On the Air: May 24, 2020

The effects of our changing climate extend from main street to the ends of the Earth. Warmer air and oceans are melting the ice cap at the north pole, for example. And a recent study says the same thing is happening in the Antarctic.

In recent decades, the West Antarctic Ice Sheet has been melting at an increasing pace. It contains about six million cubic miles of ice. But glaciers on its edge are getting smaller. Scientists have suspected that global climate change is playing a role. But natural changes in the Pacific Ocean also change the rate at which the glaciers melt.

By the late 1960s, many Americans were getting fed up with bad news about the environment. A book early in the decade warned about the dangers of pesticides. An oil spill on the coast of California killed thousands of birds and other creatures. A river in Ohio caught fire. And pictures snapped by an Apollo astronaut showed Earth as a fragile blue ball.

To inform Americans about the problems, Senator Gaylord Nelson of Wisconsin organized an “environmental sit-in.” It was held on April 22nd, 1970 — the first Earth Day. And an estimated 20 million people took part.
