The fallacy is believing that carbon is a green house gas, water vapor in the air causes more warming. What about the sun...north pole migration...doesnt volcanoes cool the planet? These are some of the things I never hear the global warming crowd talking about. Answer this? Where did all the carbon come from in the past? Was it man-made or natural.
The sun's radiation doesn't change very much. About 0.2% or so in a 11 year cycle. 2009 was a record low, I think.
The north pole doesn't move very much. Only the magnetic pole.
Big vulcano eruptions are cooling the planet for a year or two, but usually not for decades.
One upon a time all the carbon has been in the air as CO2. Then the plants appeared on earth and split up the CO2.
Dead plants and microbes got buried in the ground and created oil and coal.
