As a geologist/geochemist it is my duty to step in and clarify a few things... David - the largest oil deposits are, in fact, the oil sand deposits of northern Alberta. While everyone is looking towards the Middle East and wondering whether or not the supply will be cut off, Canada's oil sands producers plan to ramp up production to 2.4 million barrels a day of sweet crude over the next 10 years. Interestingly, this is approaching what the US imports per day now from the ME. Check out the oil sands at Syncrude Canada's website:syncrude.com Maurice - re: the origin of oil. Thomas Gold aside, there are precious few out there who can credibly argue with an organic source for oils. One of the nails in the coffin of the abiotic origin proponents are "biomarkers" - molecular fossils of once-iving organisms. I used to work with Fowler, one of the people of the reference list at the link below:oiltracers.com Lastly, let's get real about global warming. In all of earth's history there have been perhaps half a dozen glacial epochs, each of them lasting perhaps 5-10 million years. If we pick a mean value of 7 million years that means that the earth has been as cool as it is now (we are in an interglacial period) for less than 50 million of the past 4,500 million years of earth history. This means that we are living in the coldest 1-2% of all climates of all times. Statistically, things should tend toward the mean, therefore it is normal that the earth should be warming. The real question is why is the earth as cold as it is now. I have no problem with cutting down greenhouse gas emissions, but don't tell me it will stop global warming. Chicken Little meets King Canute! Rant Over. Hugh
