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.
Says a lot about the power of the Global Media and a Well Organized Plan....and naive sheeple!
See #70... it'd be a baffling situation if it DIDN'T succeed.
