Global climate change predictions
It is often said that non-scientists must rely on “expert opinion” to determine whether claims on alleged “catastrophic man-made global warming” are true. Putting aside the fact that there is no global-warming “consensus” among experts, one does not have to be a scientist, or even proficient in science, to be able to review past predictions, and then form an informed opinion regarding the accuracy of those predictions.
Suppose, for example, you regularly watch a local TV weatherman forecast the weather for your area. Would you need a degree in meteorology in order to decide for yourself how reliable, or unreliable, the weatherman’s forecasts are?
Warnings have been issued for many decades now regarding catastrophic climate change that forecasted certain trends or occurrences that we should already have witnessed. Yet such predictions have turned out to be very, very wrong. This was certainly the case with the alarmist predictions of the 1960s and ’70s that man’s activities on Earth were causing a catastrophic cooling trend that would bring on another ice age. And it is also the case with the more recent claims about catastrophic global warming.
What follows is a very brief review of these predictions compared to what actually happened.
Americans who lived through the 1960s and ’70s may remember the dire global-cooling predictions that were hyped and given great credibility by Newsweek, Time, Life, National Geographic, and numerous other mainstream media outlets. According to the man-made global-cooling theories of the time, billions of people should be dead by now owing to cooling-linked crop failures and starvation.
“If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but 11 degrees colder by the year 2000, ” claimed ecology professor Kenneth E.F. Watt at the University of California in 1970. “This is about twice what it would take to put us in an ice age.” Of course, 2000 came and went, and the world did not get 11 degrees colder. No ice age arrived, either.
