The Arctic is very sensitive to climate change. In the last 40 years, the region has warmed much more rapidly than the Earth as a whole, a new study finds.

As the Earth heats up, heavy rain is getting more common across the United States. That means more severe floods happen more often.

Climate change means more rain and higher seas, which adds up to more flooded homes. Even a small amount of water indoors can cost a lot.

Most Americans have recently been affected by extreme weather and support efforts to protect against future disasters, a new survey finds. And many people suffer long-term financial problems.

Federal forecasters expect more hurricanes than usual this year. Climate change is driving larger, more destructive storms. This is the seventh year in a row with an above-average forecast.

Burning oil, coal and other fossil fuels releases plumes of tiny, dangerous particles. A new study estimates that eliminating that pollution would save about 50,000 lives in the U.S. each year.

The U.S. promised to slash its emissions and send tens of billions of dollars to low-lying and less well-off nations. The war in Ukraine is delaying that even as the toll from climate change rises.

Iraq's capital city is already seeing record heat — up to 125 degrees Fahrenheit. A report predicts more 120-plus degree days to come. And the "urban heat island" effect will make things even worse.

Some ecosystems have already been irreversibly altered, scientists say. And climate change is wreaking havoc on human health.

Arctic communities have long been plagued by soot that drives snow melt and respiratory disease. Now, humans are making their mark in Antarctica.

Sea levels are rising even faster on the East Coast and Gulf Coast. And advances in climate science mean we can see the future clearly for the first time.

The case brought by Baltimore is one of more than 20 similar lawsuits nationwide that seek to hold fossil fuel companies accountable for their role in climate change.

Carbon offsets got a big boost from November's U.N. climate summit. New rules could make it easier for companies to pay for carbon-cutting projects in other countries, rather than doing it themselves.

Photographer Vlad Sokhin's latest work, Warm Waters, is an exploration of climate change traveling across 18 countries and off-the-map territories seen by seldom few.
