What You Need to Know About Climate Change

Alison Lake, David Biello Jun 12, 2006

Inhofe calls global warming the greatest hoax ever perpetrated on the American people. He may be right. The campaign to emphasize uncertainty in the science of climate change over the last decade has to rank as one of the all-time great hoaxes, right up there with smoking doesn't cause cancer and Milli Vanilli's singing talent. Mr. Brokaw's special does little to seek the truth behind that deception.

It does, however, provide a good overview of the existing science on climate change, how scientists know what they know, and what we might do about it all. All this with some stunning visuals of scientists at work, including spelunking in the melting glaciers of Patagonia and dangling from trees in the Amazon. It even provides us with the photogenic poster animal for this issue: the polar bear, which may disappear from the wild if northern sea ice stops forming in the next few decades as predicted.
