Flood experts all use the same language to convey risk: 10-year floods, 100-year floods, 500-year floods. But those intervals are often misunderstood, and climate change is making them less accurate.

Scientists recommend the start of a geological epoch defined by how humans have impacted Earth — soot, plastics and radioactive fallout have made it into the rocks, ice and mud that form our planet.

Some of the hottest global weather in recorded history is happening this week. It's likely that record temperatures will continue to occur this year.

Some of the hottest global weather in recorded history is happening this week. It's likely that records will continue to fall this year.

A new satellite will take continuous measurements of dangerous air pollution in the U.S. That has scientists, and residents, warily optimistic about undoing decades of environmental injustice.

Researchers looked at thousands of homeowners who moved out of flood-prone homes. Most stayed within a 20-minute drive, and their new homes were safer from flooding.

The natural climate pattern known as El Niño has officially begun. It exacerbates human-caused climate change, driving even hotter temperatures and other dangerous weather.

Climate change is causing hurricanes to get more powerful and dangerous. Scientists weigh in on what that means for forecasts, emergency officials and you.

The National Hurricane Center is upgrading the computer models it uses to predict storm surge. People will be able to see maps about how much storm surge is predicted when a storm is headed their way.

El Niño is coming, which usually means fewer storms. But abnormally warm ocean water makes hurricanes more likely. It's a rare situation

The giant storm formed over abnormally warm water in the Pacific. And sea level rise makes storm surge even more dangerous to residents of Guam and the Mariana Islands.

Floods, wildfires, heat waves and hurricanes cause billions of dollars of property damage each year. Can federal climate scientists help the insurance industry keep up?

Climate change is causing ice caps and glaciers to disappear. Reporters from NPR's Climate Desk talk about their stories connecting the dots between melting ice and our everyday lives.

An estimated 15 million people are threatened by floods that happen when glaciers melt rapidly. Nepal's Himalayan communities are on the front lines.

Melting glaciers are leaving behind unstable lakes around the world. Millions of people live downstream, in places increasingly threatened by deadly flash floods. What will it take to protect them?

Melting glaciers and ice sheets are far from where most people live. But the impacts stretch across the planet. See if you can guess how.

Ice in Antarctica is melting rapidly. That's driving sea level rise around the world. But some places are threatened more than others, and Texas is in the crosshairs.

Galveston, Texas, has some of the fastest sea level rise in the world. To protect the city, engineers need to know how fast ice in West Antarctica will melt. Scientists are racing to figure it out.

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.

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.
