I have heard that one concern of the ozone depletions that Antarctica will melt and the world ill flood. Is this true? When will it start? Where can I get more information on this subject?

Some people think that if the climate gets 4 degrees celsius (8 to 10 degrees fahrenheit) warmer on average over the next fifty years, then a part of Antarctica known as the Ross Ice Shelf may collapse into the sea and begin to melt. Global climate warming might raise sea level by 1 or 2 meters (3-6 feet), but nobody thinks it will "flood the world". However, since most people in the world live near sea level, it could cause a lot of wet basements, to say the least. The American museum of natural history and the Environmental Defense Fund are sponsoring a traveling exhibit called "Global Warming: Understanding the Forecast", which is now in San Diego and will visit Denver, St. Louis, and Oakland before ending at the Smithsonian in Washington. If you cannot go to see the exhibit, write to the Environmental Defense Fund 257 Park Avenue South New York, NY 10010 and ask them for their global warming booklet. Also read the other questions and answers in the archive of old environmental questions having to do with global warming or climate change.

Here are some books to read:

Global Warming, by Laurence Pringle, 1990

Ask your science teacher to find this for you:

Global Warming and the Greenhouse Effect: Teacher's Guide, by Colin Hocking, 1992

The article about Antarctica melting is in the magazine "Nature", by David Sugden, p. 775, October 29, 1992

The magazine "Scientific American" has an article about what might happen to the sea level if Antarctica were to disintegrate. See the March, 1993 issue for details.
