Christopher Joyce

Christopher Joyce is a correspondent on the science desk at NPR. His stories can be heard on all of NPR's news programs, including NPR's Morning Edition, All Things Considered, and Weekend Edition.

Joyce seeks out stories in some of the world's most inaccessible places. He has reported from remote villages in the Amazon and Central American rainforests, Tibetan outposts in the mountains of western China, and the bottom of an abandoned copper mine in Michigan's Upper Peninsula. Over the course of his career, Joyce has written stories about volcanoes, hurricanes, human evolution, tagging giant blue-fin tuna, climate change, wars in Kosovo and Iraq and the artificial insemination of an African elephant.

For several years, Joyce was an editor and correspondent for NPR's Radio Expeditions, a documentary program on natural history and disappearing cultures produced in collaboration with the National Geographic Society that was heard frequently on Morning Edition.

Joyce came to NPR in 1993 as a part-time editor while finishing a book about tropical rainforests and, as he says, "I just fell in love with radio." For two years, Joyce worked on NPR's national desk and was responsible for NPR's Western coverage. But his interest in science and technology soon launched him into parallel work on NPR's science desk.

In addition, Joyce has written two non-fiction books on scientific topics for the popular market: Witnesses from the Grave: The Stories Bones Tell (with co-author Eric Stover); and Earthly Goods: Medicine-Hunting in the Rainforest.

Before coming to NPR, Joyce worked for ten years as the U.S. correspondent and editor for the British weekly magazine New Scientist.

Joyce's stories on forensic investigations into the massacres in Kosovo and Bosnia were part of NPR's war coverage that won a 1999 Overseas Press Club award. He was part of the Radio Expeditions reporting and editing team that won the 2001 Alfred I. duPont-Columbia University journalism award and the 2001 Sigma Delta Chi award from the Society of Professional Journalists. Joyce won the 2001 American Association for the Advancement of Science excellence in journalism award.

The Arctic is a huge, icy cap on the planet that acts like a global air conditioner. But the air conditioner is breaking down, according to scientists who issued a grim "report card" on the Arctic on Tuesday.

They say the North Pole continues to warm at an alarming pace — twice the rate as the rest of the planet, on average. This year was the Arctic's second-warmest in at least 1,500 years, after 2016.

With the 2017 Atlantic hurricane season finally over, scientists are taking stock of what they say was a monumental year.

A total of 10 hurricanes swept the region. Six were major storms of Category 3 or higher, and three of those were Category 4 or higher when they made landfall, spreading havoc from the Caribbean to Texas.

The Atlantic Ocean is vast and has always made its own weather. But a typical year sees about six hurricanes, not 10. And three strong hurricanes hitting land — Harvey, Irma and Maria — is extraordinary.

So what's going on?

The world's oceans are rising. Over the past century, they're up an average of about eight inches. But the seas are rising more in some places than others. And scientists are now finding that how much sea level rises in, say, New York City, has a lot to do with exactly where the ice is melting.

A warming climate is melting a lot of glaciers and ice sheets on land. That means more water rolling down into the oceans.

But the oceans are not like a bathtub. The water doesn't rise uniformly.

After Hurricane Harvey, some Texas residents, politicians and scientists are wondering whether the whole U.S. system for predicting floods is any good.

The storm's deluge flooded parts of southeast Texas that had rarely, or never, been underwater before. Some areas got more than 50 inches of rain in a few days. "When the numbers started coming in it was a little scary," says Matt Zeve, the director of operations for the Harris County Flood Control District, which includes Houston.

Governments are wrapping up a meeting in Bonn, Germany, to figure out how to implement a global climate agreement.

The conference has focused on the pledges to reduce greenhouse gas emissions, which nations made two years ago in Paris. But even as negotiators debate the details, scientists are warning that carbon dioxide levels are again on the rise, and the efforts in Paris may not be enough.
