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.

Panel Charts Path To New Home For Nuclear Waste

Without a centralized national repository for nuclear waste, the radioactive material is currently being kept at various sites across the country. Above, large concrete canisters, each holding 14 55-gallon drums of waste, are loaded on a truck in Richland, Wash., in June 2005 where they were later shipped to a facility in New Mexico.

A panel of experts today set forth a plan for getting rid of thousands of tons of highly radioactive nuclear waste.

Most of it is spent fuel from nuclear power reactors. It was supposed to go to a repository in Nevada called Yucca Mountain, but the government has abandoned that plan.

Is The Booming Natural Gas Industry Overproducing?

Originally published on Wed January 25, 2012 10:25 am

Hydraulic fracturing wells have been producing a tremendous amount of natural gas — far more than the current demand. Above, a Cabot Oil & Gas natural gas drill at a fracking site in South Montrose, Pa.

The practice of hydraulic fracturing — pumping fluid into underground rock to push up natural gas — has its detractors, especially among environmentalists. But it's becoming clear that whatever its drawbacks, "fracking," as it's called, is producing a lot of gas — maybe too much gas.

Fracking was once a small part of the natural gas industry, a technique to get hard-to-reach deposits in underground shale. Then the technology improved, and the dinner bell rang. Everybody wanted in. Now there's so much gas on the market that the price is at a 10-year low.

Cheap Chinese Panels Spark Solar Power Trade War

Originally published on Thu January 19, 2012 8:36 am

Contractors with SunEdison install more than 1,000 Chinese-made solar panels on top of a Kohl's Department Store in Hamilton Township, N.J., in 2010. Energy generated by the solar system will cut the store's usage, on average, by 25 to 30 percent.

There's a solar trade war going on inside the U.S., sparked by an invasion of inexpensive imports from China.

The U.S. solar industry is divided over these imports: Panel-makers say their business is suffering and want a tariff slapped on the imports. But other parts of the industry say these cheap panels are driving a solar boom in the U.S.

Politically, climate change is off this year's campaign agenda. Jobs, the economy and social issues are front and center.

But scientists are working as hard as ever to figure out how much the Earth is warming and what to do about it. Some now say it's time for a new strategy, one that gets faster results.

Talk to Durwood Zaelke, for example. Zaelke is a grizzled veteran of the climate wars: He was in Kyoto in 1997 when the world's nations drafted a treaty promising to curb warming, and he has watched that promise fizzle while the planet's temperature continues to rise.

How Fracking Wastewater Is Tied To Quakes

Originally published on Thu January 5, 2012 1:00 pm

With the skyline of Youngstown, Ohio, in the distance, a brine injection well owned by Northstar Disposal Services LLC is seen in Youngstown on Jan. 4. The company has halted operations at the well, which disposes of brine used in gas and oil drilling, after a series of small earthquakes hit the Youngstown area.

Small earthquakes in Ohio and Arkansas associated with hydraulic fracturing for natural gas have taken many people by surprise. Gas industry executives say there's no hard evidence that their activities are causing these quakes. But some scientists say it's certainly possible; in fact, people have been causing quakes for years.

In the 1960s, geologists realized that gold mines in South Africa had created small earthquakes. Caverns dug into the earth thousands of feet below the surface collapsed. The "pancake" effect caused quakes — in one case a magnitude-5.2 temblor.

Double-Blind Violin Test: Can You Pick The Strad?

Originally published on Mon January 2, 2012 7:53 pm

In a double-blind test by professional violinists, most couldn't determine — by sound alone — which violin was an original Stradivarius and which was a modern instrument. Above, a 1729 Stradivari known as the "Solomon, Ex-Lambert."

In the world of violins, the names Stradivari and Guarneri are sacred. For three centuries, violin-makers and scientists have studied the instruments made by these Italian craftsmen. So far no one has figured out what makes their sound different. But a new study now suggests maybe they aren't so different after all.

OK, here's a test. Clip one is a musical phrase from Tchaikovsky's Violin Concerto in D Major. Clip two is the same phrase. The same musician plays both. But one is on a Stradivarius violin, the other on a violin made in 1980. See if you can tell the difference.

On Florida's Gulf coast Tuesday, there will be a celebrated homecoming. For a turtle. This is no ordinary turtle: Known as Johnny Vasco da Gama, after the 15th-century Portuguese explorer, it crossed the Atlantic twice — by sea and by air.

Johnny, as his human friends call him, is a critically endangered Kemp's ridley turtle. Only a few thousand of these sea-turtles exist, mostly in the Gulf of Mexico. Normally, they do not migrate across the Atlantic.

This year has something unpleasant in common with the years 1979 and 1986. In 1979, a nuclear reactor at Three Mile Island in Pennsylvania melted down. In 1986, the Soviet reactor at Chernobyl blew up and burned.

This year's meltdown occurred in Fukushima in Japan, and nuclear power isn't likely to be the same as a result.

Nuclear power had enjoyed 25 years of relative quiet, but the Fukushima accident reminded people that despite improvements in safety, nuclear plants could still go horribly wrong.

For some, though, nothing has changed much.

Turbulence As Europe Passes Fee On Plane Emissions

Air travel contributes only 2 to 4 percent of carbon dioxide emissions worldwide. A new ruling says airlines flying into an out of European airports will have to pay a price for the carbon dioxide they emit from burning jet fuel. Above, a plane takes off from the Geneva airport on March 11, 2010.

A European court ruled Wednesday that airlines flying into and out of European airports will have to pay a price for the carbon dioxide they emit when they burn jet fuel.

U.S. airlines, which had been fighting the idea in court, say the European Union is trying to force other countries to reduce carbon emissions. Europe currently limits carbon dioxide emissions from its major industries to curb global warming. The ruling cannot be appealed, and the decision likely to end the dispute.

Climate Activists: To Cut Emissions, Focus On Forests

The world's forests act as massive sponges, sucking carbon from the atmosphere. Above, an aerial photo from 2009 shows massive deforestation in the Brazilian state of Para.

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.

Can 'Carbon Ranching' Offset Emissions In Calif.?

Tall grasses in the San Joaquin valley in California suck carbon dioxide out of the air and store it in the soil. It's one option that environmentalists are pursuing for greenhouse gas "offsets" that can be bought and sold in the state.

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.

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.

Boston's Leaky Gas Lines May Be Tough On The Trees

Nathan Phillips looks at methane data plotted on a map of Boston streets on Nov. 17. Data from a mobile methane "sniffer" and a GPS show a real-time display of the gas levels in Google Earth. The orange spike in the center of the screen, on St. Paul Street, indicates methane levels about two or three times above normal levels, Phillips says.
Robin Lubbock WBUR

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.

As Population, Consumption Rise, Builder Goes Small

Originally published on Wed November 2, 2011 10:33 am

The world's population has just hit 7 billion people and continues to grow. Population experts are concerned about the rise in consumption that will accompany the increase in people. One California home builder, ZETA Communities, designs and builds small, highly energy-efficient homes.

Zeta Communities

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.

In African Cave, An Early Human Paint Shop

This abalone shell was found with ocher and a grinding stone. The iron oxide was used as a pigment to paint bodies and walls, as well as to thicken glue.

Science/AAAS

Apparently one of the earliest human instincts was to paint things, including bodies and cave walls. That's the conclusion from scientists who have discovered something remarkable in a South African cave — a tool kit for making paint. It looks to be the oldest evidence of paint-making.

Over in southern Africa 100,000 years ago, Homo sapiens was pretty new on the scene. A favorite hangout was a cave named Blombos near the Southern ocean.
