These are not the words of a scientist but the ravings of an extremist, defaming those who dare disagree with his very dubious hyperbolic fearmongering..
“The danger is that delay will cause tipping points to be passed, such that large climate impacts become inevitable, including the loss of all Arctic sea ice, destabilization of the West Antarctic ice sheet with disastrous sea level rise later this century” .... This is unadulterated BS. there is no ‘tipping point’ in CO2, in fact CO2 impact get diminished at higher levels; in fact, there is no scientific justification for the ‘runaway’ scenario he paints.
Yes, lets see his algorithmic adjustments to the temperature data that helps make the model fit the conclusion.
Well said, bears repeating. A doubling of CO2 would not cause a doubling of CO2 greenhouse effect.
We would all have been wiped out in ~1000 AD if Usufruct-boy's ravings about tipping points were correct.
The earth really is heating up - just like it does every 1000-1500 yrs, but AGW is a bizarre politically-motivated myth.
