Farther west in Africa, in Congo, Brazzaville, scientists have found a remarkable peat bog - a vast expanse of decaying plant material. The discovery could tell them about the whole planet's atmospheric history. It is a rare, tropical peat bog. It's the size of Pennsylvania. The thick layer of carbon it traps may offer clues to what was in the air over 10,000 years ago. Dr. Simon Lewis of the University of Leeds led the research team, and he joins us now to tell us about this little-studied region. Welcome to the program.
I've been wondering lately, do animals invent names? As in names for themselves? Names for each other? I've always thought that what we do when we call ourselves "Ralph" or "Laura" is unique, something exclusively human. But it turns out that's wrong. Other animals have name-like calls that they use much like we do. I've posted about this before (regarding horses, dolphins and little parakeets) ...
OK. The word fracking was added to the Merriam-Webster dictionary this month. It is defined as the injection of fluid into shale beds at high pressure in order to free up petroleum resources. Despite getting this official definition, both the spelling and meaning of fracking remain controversial. Marie Cusick, from member station WITF, reports.
MARIE CUSICK, BYLINE: This is a fracking site in northeastern Pennsylvania. It's one of the most productive parts of Marcellus Shale natural gas formation.
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.
A massive peat bog the size England has been found in West Africa's Republic of Congo.
The previously undiscovered bog is thought to reach nearly 23 feet beneath the ground and contain billions of tons of peat –- ancient, partially decayed vegetation. It could cover an area 40,000 to 80,000 square miles, scientists believe in the Congo Republic, also referred to as Congo-Brazzaville.
The entire state of California is in a severe drought. Farmers and farmworkers are hurting.
You might expect this to cause food shortages and higher prices across the country. After all, California grows 95 percent of America's broccoli, 81 percent of its carrots and 99 percent of the country's artichokes, almonds and walnuts, among other foods.
Yet there's been no sign of a big price shock. What gives?
