sea ice

Antarctica has a lot less sea ice than usual. That’s bad news for all of us.

This year there is a lot less Antarctic sea ice, a factor in predicting global sea level rise, than ever recorded before.

El Niño has officially begun. Here’s what that means for the U.S.

The natural climate phenomenon is marked by warmer ocean temperatures in the equatorial Pacific, which drives hotter weather around the world.

Cut emissions quickly to save lives, scientists warn in a new U.N. report

World leaders already have many options to reduce greenhouse gas pollution and protect people, according to the United Nations report.

Climate change is making the weather more severe. Why don’t most forecasts mention it?

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.

Climate change makes storms like Ian more common

Storms like Hurricane Ian, which was just shy of a Category 5 hurricane when it barreled into Florida, are more likely because of human-caused climate change.

The Arctic is heating up nearly four times faster than the whole planet, study finds

The Arctic is very sensitive to climate change. In the last 40 years, the region has warmed much more rapidly than the Earth as a whole, a new study finds.

Researchers can now explain how climate change is affecting your weather

For decades, it was impossible to say that a specific weather event was caused, or even made worse, by climate change. But advanced research methods are changing that.

Climate change is killing people, but there’s still time to reverse the damage

Some ecosystems have already been irreversibly altered, scientists say. And climate change is wreaking havoc on human health.

Glaciers are shrinking fast. Scientists are rushing to figure out how fast.

New research suggests that the world's glaciers are disappearing more quickly than scientists previously estimated.

How climate change is fueling hurricanes like Ida

Hurricane Ida rapidly gained strength right before it hit Louisiana this weekend. Abnormally hot water in the Gulf of Mexico acted as fuel for the storm.

A major report warns climate change is accelerating and humans must cut emissions now

The U.N. has released the most comprehensive global climate science report ever. It is unequivocal: Humans must stop burning fossil fuels or suffer catastrophic impacts.

Earth is barreling toward 1.5 degrees Celsius of warming, scientists warn

Scientists say humans must keep global temperatures from increasing more than 1.5 degrees Celsius. The World Meteorological Organization warns that number is looming.
