Can Dennis Miller read? He has been on the rightwing propaganda shows lately with a Newsweek magazine from 1975. The magazine has an article about global cooling in it. Why someone would cite 32 year old information to make a scientific argument I don't know, that is unless on has a hidden agenda. Yes at one time science did believe the earth was cooling. Here is an explanation from Wikipedia:
"As the NAS report and the article in Newsweek both indicate, scientific knowledge regarding climate change was more uncertain than it is today. At the time that Rasool and Schneider wrote their 1971 paper, climatologists had not yet recognized the significance of greenhouse gases other than water vapor and carbon dioxide, such as methane, nitrous oxide and chlorofluorocarbons [22]. Early in that decade, carbon dioxide was the only widely studied human-influenced greenhouse gas. The attention drawn to atmospheric gases in the 1970s stimulated many discoveries in future decades. As the temperature pattern changed, global cooling was of waning interest by 1979."
Twenty years ago global cooling was discredited and the science of climatology advanced.
Dennis Miller isn't dumb. He knows that in science as more information becomes available theories are refined. At one time people thought the earth was flat, the earth was the center of the universe, and that humors were responsible for illness. All these ideas gave way to better information, that is how science works. Miller using 32 year old information to try and discredit current scientific thinking is typical of conservative thought. Conservatives by definition do not like change. Unfortunately for them burying your head up your ass doesn't prevent change from happening.
