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 But due to outdated rainfall records, many are still building infrastructure for the climate of the past.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.

Despite a year of increasing weather disasters, Biden's ambitious climate plans may be doomed in Congress.

Climate scientists warn that emissions need to fall quickly. Those cuts will be even tougher with the Build Back Better legislation shelved for the foreseeable future.

Intense climate negotiations in Glasgow, Scotland, brought about major breakthroughs and compromises, as world leaders sought to avert extreme climate change.

The U.N. secretary-general warns the main goal of limiting global warming is "on life support." But Glasgow negotiators are making modest progress in their final hours.

Extreme weather is costing developing countries billions of dollars in damage. So they're seeking compensation from wealthier countries that have done the most to cause climate change.

Some of the world's most vulnerable countries at the U.N. climate conference in Scotland are demanding compensation, and it's becoming a major sticking point in the negotiations.

Last month, the Muisyo family turned on the lights for the first time thanks to climate financing from rich countries. But the fund is falling short of its $100 billion goal to help poor countries.

Despite new pledges to cut emissions, the world is not on track to hit a key climate change target of limiting warming. Scientists warn a planet that heats up more than that will look very different.

At international climate talks, world leaders are trying to keep the world to 1.5 degrees Celsius of warming. Why is that number important, and what happens if the world gets hotter than that?

On Tuesday, countries at the global climate summit COP26 pledged to cut back on heat-trapping methane emissions and do more to fight deforestation.
