knew he faced a hard fight on Capitol Hill. The Senate, who would have to ratify the controversial treaty, were far from happy with the deal. SEN.

In other words, if you allow the developing nations to have a free ride, and if you buy their argument, well. they deserve a chance to catch up as the industrialized nations have advanced, then when we're through, have we got any significant net gain? Have we reduced emissions? NARRATOR: Ironically, most climate scientists were also underwhelmed by the Kyoto treaty. TOM M.L. WIGLEY, Nat'l Center for Atmospheric Research: If everybody were to come on board with the Kyoto Protocol, then that would slow down the rate of climate change by a very, very small amount. As a best guess, we think that the concentration of carbon dioxide in the year 2100 would be about 700 parts per million, which is roughly double what it is today. If we enact and follow the Kyoto protocol, then we might reduce the buildup by a few tens of parts per million carbon dioxide. In other words, instead of doubling the amount of carbon dioxide, we might only increase it by 90 percent. NARRATOR: Computer models show that the provisions of the Kyoto treaty would not stop the rise in atmospheric concentrations. To do this means eventually going way beyond Kyoto and cutting world fossil emissions by a half or more. How could
