Human Caused Global Warming is not being researched; it is being promoted. Al Gore and his fellow investors have spent over a hundred million dollars in creating a crisis of human-caused global warming out of (quite literally) thin air. They are not doing this out of the goodness of their hearts. They expect to reap billions in profits from the trading of Carbon Credits, a "license to pollute" available for a price and subject to brokerage fees. One of the people Al Gore relied on to create this scheme was Ken Lay, late of ENRON, aka the Crooked "E". Al Gore plans to use Carbon Dioxide to do to the world what Ken Lay did to California using electricity; loot the people!
