AGW disproves itself.
Without even coming up with an explanation for what heats the earth, the notion of a positive feedback loop of temperatures and carbon dioxide causing a “latchup” in a stable and permanent too hot climate is disproved by evidence.
AGW theory is dependent on the climate being dominated by positive feedback and that we are always near a “tipping point” away from the “delicate balance”
The oft used phrases in quotes here are based on the assumption that the behavior of the global climate is dominated by positive feedback mechanisms.
The best proof of the error of AGW is that IT HASN’T HAPPENED YET!
We know that historically CO2 levels have been as much as 10 times the current levels. If there was a CO2 tipping point that we could cross that would bake the earth like Venus then it would already happened. The fact that it didn’t happen indicates that negative feedback mechanisms are more dominant and that the Earth’s climate is regulated and kept on a pretty even keel by the negative feedback regulation.
If a 1000% increase in CO2 didn’t trigger global warming, a few percentage points change due to industrialization or whatever won’t kill us either.
The only “tipping point” that I am worried about is the one that will send us into the next ice-age. If history is any guide we are over due. All of man's recorded history has taken place in the last interglacial period. The polar bears may thrive, but an ice bound planet earth will be able to support the number of people currently inhabiting the planet.
How silly can it be to be concerned about a temperature increase that is barely within the tolerances of even satellite measurements when the EKG like geologic chart of the earth's past temperatures shows we are standing at the edge of the next precipice? The saving grace is that geologic time is measured in thousands of years so the sharp decline in temperatures will still probably take a hundred years or more. But the success of the AGW hoax still baffles me.
