Marianne Hill, in a Clarion-Ledger article dated May 19, asks about climate change, and if it is due to human activity. Earlier, Charles Webber, in a letter of May 11 ("Climate Change isn't hot air") writes that any unbelievers of (man-made) climate change have had their heads in the sand for the past 15-20 years. Well, from the depths of the cool sand, let me ask a question: When the polar ice cap, which extended as far south as Minnesota, started retreating at the end of the last ice age 10,000 years ago, was that warming due to man? And if not, then why is the warming of the last 100 years automatically the fault of humans?
There are many scientists who are skeptical of man-made global warming, and there is far from a "consensus" as the believers would have you think. There is a strong political movement behind the whole subject, extending to the United Nations. As MIT climate scientist Richard Lindzen said in March 2007: "controlling carbon is a bureaucrat's dream. If you control carbon, you control life." That is why the Obama administration has declared war on Big Oil, coal, natural gas fracking, the Keystone pipeline, and anything involving hydrocarbons.
The "believers" were making great headway with their rhetoric and scare tactics in the mainstream media until someone hacked into the email files of the Climate Research Unit of East Anglia University in the United Kingdom, revealing that these climatologists, and like-minded scientists, distorted data to fit the desired conclusion that carbon emissions were causing global warming.
Finally, there are dire economic consequences if the believers' agenda is implemented. The Obama administration is now trying to circumvent cap and trade legislation through the EPA by calling CO2, a necessary ingredient for plant life, a pollutant.
