An excellent letter was printed in our newpaper today in the Letters and I think that some of its points would be good to mention here. Thus, it is partially quoted: --------- "Global warming...puzzles scientist." To hear politicians, environmentalists and major media, there is no puzzle here. Greenhouse gases, internal combustion engines, freon from air conditioners or any source of man-caused CO2 is the culprit. But wait a minute! The missing words in the above quote are "on Pluto."...Real scientists to date have found global warming on Jupiter, Saturn, and its moon Enceledas, Venus, Mars, and on Neptune's moon Triton, as well as Pluto. Have you heard Al Gore or other doom and gloomers mention these inconvenient truths?...Gore tells us there is "a consensus" that greenhouse gases, especially CO2 is [sic] the cause. ... About 40 years ago there was "a consensus" we had global cooling. Real scientists tell us the strongest greenhouse gas is H2O and, in the scheme of things, the effects of CO2 are negligible. ...The environmentalists should agree that if neighboring planets are warming, it is not caused by the flatulence of cows, Humvees or hair spray. Here's a thought, could it be caused by the sun?"
