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.

In January, we published a special report called "A New Weapon In The War Against Plastic Waste." It profiled Froilan Grate, a Filipino environmental activist, and his efforts to fight the non-recyclable plastic waste that is clogging miles and miles of coastline in the Philippines.

Once again, the world was unusually hot in 2018. In fact, on average it was the fourth-hottest year around the planet since modern record-keeping began in 1880.

If a warming planet were an Olympic sport, fourth wouldn't make the podium. But consider the context: The hottest five years on record are, in fact, the last five years. The year 2016, which was 1.69 degrees Fahrenheit warmer than the 20th-century average, holds the top spot, with 2018 at 1.42 degrees F warmer.

A diver in California has stumbled on an unexpected source of plastic waste in the ocean: golf balls.

As the balls degrade, they can emit toxic chemicals. And there appear to be lots of them in certain places underwater — right next to coastal golf courses.

Try this: Write a list of every piece of plastic you touch in a day.

I did it. I stopped counting at 56 items.

Plastic is to our time what wood was for millennia. But unlike wood, most plastic doesn't go away. It ends up as trash in streets, rivers, lakes and oceans. It breaks down into microplastic — particles a tenth of an inch or smaller — and gets into our food and water. The health effects are largely unknown.

2018 was a hot year — in fact, the fourth warmest on record. The only years that were, on average, warmer were the past three, according to the World Meteorological Organization.

It has been warming for decades now. But 2018 brought several major new and markedly more precise reports from scientists about what climate change is doing to the weather and how dire they expect the consequences to be.

That didn't stop President Trump and others from continuing to question the evidence.

As climate negotiators from around the world meet in Poland this week and next to figure out how to keep greenhouse gases out of the atmosphere, they are hearing some discouraging news: Emissions of the biggest pollutant, carbon dioxide, are going up.

For three years — 2014 through 2016 — the amount of atmospheric CO2 had leveled off. But it started to climb again in 2017, and is still rising.

"Last year, we thought, was a blip — but it isn't," says Rob Jackson, a climate scientist at Stanford University in California.
