WHY DO THE LEFT EMBRACE GW CO2 THEORY?

This was the question raised by an MP (Liberal Democrat) in the UK parliamentary debate mentioned in an earlier post. No answer was given in the debate, but he has a point, because there is no doubt that those who seek a tightly managed economy and believe the state should provide for us and control us, and knows what is best for us would naturally have an affinity with a theory which provides a very powerful reason to do just that. It is therefore natural that politicians who have no scientific background may divide on this issue according to their political beliefs. In fact many who are considered to be on the right also claim to believe in the theory. My guess is that many of them do so because they believe that it is a vote-winner, though if it is proved wrong they may live to regret it.
