WRUR 88.5 Different Radio

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.

An "atmospheric river" is a colorful term for a sinuous plume of moisture that travels up from the tropics — a single plume can carry more water than the Mississippi River at its mouth. But new research shows that atmospheric rivers are also among the most damaging weather systems around.

The atmospheric rivers that soaked California this winter did some good — they ended an epic drought in the state.

The Mariana Trench in the northern Pacific is the deepest part of the world's oceans. You might think a place that remote would be untouched by human activity.

But the Mariana Trench is polluted.

At its deepest — about 7 miles down — the water in the trench is near freezing. The pressure would crush a human like a bug. Scientists have only recently explored it.

This week, President Trump's transition team put new restrictions on government scientists' freedom to communicate. The restrictions are being characterized as temporary, and some have already been lifted.

There's more methane gas in the atmosphere than there used to be, by every scientific measure. The Obama administration has been trying to stem the increase of this powerful greenhouse gas, but the incoming Trump administration appears bent on keeping the government's hands off methane.

Almost a million elephants roamed Africa 25 years ago. Assessments of their population now vary but suggest there are fewer than half that many. The main reason for the decline is ivory. Despite a 1989 ban on ivory trade, poachers continue to kill elephants for their tusks.

Now China, the destination for most of that ivory, has announced it will shut down its domestic ivory market.

Scientists released this year's so-called Arctic Report Card on Tuesday, and it is a dismal one.

Researchers say the Arctic continues to warm up at rates they call "astonishing." They presented their findings at the American Geophysical Union's fall meeting in San Francisco.

Thousands of Earth scientists are in San Francisco this week to talk about climate change, volcanoes and earthquakes.

And another tectonic topic: President-elect Donald Trump.

As president, Trump will oversee a huge government scientific enterprise. Agencies like the National Oceanic and Atmospheric Administration and NASA have satellites collecting valuable data on the climate. Other agencies employ scientists studying that data, or modeling future climate shifts.

A single tornado can cause a lot of damage. But even worse are tornado outbreaks. Just this week, a cluster of at least 18 tornadoes struck the Southeast over two days.

Scientists are seeing bigger clusters in recent years, and they're struggling to figure out what's happening.

Imagine you're passing a fast-food restaurant and you smell hamburger on the grill. You're hungry, so you pull in and eat one ... and the foam box it comes in.

That's apparently what's happening with some oceanic birds. And now scientists think they know why.

The fact that sea animals and birds eat floating plastic has long puzzled biologists. Their best guess was that it looks like food. But the new evidence suggests that for a lot of birds, plastic actually smells like food.

During his campaign, Donald Trump called climate change a hoax. And he vowed to abandon the Paris climate agreement signed last year by President Obama and almost 200 countries.

It probably wouldn't be hard for Trump to dump the climate deal.
