In another (mostly environmentally whacko) forum, alot of posts appeared, bloviating about dire global warming threats, and what a wonderful movie Al Gore's "Inconvenient Truth" was, prompted my response below-----
At the risk of saying "the emperor is wearing no clothes", I humbly submit that this whole issue of "global warming" ----especially aggrevated by us humans, especially in the industrialized world, and most especially in the western democracies---is a bogus issue devoid of true scientific, peer reviewed science evidence. For reference I cite "The Politically Incorrect Guide to Global Warming and Environmentalism" by Christopher C. Horner, Regnery Publishing Inc. 2007, ISBN 978-1-59698-501-8. Some salient obsevations from this scource:
The estimated man-made contributions to Greenhouse gases: CO2-3%,Nitrous Oxide-5%, Methane-10%., the remainder being produced naturally. Fluctuations in average temperatures are more affected by activity on the sun than "greenhouse gas" presence. In addition, it wasn't more than 30 years ago that "scientists" and political pundits of the time were trumpeting dire warnings of a severe global cooling!! Historically, a medieval warm period occured from AD 1100 to 1400, a "little ice age" from 1400 to 1900, and flucuations from 1900 to present day (very warm 1930's and '40's, cooler 50's , 60's, 70's, (with the dire cooling warnings!) and warming since. All of this is affected mainly by the sun. While certainly needing to be caring of our environment, we humans are but a drop in the bucket in terms of overall environmental impact!
The political fallout from Al Gore's " Inconvenient Truth" that is beginning to occur, in terms of eventual government legislation and further control of our lives will be questioned and resisted by this small sector of mankind!!! Anyhow, that's my opinion, and you're welcome to it! Cheers, Skip
