At global climate negotiations, developing countries say they're being devastated by a problem they didn't cause. So they're looking for compensation for the losses and damage from climate change.

World leaders are meeting in Egypt for the next two weeks to talk about reining in climate change and paying for its deadly effects. Here's what you need to know.

The world is set to start crucial climate change negotiations soon. To avoid extreme warming, nations have to make deep cuts in heat-trapping emissions, fast.

Scientists are finding that Western wildfires can have far-reaching impacts. If they're burning while Central U.S. thunderstorms are forming, the rain and hail can be dramatically more destructive.

Unprecedented heat waves are on the rise as the climate gets hotter. But experts say the country's heat warning system may be leading the public to underestimate the dangers.

Extreme weather which is fueled by climate change is posing a bigger and bigger threat to the nation's water infrastructure.

Our bodies couldn't endure the summer heat without sweating. But as the climate gets hotter, sweat isn't cooling us off like it used to.

As record-breaking heat scorches the West, some disaster experts say our warning system may not be enough. Many people aren't getting alerted when heat can be deadly.

President Biden has signed the Inflation Reduction Act into law. We take a look at the viability of the law's provision concerning capturing carbon emissions.

Many communities are still rebuilding after wildfires in recent years, but few states require homes to be built with wildfire-resistant materials. A new study shows it's not as expensive as some say.

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.
