"MAN'S HEAT CAUSING GW" - NEW PAPER

Here is an interesting piece which explains that much of the world's extra heat comes not from heat-trapping CO2, but from the heat produced by man. This is a novel idea, but the paper has been peer reviewed, so it deserves to be taken seriously. However it should also be pointed out that these calculations do not take into account mechanisms which lose heat from the earth such as the role of clouds.
