Gee. 99%. That's almost unanimous. I guess that means they HAVE to be right.
But before we declare the science "settled" we might want to look back at what they were thinking in the 1970's .
The Cooling World
http://sweetness-light.com/archive/newsweeks-1975-article-about-the-coming-ice-ageA survey completed last year by Dr. Murray Mitchell of the National Oceanic and Atmospheric Administration reveals a drop of half a degree in average ground temperatures in the Northern Hemisphere between 1945 and 1968. According to George Kukla of Columbia University, satellite photos indicated a sudden, large increase in Northern Hemisphere snow cover in the winter of 1971-72. And a study released last month by two NOAA scientists notes that the amount of sunshine reaching the ground in the continental U.S. diminished by 1.3% between 1964 and 1972.
Ooooooo. That sounds VERY scientific. Very official. Good science.
Meteorologists disagree about the cause and extent of the trend, as well as over its specific impact on local weather conditions. But they are almost unanimous in the view that the trend will reduce agricultural productivity for the rest of the century. If the climatic change is as profound as some of the pessimists fear, the resulting famines could be catastrophic.
Hey look! They were unanimous that the world was cooling back in 1970's, and we were all going to starve to death because of it, so they COULDN'T be wrong... right?
So what were they saying we should do about it back then?
Climatologists are pessimistic that political leaders will take any positive action to compensate for the climatic change, or even to allay its effects.
They concede that some of the more spectacular solutions proposed, such as melting the Arctic ice cap by covering it with black soot or diverting arctic rivers, might create problems far greater than those they solve.
So polluting the Artic ice cap was on their short list of solutions, and they were wringing their hands that politicians might not take their advice. Golly, it sure is a good thing we ignored that "almost unanimous" group of scientists back in the 1970's.
