Because they think just like you do, that global warming is a debateable issue.

Take a look at these facts:

"This summer, Texas was hit by exactly the kind of downpours and flooding expected in a greenhouse world, and Las Vegas and other cities broiled in record triple-digit temperatures. Just last week the most accurate study to date concluded that the length of heat waves in Europe has doubled, and their frequency nearly tripled, in the past century. The frequency of Atlantic hurricanes has already doubled in the last century. Snowpack whose water is crucial to both cities and farms is diminishing. It's enough to make you wish that climate change were a hoax, rather than the reality it is."

The Anarctic ice shelves are melting, Greenland's ice pack is melting at an alarming rate.

" In April 1998 a dozen people from the denial machine—including the Marshall Institute, Fred Singer's group and Exxon—met at the American Petroleum Institute's Washington headquarters. They proposed a $5 million campaign, according to a leaked eight-page memo, to convince the public that the science of global warming is riddled with controversy and uncertainty. The plan was to train up to 20 "respected climate scientists" on media—and public—outreach with the aim of "raising questions about and undercutting the 'prevailing scientific wisdom' " and, in particular, "the Kyoto treaty's scientific underpinnings" so that elected officials "will seek to prevent progress toward implementation." The plan, once exposed in the press, "was never implemented as policy," says Marshall's William O'Keefe, who was then at API."
