The closed mind can never achieve wisdom. Must protect your fragile ego mustn't you? Isn't your ego the reason you post so much from the top of your hill here?
I have never seen a leftist change their mind when it come to their politics, which is essentially their religion. Humanism, with its offshoots of socialism/communism, egalitarianism, and multiculturalism, is an extremely flawed set of beliefs if not inconsistent with both itself and reality.
Climate science has become so infected with leftist agendas that I just don't believe half of it. Poltics + science = dishonesty, it is exactly the same as creationism which is religion + science. In the case of creationism it is the outsiders who have an agenda, in climate science the insiders have an agenda. You can't get a PhD unless you agree with the consensus, you can't get funding either or you are marginalized. This has happened often in science, 377 ohms can tell you about the scientific consenus of the electromagnetic aether around 1900.
The science one can trust somewhat is so noisy that extrapolations become almost meaningless. I have seen people argue about what type of curve fitting technique applies because the signal to noise is so low and data so unreliable. The reality is that 100 year extrapolations are not hard science, they are almost wishful thinking. There are no complete and causual models, none, so that is why it is so open to the left's religious distortions.
Quoting Hawking on Earth becoming like Venus is a very bad case of appeal to authority. Hawking is simply parroting an old discredited scare, I'm shocked he would say something so stupid. I'm not shocked that you would be impressed by it.
If you plug your nose and split the difference, you come up with a 1.5C temperature increase in the next 100 years- big deal. Not worth putting Americans into poverty. I'll make a deal with the close minded left: Stop Africans from breeding like animals when they have no money, killing all the lions (we don't hear about that one much do we like polar bears, I wonder why, could it be it isn't politically convienient?), and chopping down the forests for charcoal, and I will start caring about China's greenhouse emissions. Until then...
