At times, Gore appeared to be replaying scenes from his Oscar-winning documentary,An Inconvenient Truth.He painted a bleak picture of Earth-s future, warning that rising levels of carbon dioxide could have calamitouseffects, such as increased intensity of hurricanes, more intense droughts, and the drowning of coastal cities.
But Gore diverged from his talking points to offer his thoughts on how to deal with what he called "the mostserious [crisis] we' ve ever faced". Among his recommendations were an immediate cap on carbon dioxideemissions; by 2050, Gore said he would like to see a 90% reduction of carbon dioxide levels.
Congress appeared largely receptive to his ideas, but not everyone was soldd-to put it mildly. "We need to becareful when we talk about so-called scientific facts," said Representative Joe Barton. Barton presented historicalevidence to refute Gore-s assertion that carbon dioxide concentrations preceded temperature rises. "On this point,Mr. Vice President, you're not just off a little. You're totally wrong. "
