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.

When a huge floating gyre of plastic waste was discovered in the Pacific in the late 1980s, people were shocked. When whales died and washed ashore with stomachs full of plastic, people were horrified. When photographs of beaches under knee-deep carpets of plastic trash were published, people were disgusted.

Though some of it came from ships, most, presumably, was from land. But how much was coming from where?

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.

For the first time, scientists have videotaped sharks traveling a 500-mile-long "shark highway" in the Pacific, and they plan to turn it into a protected wildlife corridor in the ocean.

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.

The oceans are getting warmer and fish are noticing. Many that live along U.S. coastlines are moving to cooler water. New research predicts that will continue, with potentially serious consequences for the fishing industry.

Hurricane Harvey, which devastated South Texas last August, was powered by what scientists say were the highest ocean temperatures they've ever seen in the Gulf of Mexico.

When it comes to motherhood, at least if you're a fish, big is better. Bigger fish produce more far more offspring pound for pound than smaller fish. And that can mean more on your plate.

The new research comes from a team in Australia and Panama and reinforces fishing practices that protect larger fish as well as marine protected areas, which are like fish "sanctuaries" in the ocean.

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.

Over the past 125,000 years, the average size of mammals on the Earth has shrunk. And humans are to blame.

That's the conclusion of a new study of the fossil record by paleo-biologist Felisa Smith of the University of New Mexico.

An environmental organization has unveiled plans to monitor a potent greenhouse gas from space.

The Environmental Defense Fund says it will launch a satellite to monitor methane with unprecedented precision.

Steven Hamburg, a climate scientist at EDF, says methane has many times the warming "potential" as the other more abundant greenhouse gas, carbon dioxide.
