Many Western states lack building codes for wildfire-resistant homes. But a new study finds the costs can be minimal, undercutting long-held building industry arguments against such codes.

Many people move without realizing the danger that wildfires pose to their new home. A new risk rating system could help buyers learn more on real estate sites.

California broke its record for renewable energy when solar and wind provided enough to meet all consumer demand. At the time, natural gas power plants were still on, a necessity for the grid.

With the climate warming rapidly, scientists are finding that cutting fossil fuels may not be enough. Carbon dioxide emissions may need to be vacuumed right out of the air.

The U.S. is making the largest investment in history in the country's water system. In the rush to spend, some worry green projects will be overlooked.

The good news is that the world has solutions and technology to slow climate change. The bad news is that time is running out.

Some corals have turned a ghostly white due to extreme heat stress. It's the fourth bleaching event on the Great Barrier Reef in the last seven years, which makes it harder to recover.

Australia's Great Barrier Reef is suffering another mass bleaching. That's when corals turn ghostly white due to heat, and it's becoming more common as the climate warms.

With smushed-in faces and compact bodies, bulldogs are prone to health problems. A court in Norway recently banned breeding them, sparking an international debate.

Allergy season is getting worse as the climate changes, according to new research. Hotter temperatures are causing some plants to produce more pollen.

A judge in Norway has banned the breeding of bulldogs. Their flat, smooshed faces can cause health problems. An animal rights group argued the breed is so unhealthy, it amounts to animal cruelty.

"Within seconds we realized, oh my God, a pack of killer whales is attacking a blue whale," researcher John Totterdell from the Cetacean Research Centre in Australia, told NPR.

It was once thought that nothing could take down the world's largest animal, the blue whale. But scientists have witnessed something unusual that shows these giants do have a predator to worry about.

Cities are experiencing heavier storms and flooding as the climate gets hotter. But due to outdated rainfall records, many are still building infrastructure for the climate of the past.

Cities will soon spend billions upgrading their water systems with federal infrastructure funds. But many don't have information about how to prepare the systems for climate change.

As the climate gets hotter, plants could need to move to new habitats. But animals that eat their fruit and help spread the seeds are disappearing.

As the climate gets hotter, plants may need to grow in new locations to survive. But the animals that help spread the seeds are disappearing.

A new climate report finds that 2021 was the sixth hottest year on record. The past decade has also been the hottest since record-keeping began.

Many of this year's deadly extreme weather is linked to climate change and scientists warn they're a sign of what's to come.
