Climate change makes deadly floods, like what happened in Libya, more likely. Floods in China, Greece and Brazil in recent weeks underscore the growing danger.

Four states are strengthening rules that require home sellers and landlords to disclose information about whether a home has flooded in the past, or is likely to flood in the future.

The Atlantic hurricane season begins Wednesday. This year, the National Hurricane Center is making a big upgrade to its forecasts, especially when it comes to storm surge.

Temperature records are falling left and right. Wildfires, hurricanes, heat waves and droughts are exacerbated by human-caused climate change.

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.
