Lorne Gunter had a good article today about global warming at the National Post website. The article is titled “Thirty years of warmer temperatures go poof.” It contains several of the latest studies that are casting doubt on the whole theory of man made global warming. Among them:
“[I]n September, American Craig Loehle, a scientist who conducts computer modelling on global climate change, confirmed his earlier findings that the so-called Medieval Warm Period (MWP) of about 1,000 years ago did in fact exist and was even warmer than 20th-century temperatures.
“Prior to the past decade of climate hysteria and Kyoto hype, the MWP was a given in the scientific community. Several hundred studies of tree rings, lake and ocean floor sediment, ice cores and early written records of weather — even harvest totals and censuses –confirmed that the period from 800 AD to 1300 AD was unusually warm, particularly in Northern Europe.
“But in order to prove the climate scaremongers’ claim that 20th-century warming had been dangerous and unprecedented — a result of human, not natural factors — the MWP had to be made to disappear. So studies such as Michael Mann’s “hockey stick,” in which there is no MWP and global temperatures rise gradually until they jump up in the industrial age, have been adopted by the UN as proof that recent climate change necessitates a reordering of human economies and societies.
“Dr. Loehle’s work helps end this deception.”
I’m no scientist, so I won’t say for certain whether or not man made global warming is a serious threat. But given that just about every “fix” for it involves a heavy dose of socialism, loss of individual liberty and abandonment of the capitalist system that led to some of the greatest standards of living in human history, we better be darned sure about it before we start down that road.
