Is our current climate too hot, too cold, or just right?
[I]n the pre-IPCC era, climatologists (such as Professor Lamb) simply took it for granted that the present temperature is well below the optimal point. This can easily be seen in the names they assigned to past periods warmer than the present — such as the Medieval Climate Optimum and the Holocene Climate Optimum. Had they considered this a serious question for debate, it would have been easy to choose a neutral name.We can easily see the reasoning behind “Optimum” by looking at a more recent historical precursor to the AGW movement: the embarrassing false step of the global-cooling movement. We have always been at war with Eastasia. However, Time magazine has performed the decidedly anti-Orwellian act of making its entire 20th-century archive free, and apparently unexpurgated, on line. So you can click here, and see what Time said when we were at war with Oceania.
One of the things you’ll notice is that much, much less effort is required to conjure disasters due to global cooling, than disasters due to global warming. Crop failures and starvation don’t involve a long chain of fanciful inference.
That 1974 Time article, Another Ice Age?, reads like it was written yesterday — with a few points inverted:
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.
