On Greenhouse Gases

a) 99% of greenhouse gases are non-man-made.............b) Water vapor comprises 95% of all greenhouse gases.............c) Man creates only .001% of all water vapor.............d) The other 5% of greenhouse gases is comprised of carbon dioxide (which man contributes only .117%), methane (which man contributes only .066%), and nitrogen (which man contributes only .047%).............e) Only the first 200 or so parts per million of CO2 actually has a warming effect. There is only a warming effect after that if there isn't sufficient vegetation.............f) Global warming creates CO2 (more so than the opposite). As temperatures increase naturally, CO2 from the water evaporates and infiltrates the air.............g) Underwater volcanoes (as many as several million of them) are responsible for a much larger percentage of greenhouse gases than man.............h) There have been time-frames when the CO2 levels were 25 times higher than today and there was no greenhouse effect. There have even been times of glaciation when it was higher.............i) There is a much more reliable correlation between sunspot cycle length and temperature than there is between temperature and CO2 levels.............Sources; Ian Plimer (University of Melbourne, winner of the Clarke Medal), Richard Lindzen (M.I.T., winner of the American Meteorology Society's Meisenger and Charney awards), and  David Evans (former consultant for the Australian Greenhouse Office, PhD in electrical engineering from Stanford).
