The Heat Is On - Pulitzer Prize-winning journalist Ross Gelbspan, author of The Heat Is On: The High Stakes Battle Over Earth's Threatened Climate, provides documentation on how global warming is real and increasing. He exposes the campaign by oil and coal interests, teamed with conservative politicians, to confuse the public on the issue. His book was published in 1997 as Mr. Gelspan was early in getting people to confront the facts of climate change.
