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.

Brazil is a paradise for birds; the country has more than 1,700 species. Among them is the colorful toucan, a bird with an almost comically giant bill that can be half as long as its body. There are lots of different types of toucan — red-breasted, channel-billed, keel-billed, saffron toucanet — each with its own color-scheme and distinctive call.

With Rising Seas, America's Birthplace Could Disappear

By the end of the century, the birthplace of America may be underwater.

The first successful English colony in America was at Jamestown, Va., a swampy island in the Chesapeake Bay. The colony endured for almost a century, and remnants of the place still exist. You can go there and see the ruins. You can walk where Capt. John Smith and Pocahontas walked. But Jamestown is now threatened by rising sea levels that scientists say could submerge the island by century's end.

Bones Tell Tale Of Desperation Among The Starving At Jamestown

Originally published on Wed May 1, 2013 7:48 pm

The four cuts at the top of this skull "are clear chops to the forehead," says Smithsonian forensic anthropologist Douglas Owsley. Based on forensic evidence, researchers think the blows were made after the person died.

"First they ate their horses, and then fed upon their dogs and cats, as well as rats, mice and snakes."

So says James Horn of the historical group Colonial Williamsburg, paraphrasing an account by colony leader George Percy of what conditions were like for the hundreds of men and women stranded in Jamestown, Va., with little food in the dead of winter in 1609.

They even ate their shoes. And, apparently, at least one person.

How Doctors Would Know If Syrians Were Hit With Nerve Gas

Originally published on Wed May 1, 2013 12:02 pm

Doctors at a hospital in Aleppo, Syria, treat a boy injured in what the government said was a chemical weapons attack on March 19. Syria's government and rebels accused each other of firing a rocket loaded with chemical agents outside of Aleppo.

President Obama affirmed Tuesday that there's evidence Syrians have been attacked with chemical weapons — in particular, nerve gas.

But that's not the same as proof positive.

"We don't know how they were used, when they were used, who used them," Obama said. "We don't have a chain of custody that establishes what exactly happened."

What's Behind The 'Fairy Circles' That Dot West Africa?

Thousands of "fairy circles" dot the landscape of the NamibRand Nature Reserve in Namibia. Why these barren circles appear in grassland areas has puzzled scientists for years.

There's a mystery in West Africa that's puzzled scientists for years. Strange circles of bare soil appear in grassland; they're commonly called "fairy circles." These naturally occurring shapes last for decades, until the grass eventually takes over and the circles fade.

Now German scientists think they have an explanation — a horde of insects seems to be bioengineering thousands of miles of desert.

Wind power is growing faster than ever — almost half of the new sources of electricity added to the U.S. power grid last year were wind farms.

But is the sky the limit? Several scientists now say it's actually possible to have so many turbines that they start to lose power. They steal each other's wind.

Could Tapping Undersea Methane Lead To A New Gas Boom?

Originally published on Fri March 15, 2013 10:38 am

This photo from a Kyodo News helicopter shows a flame of natural gas from a Japanese deep-sea drilling ship on Tuesday. This successful extraction of methane from the seafloor was a world first.

The new boom in natural gas from shale has changed the energy economy of the United States. But there's another giant reservoir of natural gas that lies under the ocean floor that, theoretically, could dwarf the shale boom.

No one had tapped this gas from the seabed until this week, when Japanese engineers pulled some up through a well from under the Pacific. The gas at issue here is called methane hydrate. Methane is natural gas; hydrate means there's water in it. In this case, the molecules of gas are trapped inside a sort of cage of water molecules.

Past Century's Global Temperature Change Is Fastest On Record

Originally published on Fri March 8, 2013 10:40 pm

Scientists say they have put together a record of global temperatures dating back to the end of the last ice age, about 11,000 years ago. This historical artwork of the last ice age was made by Swiss geologist and naturalist Oswald Heer.

There's plenty of evidence that the climate has warmed up over the past century, and climate scientists know this has happened throughout the history of the planet. But they want to know more about how this warming is different.

Now a research team says it has some new answers. It has put together a record of global temperatures going back to the end of the last ice age — about 11,000 years ago — when mammoths and saber-tooth cats roamed the planet. The study confirms that what we're seeing now is unprecedented.

The way Americans get their electricity is changing. Coal is in decline. Natural gas is bursting out of the ground in record amounts. And the use of wind and solar energy is growing fast. All this is happening as power companies are trying to choose which kind of energy to bet on for the next several decades.

Until recently, half of these plants burned coal to make electricity. Now, that's down to about one-third. Since 2010, about 150 coal plants either have been retired or it's been announced they will be retired soon.

Since the drubbing that Superstorm Sandy gave the Northeast in November, there's a new sense of urgency in U.S. coastal cities. Even though scientists can't predict the next big hurricane, they're confident that a warmer climate is likely to make Atlantic storms bigger and cause more flooding.

Cities like Boston are in the bull's-eye.

Congress has now agreed to give some $60 billion to states damaged by Hurricane Sandy. A lot will go to Long Island, one of the hardest hit areas. Besides damages to homes and businesses, its system of protective barrier islands and beaches were partially washed away.

Scientists are trying to find out where that sand and sediment went, and whether it can be used to rebuild Long Island's defenses.

Boeing announced late Friday that it is postponing deliveries of its new 787 Dreamliner because of problems with its big batteries. Aviation authorities in the U.S. and abroad grounded the new jetliners after those batteries failed in two planes operated by Japanese airlines, including one battery that burned while the plane was on the ground.

These lithium-ion batteries are new to jetliners. They're powerful and lightweight, and, unfortunately, they're also fragile.

It will take tens of billions of dollars to repair the damage wrought by Superstorm Sandy. But scientists who study climate change say repair is not enough. As the climate warms, ice sheets and glaciers will melt, raising the sea level. That means coastal storms will more likely cause flooding.

So New Yorkers, local politicians and scientists face a tough decision: How to spend limited funds to defend themselves from what climate experts call "the new normal."
