I know I've been wondering about this for several years. Scientists who claim it's not true have been shouted down, insulted and in general embarrassed and made to feel like idiots for bringing it up. As Michael Crichton tells it, we are being subjected to the same kind of pressure politics about global warming as were generated by the eugenics movement in the early 1900's. See:
There is a vast amount of information about this hoax that eventually led to the Nazis belief in the theory enough to sterilize and gas millions of people.
I just recently finished the book by Michael Crichton, "State of Fear", ©2004. In his usual gripping style, he tells a very graphic tale of just why there ain't no such thing as "global warming". This is the second time that I have read this book. I keep really good books and go back to them after sufficient time has elapsed that I don't really remember the characters or much of the plot. To me it's like meeting an old friend and catching up with old times. Plus the fact that you gain so much more knowledge about the book and what the author is writing about than you did the first time.
This time, I was again intrigued enough by the plausibility of the tale he told to go back and start checking the footnotes. Author's license extends to creating phony footnotes to enhance the story but in this case I have come across extensive information that the footnotes are true and verified in many prestigious scientific journals.
Following is a brief list of the ones I have made from his book and they are doozies! If you have any doubts whatsoever, reading his book with the facts in mind make an overwhelming case, in my opinion, that the general public is being bamboozled to death by totally false information. Just to state a few of the facts, here are some quotes from the footnotes in the book:
The Greenland coastal temperatures have followed the early 20th century global warming trend. Since 1940 however, coastal stations data have undergone predominantly a cooling trend. At the summit of the Greenland ice sheet the summer average temperature has decreased at the rate of 2.2 ºC per decade since the beginning of the measurements since 1987.
From Global Warming and the Greenland Ice Sheet by P. Chylek
"Natural and anthropogenic changes in atmospheric CO2 over the last 1,000 years from air in Antartica ice and firn" by D. M. Etheridge ("firn" is an archaic term for "old snow")
"Antarctic climate change and terrestrial ecosystem response" by P. T. Doran and eleven other scientists. Published in "Nature".
From 1986 to 2000 central Antarctic valleys cooled .7ºC per decade with serious ecosystem damage from cold. ¹
Both satellite data and ground stations show slight cooling over the last 20 years
Side- looking radar measurements show West Antarctic ice is increasing by 26.8 gigatons/yr. Reversing the melting trend of the last 6,000 years. ²
Antarctic peninsula has warmed several degrees while interior has cooled somewhat. Ice shelves have retreated but sea ice has increased.
During the last four interglacials, going back 420,000 years, the Earth was warmer than it is today. ³
Less Antarctic ice has melted today than occurred during the last interglacial.
Antarctic sea ice has increased since 1979.
Trend towards more sea ice may be accelerating.
The greater part of Antarctica experiences a longer sea-ice season, lasting 21 days longer than it did in 1979.
IPCC Climate Change 2001: The Scientific Basis. UK: Cambridge University Press, 2001, p 774:
"In climate research and modelling [sic], we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that the long-term prediction of future climate states is not possible".
1. 0.7ºC = approx. 1.26º Fahrenheit 2.2ºC = approx. 3.96º Fahrenheit
2. A "gigaton" is one BILLION tons
1. Occurring or formed between periods of glacial action
2. A period of comparatively warm climate between two glaciations, esp of the Pleistocene epoch
All of this material and hundreds of other scientific papers from some of the best minds in the world are being castigated, made fun of and generally put down to serve the money making agenda of "global warming". It's very hard to find evidence unless you really hunt it up with searches on the Internet. Even then you have to cross check to make sure some dodo brain isn't making it up to make a name for himself or herself.
I welcome any comments and other knowledge about the problem.
