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.

Scientists have uncovered a pit of human bones at a Civil War battlefield in Virginia. The remains are the amputated limbs of wounded Union soldiers.

It's the first "limb pit" from a Civil War battlefield to be excavated, and experts say it opens a new window on what is often overlooked in Civil War history: the aftermath of battle, the agony of survivors and the trials of early combat surgeons.

There's going to be a changing of the guard in space. On Tuesday, NASA is launching two new satellites, collectively called GRACE, to replace two that have been retired after 16 years in orbit.

New research suggests that global warming could cause temperature swings to get unusually extreme. And the regions where the biggest swings will occur are among the poorest in the world — and the least responsible for the greenhouse gas emissions that cause global warming.

Climate scientists already know that as the planet warms, there's a bigger chance of extreme weather: bigger hurricanes, for example, or heavier rainfall.

Predicting how climate change will alter the weather is becoming a flourishing business.

The consumers are property owners and businesses that fear a rise in extreme weather — hurricanes, floods or heat waves, for example. Last year set a record for U.S. losses at over $300 billion.

Tiny particles of plastic are showing up all over the world, floating in the ocean, buried in soil, in food and even in beer. Now there's new research that's found microplastics in fertilizer — organic fertilizer from food waste, in fact.

Collecting food waste to make fertilizer is a big deal in parts of Europe and is catching on in the U.S. But Ruth Freitag, a chemist at the University of Bayreuth in Germany, says there's a problem.

A lot of smart people spend a lot of time trying to predict how much oil and gas is going to come out of the ground in the future.

Lately, they've been getting it wrong.

"Unpredictability, measured as the frequency of extreme errors in ... projections, has increased in the most recent decade," according to an unusual new study by a team at Carnegie Mellon University that found analysts are getting worse at predicting both how much oil and gas will be produced and how much Americans will need.

Animals that live in the ocean communicate with sound — humpback whales, for example. But these voices could soon be drowned out by powerful sonic booms from vessels searching for oil and gas.

Before it got cold this winter, it was warm. Very warm. In fact, new data out Monday shows 2017 was the third warmest year recorded in the lower 48 states.

And it was also a smackdown year for weather disasters: 16 weather events each broke the billion-dollar barrier.

First, the heat. Last year was 2.6 degrees F warmer than the average year during the 20th century.
