 06, 2023

How our perception of time shapes our approach to climate change
Wednesday, January 04, 2023
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.
The 2022 hurricane season shows why climate change is so dangerous
Wednesday, December 28, 2022
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.
Climate change is making the weather more severe. Why don't most forecasts mention it?
Wednesday, November 23, 2022
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.
Did the world make progress on climate change? Here's what was decided at global talks
Sunday, November 20, 2022
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.
Climate talks are wrapping up. The thorniest questions are still unresolved.
Thursday, November 17, 2022
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.
