About Those Disasters Caused by Increasing CO2...

Er...not so much. Richard Lindzen, an atmospheric physicist at MIT, puts the kabosh on the notion that increasing CO2 will cause the kind of climate disasters that have been predicted for 20 years (h/t Don Surber):
Stated briefly, I will simply try to clarify what the debate over climate change is really about. It most certainly is not about whether climate is changing: it always is. It is not about whether CO2 is increasing: it clearly is. It is not about whether the increase in CO2, by itself, will lead to some warming: it should. The debate is simply over the matter of how much warming the increase in CO2 can lead to, and the connection of such warming to the innumerable claimed catastrophes. The evidence is that the increase in CO2 will lead to very little warming, and that the connection of this minimal warming (or even significant warming) to the purported catastrophes is also minimal. The arguments on which the catastrophic claims are made are extremely weak – and commonly acknowledged as such. They are sometimes overtly dishonest.
And the conclusion to his remarks:
Our recent work on the early faint sun may prove particularly important. 2.5 billion years ago, when the sun was 20% less bright (compared to the 2% change in the radiative budget associated with doubling CO2), evidence suggests that the oceans were unfrozen and the temperature was not very different from today’s. No greenhouse gas solution has worked, but a negative cloud feedback does. You now have some idea of why I think that there won’t be much warming due to CO2, and without significant global warming, it is impossible to tie catastrophes to such warming. Even with significant warming it would have been extremely difficult to make this connection.

Perhaps we should stop accepting the term, ‘skeptic.’ Skepticism implies doubts about a plausible proposition. Current global warming alarm hardly represents a plausible proposition. Twenty years of repetition and escalation of claims does not make it more plausible. Quite the contrary, the failure to improve the case over 20 years makes the case even less plausible as does the evidence from climategate and other instances of overt cheating. In the meantime, while I avoid making forecasts for tenths of a degree change in globally averaged temperature anomaly, I am quite willing to state that unprecedented climate catastrophes are not on the horizon though in several thousand years we may return to an ice age.
Climate change "science" has been all about acquiring money and power, not about real science. Al Gore has made millions off of the suckers who bought his scare theory, but those days are gone. The true believers on the left still think we're capable of destroying the Earth, but fewer and fewer rational people are falling for the hype.

Global warming as a respected theory is dead. Global warming is this year's Y2K.
