The Watt is a unit of power not energy; you don't bother reading the rest when you see that. How can you take a calculation seriously that quotes an energy consumption of 2,200 watts ?

It is indeed quite bizarre that a lecture supposedly advocating long-term thinking would completely fail to examine the long-term history of Earth's climate. As anyone who does not live under a rock would know by now, the Earth's climate is always changing, so at any time it is always a case of either global warming (in the literal sense) or global cooling. Superior ice core sample analysis techniques developed since 1997 revealed several facts which the "CO2 paranoid" would do well to sequester: * The Earth has been warmer in the distant past than today, * The Earth has had CO2 levels over 10 times higher in the past than today, * The rate of CO2 increase has been higher in the distant past than today, * The rate of temperature increase has been higher in the distant past than today, and all without any assistance from human activity. That is the truth as best as anyone can measure it, just as global warming seemed the truth as best as anyone could measure it during the early nineties. The "best" got better and so the facts changed. Of course the fundamentalists have not moved on from there, seemingly stuck in past and choosing to believe in a scary and guilty future instead of adapting to the more precise results of later research. With these facts in mind, and remembering the only source of heat on Earth is the Sun, why would anyone assume that the greenhouse effect drives climate change or that recent increases in either temperature or CO2 were due to human activity? A true long-term thinker (or those with a suitably long term view of climate such as geologists) would immediately see that the present is totally within the long-term natural range of climate.
