This was the hottest July ever recorded on Earth, according to federal climate scientists. It's a stark reminder that humans are rapidly warming up the planet by burning fossil fuels.

The Atlantic hurricane season is now projected to have "above-normal level of activity" according to an updated forecast from the National Oceanic and Atmospheric Administration.

It's the middle of the winter in Antarctica, when the ocean around the continent freezes. But this year there's less sea ice than ever recorded.

Home insurance is becoming more expensive and increasingly difficult to get in states that are on the front lines of climate change. And some of the potential solutions aren't politically popular.

It's increasingly expensive and difficult to get home insurance, as losses rise from climate-driven disasters such as wildfires and hurricanes. And the solutions aren't always politically popular.

NOAA has announced its forecast for El Niño, as well as expectations for drought, heat and precipitation in the coming months. (This piece originally aired on ATC on July 20, 2023.)

El Niño is warming up the water in the Pacific Ocean. That extra heat affects the whole planet, and has helped drive record-breaking hot weather.

June 2023 was the hottest June on record, going back to 1850. And forecasters expect more records to fall as El Niño exacerbates human-caused climate change.

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.

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?
