There are ominous signs that the earth's weather patterns have begun to change dramatically and that these changes may portend a drastic decline in food production - with serious political implications for just about every nation on earth.
All too familiar right? I expect the Grauniad has an article like this every other week.
However, the above article is from a newspaper from 1975, where not only did they firmly believe there was a cooling trend that would last the rest of the century (with words like "Ice Age" used in the article), but they suggest melting the ice caps by covering them with soot, in order to avoid the catastrophic effects of the cooling trend.
Now, they're suggesting we take far more drastic measures, but to avoid a warming trend? People may argue that they weren't very sure, and were only working with the data they had available, but the same can be said of scientists today. Except the data of today has been fiddled with to meet a political agenda.
