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.

The government organization charged with keeping nuclear power safe is having a meltdown. The Nuclear Regulatory Commission consists of five commissioners who direct the work of hundreds of nuclear engineers and other experts. They write the rules for how nuclear reactors operate.

Now four of those commissioners say the chairman of the NRC is a bully who's destroying their ability to do their job.

Some climate strategists are looking beyond the United Nations and the idea of remaking the energy economy — and toward the world's tropical forests.

The basic idea is to provide rich countries that emit lots of climate-warming gases another way to reduce their carbon footprint besides replacing or retrofitting factories and power plants. Instead, they could just pay poorer countries to keep their forests, or even expand them. Forests suck carbon out of the atmosphere. It's like paying someone to put carbon in a storehouse.

In archaeology, you get special bragging rights when you can lay claim to the oldest specimen of something.

Scientists in South Africa may now qualify for what they say is the world's oldest bed. Well, not a bed exactly, but more like a mattress made of grass.

What Lyn Wadley, an archaeologist at the University of Witswatersrand, found were mats of grass and sedge piled half an inch thick on the floor of a cavelike rock shelter in South Africa.

Second of a two-part series on California's climate policies. Read part 1.

Climate experts are exploring the concept of growing dense fields of weeds to help soak up carbon dioxide from the atmosphere.

Just over a year from now, California will begin enforcing a set of laws that limit emissions of greenhouse gases from factories, power plants and, eventually, from vehicles.

California is about to try a radical experiment. A little over a year from now, the state will limit the greenhouse gas emissions from factories and power plants, and, eventually, emissions from vehicles.

The U.S. Congress tried to pass a similar plan for the whole country but dropped the idea last year.

In 1977, a small crew of oceanographers traveled to the bottom of the Pacific Ocean and stumbled across a brand new form of life. The discovery was so unusual, it turned biology on its head and brought into question much of what scientists thought they knew about where life can form and what it needs in order to survive.

A scientist in Boston has been driving around the city measuring leaks in the gas mains. He's found a lot, and he wants the public to know where they are.

Gas leaks aren't uncommon, and gas companies spend a lot of time tracking them down and repairing them. But the scientific team says they're surprised at how many they've found, and what those leaks are doing to the health of the city's trees.

A law passed after the Exxon Valdez oil spill requires the government to assess the biological damage from big spills so fines can be fixed and damage paid for. The National Academy of Sciences has a report describing the methods and metrics of determining the "ecosystem services" that have been lost due to the BP oil spill in the Gulf of Mexico.

The planet may not feel any different today, but there are now 7 billion people on it, according to the United Nations.

That number will continue to rise, of course, and global incomes are likely to rise as well. That means more cars and computers, and bigger homes: the kinds of things Americans take for granted. It's that rise in consumption that has population experts worried.

Environmental hazards sicken or kill millions of people — soot or smog in the air, for example, or pollutants in drinking water. But the most dangerous stuff happens where the food is made — in peoples' kitchens.

That's according to the World Health Organization, which says that the smoke and gases from cooking fires in the world's poorest countries contribute to nearly two million deaths a year — that's more than malaria.
