With all the noise on the blogosphere and the TV media (not to mention the big screen) over how man has single-handedly caused the current period of rapid warming, we seem to have forgotten that roughly 30 years earlier some of the very same science that is showing man’s devastating effect on the earth, was showing the exact opposite effect on our planet.
TIME magazine ran an article on “global cooling” on June 24th of 1974 entitled “Another Ice Age?”
Here are some selections from the article.
As they review the bizarre and unpredictable weather pattern of the past several years, a growing number of scientists are beginning to suspect that many seemingly contradictory meteorological fluctuations are actually part of a global climatic upheaval. However widely the weather varies from place to place and time to time, when meteorologists take an average of temperatures around the globe they find that the atmosphere has been growing gradually cooler for the past three decades. The trend shows no indication of reversing. Climatological Cassandras are becoming increasingly apprehensive, for the weather aberrations they are studying may be the harbinger of another ice age.
Man, too, may be somewhat responsible for the cooling trend. The University of Wisconsin’s Reid A. Bryson and other climatologists suggest that dust and other particles released into the atmosphere as a result of farming and fuel burning may be blocking more and more sunlight from reaching and heating the surface of the earth.
The earth’s current climate is something of an anomaly; in the past 700,000 years, there have been at least seven major episodes of glaciers spreading over much of the planet. Temperatures have been as high as they are now only about 5% of the time.
I don’t know about you, but given the fact that an article from 1974 reads almost exactly like an article from 2006 if you swap out “cold” for “hot” raises too many questions for me to just ‘buy into’ the current political trend of blaming man because you have to take more water breaks this summer.
