Starfish Blamed For Great Barrier Reef Coral Loss

Originally published on Fri October 5, 2012 1:03 pm

Over the past 27 years, Australia's Great Barrier Reef has lost half of its live coral cover, and a type of starfish is partly to blame for the alarming decline. Mark Eakin, head of NOAA's Coral Reef Watch program, discusses how to save the world's largest coral reef system.

A Tiny Ocean World With A Mighty Important Future

Plankton make up 98 percent of the biomass of ocean life and provide half of the oxygen on the planet. Scientists are working to figure out how climate change may be affecting these important microorganisms.

As you take in your next breath of air, you can thank a form of microscopic marine life known as plankton.

They are so small as to be invisible, but taken together, actually dwarf massive creatures like whales. Plankton make up 98 percent of the biomass of ocean life.

"This invisible forest generates half of the oxygen generated on the planet," Chris Bowler, a marine biologist, tells Guy Raz, host of weekends on All Things Considered.

And, as climate change alters the temperature and acidity of our waters, this mysterious ocean world may be in jeopardy.

Scientist Cleared In Polar Bear Controversy

Polar bears in the Beaufort Sea in northern Alaska. Scientist Charles Monnett caused a stir with a 2006 report on polar bears that were drowning, apparently owing to a lack of ice.

A long, controversial investigation of a polar bear scientist has ended with his government employer saying it does not look like he engaged in any scientific misconduct.

Charles Monnett is a wildlife researcher with the Bureau of Ocean Energy Management, part of the Department of the Interior. He and a colleague, Jeffrey Gleason, wrote an influential 2006 report describing apparently drowned polar bears floating in the Arctic, which they saw during a routine aerial survey of whales.

Despite Record Drought, Farmers Expect Banner Year

With far less than half of their normal corn yield, the Ulrich brothers are relying in part on government-subsidized crop insurance to keep their farm afloat.

After one of the driest summers on record, recent rains have helped in some parts of the country. But overall, the drought has still intensified. The latest tracking classifies more than a fifth of the contiguous United States in "extreme or exceptional" drought, the worst ratings.

In some parts of the Lower Midwest, water-starved crops have collapsed, but the farmers have not. Farmers across the country are surviving, and many are even thriving. This year, despite the dismal season, farmers stand to make exceptionally good money, according to the U.S. Department of Agriculture.

Tourists Banned From India's Tiger Reserves

Can tigers and tourists coexist? The debate is rumbling through India, where the Supreme Court has temporarily banned tourism in core areas of the country's 41 tiger reserves. The unexpected and controversial ruling is aimed at protecting the last of India's 1,700 tigers.

Up until the late 1960s, big game hunters trod the forests of Rajasthan's Ranthambore National Park, part of a sprawling tiger reserve southwest of Delhi. Under the court's recent ban, spotting one of India's big cats — a tiger or the more elusive leopard — inside the park is forbidden.

Bolivia's Cerro Rico: The Mountain That Eats Men

Cerro Rico, or Rich Mountain, rises like a monument in Potosi, Bolivia. It has produced silver, and hardship, for centuries. Now it may be in danger of collapse.
Carlos Villalon for NPR

Originally published on Tue September 25, 2012 7:39 pm

Near the mountain city of Potosi in the southern highlands of Bolivia, the cone-shaped peak of Cerro Rico stands as a 15,800-foot monument to the tragedies of Spanish conquest. For centuries, Indian slaves mined the mountain's silver in brutal conditions to bankroll the Spanish empire.

Today, the descendants of those slaves run the mines. But hundreds of years of mining have left the mountain porous and unstable, and experts say it is in danger of collapsing.

As Arctic Ice Melts, So Does The Snow, And Quickly

Researchers say that springtime snow is melting in the Arctic even faster than Arctic ice. That means less sunlight is reflected off the surface. Bare land absorbs more solar energy, which can contribute to rising temperatures on Earth. Above, a musher races along the Iditarod in the Alaskan tundra in 2007.

Arctic sea ice is in sharp decline this year: Last week, scientists announced that it hit the lowest point ever measured, shattering the previous record.

But it turns out that's not the most dramatic change in the Arctic. A study by Canadian researchers finds that springtime snow is melting away even faster than Arctic ice. That also has profound implications for the Earth's climate.

Getting A More Svelte Salmon To Your Dinner Plate

When it comes to farm raised fish, it doesn't pay to let them be lazy. Fish like wild salmon, tuna and eel are built for the vigorous swimming required during migration.

These fish are "uniquely adapted to a physiology of high levels of exercise performance," says Tony Farrell, who studies fish physiology in the University of British Columbia Zoology department. "Therefore when we put them in constrained environments and remove predators, the consequences are they become a little more like couch potatoes."

Up next, an entirely different kind of food problem. Recycling paper and plastic, as you know, is an effective way to save money and energy. So why not recycle all the uneaten food that goes to waste? And there is an awful lot of it. Forty percent of the food in the U.S. today goes uneaten, which means Americans are throwing out the equivalent of 165 billion - with a B - billion dollars worth of food each year. But that's not all. Food waste, as it decays in landfills, also produces methane, which is a potent greenhouse gas.

Anthropologists believe early humans evolved in Africa and then moved out from there in successive waves. However, what drove their migrations has been a matter of conjecture.

One new explanation is climate change.

Anthropologist Anders Erikkson of Cambridge University in England says the first few hardy humans who left Africa might've gone earlier but couldn't. Northeastern Africa — the only route to Asia and beyond — was literally a no man's land.

To be sure, ice on the Arctic Ocean always melts in the summer. Historically, about half of it is gone by mid-September. But this year, three-fourths of the ice has melted away, setting a dramatic new benchmark.
