With regard to the pseudoscience of human activity being the cause of global warming , it is important to understand that politics are at the root of all the furore.
Geography is probably the most important subject that should be studied because it answers more questions about where humanity came from than anything else. For example, Rene, if all the ice on the planet melted the oceans would not increase in depth to render Mt Everest as a island as proposed in the FILM "Waterworld". 100 metres maximum! Simple arithmetic.
We exist in an interglacial period.

I know it's a long read, but I would urge you all to read the following.

Forget that twerp Al Gore. The documentary film The Great Global Warming Swindle, broadcast on Channel 4 in the UK on March 8, 2007, brought together skeptical scientists who disagree with the prevailing consensus regarding human-caused global warming. Among other claims, the film states that Gore has misrepresented the data in An Inconvenient Truth, and that the actual relationship between carbon dioxide and the temperature is the other way round (that is, rise in temperature preceded an increase in carbon dioxide in the ice core samples). Several of the film's claims have been disputed by scientists and scientific bodies such as John T. Houghton [63], the British Antarctic Survey [64], Eigil Friis-Christensen [5] and the Royal Society[65]. Global warming skeptic Fred Singer wrote that the documentary is "devastating" to Gore's movie: "...The Great Global Warming Swindle is based on sound science by recording the statements of real climate scientists. An Inconvenient Truth mainly records a politician."[66]
Here is a scientific statement taken from the article below.
* Water vapor makes up 95% of all greenhouse gases and has the largest impact on the planet's temperature. Water particles in the form of clouds act to reflect incoming solar heat. The effects of clouds cannot be accurately simulated by scientists attempting to predict future weather patterns and their effects on global warming.
* The total concentration of carbon dioxide in the Earth's atmosphere is just 0.054%, a very minuscule amount. Humans contribute much less than 1% of that. The documentary states that volcanoes produce significantly more CO2 per year than humans (Durkin has subsequently admitted that this claim is wrong[8]), while plants and animals produce 150 gigatons of CO2 each year. Dying leaves produce even more CO2, and that the oceans are "the biggest source of CO2 by far." Human activity produces a "mere" 6.5 gigatons of CO2 each year. The film concludes that man-made CO2 emissions therefore cannot be causing global warming.

Yes, I have read all these article and many more besides. I couldn't give a toss about global warming. It's the next volcanic winter that people should worry about.
