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.

Climate Change Worsens Coastal Flooding From High Tides

Originally published on Thu October 9, 2014 9:58 am

A wave of high tides is expected to hit much of the East Coast this week. These special tides — king tides — occur a few times a year when the moon's orbit brings it close to the Earth.

But scientists say that lately, even normal tides throughout the year are pushing water higher up onto land. And that's causing headaches for people who live along coastlines.

As Bob Dylan might have put it, the tides, they are a changin'.

Soil Doctors Hit Pay Dirt In Manhattan's Central Park

Manhattan's Central Park is surrounded by one of the densest cities on the planet. It's green enough, yet hardly the first place most people would think of as biologically rich.

But a team of scientists got a big surprise when they recently started digging there.

They were 10 soil ecologists — aka dirt doctors. Kelly Ramirez from Colorado State University was among them. "We met on the steps of the natural history museum at 7 a.m. with our collection gear, coolers and sunblock," she recalls.

When Can A Big Storm Or Drought Be Blamed On Climate Change?

Nowadays, when there's a killer heat wave or serious drought somewhere, people wonder: Is this climate change at work? It's a question scientists have struggled with for years. And now there's a new field of research that's providing some answers. It's called "attribution science" — a set of principles that allow scientists to determine when it's a change in climate that's altering weather events ... and when it isn't.

Crocodile Meets Godzilla — A Swimming Dino Bigger Than T. Rex

There once was a place on Earth so overrun with giant, meat-eating predators that even a Tyrannosaurus rex would have been nervous. One predator there was even bigger than T. rex, and scientists now say it's apparently the only aquatic dinosaur ever found.

The swimming monster is called Spinosaurus aegyptiacus. It was 50 feet long — longer than a school bus, and 9 feet longer than the biggest T. rex.

U.S. Gets Middling Marks On 2014 'State Of Birds' Report Card

Originally published on Wed September 10, 2014 11:30 am

"The State of the Birds" 2014 report found that red knots (above) and other shorebirds are among the most threatened groups in the U.S. More than half of U.S. shorebird species are on the report's Watch List — species that are currently endangered or at risk.
Gerrit Vyn The Smithsonian Institution

All is not well with the nation's birds. The most comprehensive study ever of birds in America is out today, and it says many populations are in steep decline, even as others are doing well.

The report, called "The State of the Birds," comes from the federal government, universities and conservation groups — 23 organizations that have spent years examining bird populations, as well as habitats where the various species live.

An Icy Solution To The Mystery Of The Slithering Stones

There's A Big Leak In America's Water Tower

The northern arm of the Rocky Mountains is sometimes called "the crown of the continent," and its jewels are glaciers and snowfields that irrigate large parts of North America during spring thaw.

But the region is getting warmer, even faster than the rest of the world. Scientists now say warming is scrambling the complex relationship between water and nature and could threaten some species with extinction as well as bring hardship to ranchers and farmers already suffering from prolonged drought.

Underwater Meadows Might Serve As Antacid For Acid Seas

UC Santa Barbara's Jay Lunden and Andrew Brinkman, a summer intern for NOAA, prepare to deploy an instrument that measures temperature and salinity throughout the water column, and collects water samples.

The world's oceans are changing — chemically changing. As people put more carbon dioxide into the atmosphere, the oceans absorb more of it, and that's making the water more acidic.

The effects are subtle in most places, but scientists say that if this continues, it could be a disaster for marine life.

Dance Of Human Evolution Was Herky-Jerky, Fossils Suggest

Originally published on Sat July 5, 2014 1:18 am

Our popular image of Homo erectus as the proto-guy who whose human-like traits all emerged at once needs overhauling, some anthropologists say.
Sylvain Entressangle Science Source

A trio of anthropologists has decided it's time to rewrite the story of human evolution.

That narrative has always been a work in progress, because almost every time scientists dig up a new fossil bone or a stone tool, it adds a new twist to the story. Discoveries lead to new arguments over the details of how we became who we are.

Maybe Dinosaurs Were A Coldblooded, Warmblooded Mix

Originally published on Thu June 26, 2014 5:23 am

Being a bit coldblooded has its charms, scientists say. A mammal the size of a T. rex, for example, would have to eat constantly to feed its supercharged metabolism — and would probably starve.
Publiphoto Science Source

If you go to a zoo on a cold day and watch the snakes, you'll see what it means to be coldblooded. Not much action going on — most reptiles and other coldblooded creatures take on the temperature of their surroundings, so they tend to be most sluggish when the outside temperature is cool. The monkeys, however, act like they've had one too many cappuccinos.

Scientists Find Africa's Longest Land Migration: Zebras' 350-Mile Trek

Originally published on Thu May 29, 2014 7:11 pm

Wildlife biologists have discovered the longest known terrestrial migration in Africa: some 350 miles across southern Africa by huge herds of zebras. Large mammal migration in Africa has generally been hindered by the subdivision and fencing of land. However, this one remains possible because it takes place in a unique, multi-country wildlife corridor.

Many parts of the U.S. have been getting warmer over the past several decades, and also experiencing persistent drought. Wildlife often can't adjust. Among the species that are struggling is one of the American West's most highly prized fish — the cutthroat trout.

In springtime, you can find young cutthroats in the tiny streams of Montana's Shields Basin. Bend over and look closely and you might see a 2-inch fish wriggling out from under a submerged rock — the spawn of native cutthroats.
