Evan Fricke knows exactly how long it takes, after a bird on the island of Saipan eats a piece of fruit, for it to come out the other end (Answer: as little as 10 minutes).

"There's always this poop angle to my research," says Fricke, an ecologist with Rice University. "PhD in bird poop basically."

2021 was the sixth hottest year on Earth since record-keeping began. That is according to a new federal report out today. But climate scientists say the bigger concern is that it's part of an extremely hot decade. NPR's Lauren Sommer has more.

With billions of dollars for clean energy, the Build Back Better legislation has the potential to substantially and rapidly cut heat-trapping emissions in the U.S. But Sen. Joe Manchin, D-W.Va., rejected the bill on Sunday, and that means Build Back Better is effectively dead at a time when scientists say the world can't afford to wait on climate change.

At a small house outside of Nairobi, Kenya, a big event took place on a late October afternoon — one that also has big repercussions for climate change. Winifred Mumbua Muisyo got electricity at her home for the first time.

At 22 years old, Hilda Flavia Nakabuye stepped onto a very big stage. The audience was filled with hundreds of international delegates attending the 2019 United Nations Climate Change Conference, where countries were hashing out efforts to slow climate change.

Leaders from around the world are gathering in Glasgow, Scotland, to hammer out new pledges to fight climate change. The stakes are high. Scientists warn that heat-trapping emissions must fall dramatically by 2030. Otherwise, the world faces more extreme hurricanes, floods and droughts, likely displacing millions of people. Still, negotiations at the COP26 meeting are expected to be tough. Here are four reasons why.

Next week, world leaders meet to negotiate new climate agreements - high stakes for developing countries. Many contribute little to climate change but are severely affected by it. NPR's Lauren Sommer talked to a young activist from Uganda.

Being seven months pregnant is not exactly comfortable. Then there's being seven months pregnant in 110-degree heat with a broken air conditioner.

"It was the most challenging time," says Keishell Brown, a pregnant mother in Fresno, Calif. "It was very hard to sleep. There's no cool air coming. The fan is just blowing hot air."

On a hot afternoon in California's Sequoia National Park, Alexis Bernal squints up at the top of a 200-foot-tall tree.

"That is what we would call a real giant sequoia monarch," she says. "It's massive."

At 40 feet in diameter, the tree easily meets the definition of a monarch, the name given to the largest sequoias. It's likely more than 1,500 years old.

Still, that's as old as this tree will get. The trunk is pitch black, the char reaching almost all the way to the top. Not a single green branch is visible.

With tens of thousands of people displaced by floods, wildfires and hurricanes this summer, researchers warn that the majority of untapped fossil fuels must remain in the ground to avoid even more extreme weather.

The rapidly warming climate is the "greatest threat" to global public health, more than 200 medical journals are warning in an unprecedented joint statement that urges world leaders to cut heat-trapping emissions to avoid "catastrophic harm to health that will be impossible to reverse."

In early May, flames began to spread through a pine forest, consuming a dense carpet of leaves and underbrush. The burn was the definition of a "good fire," intentionally ignited to clear vegetation that could fuel future infernos.

It happened in the state leading the nation in controlled burns: Florida.

Coastal cities need billions of dollars to build defenses against sea level rise. Tensions are rising over where that funding will come from: taxpayers or private companies with waterfront property?
