I'm waiting for our first major sticking snowstorm (winter's supposed to be "bad" this year according to my roommate with his meteorology minor) so I can take lots of cool pics with my DSLR cam and drive around in my AWD subaru
Their argument has been that we have "global warming", which means a rise in average global temperatures due to our CO2 emissions, invariably causing worldwide chaos if we don't become good and pure human beings and abandon our way of life *so we can go back to the stone age.* (** = slight exaggeration)
Right, so he didn't change the definition... Global warming = more energy = increased entropy.
Increased deviations from normal temperature is evidence of this, which is what makes these threads amusing. The average increase in temperature is only a part of the overall picture, although an important one. What is being watched for is average increases in temperature (ie: energy in the system) and larger deviations of local weather.
Despite the list you provide, meta-reviews of papers being pushed around for the last fifteen years or so show nearly no gulf in the scientific community. What is heavily in dispute is the ramifications and predictive models that are being used.
(I'm quite against policy action right now, fwiw. Even the worst case predictive models span huge amounts of time. In this, I agree with the economists, who unfortunately really are censored for advocating moderation.)
Suppose to get snow here this weekend, which would be nice. The mountains don't even have it yet, and it's the middle of december! I want to go skiing, dammit.
Snow day here! I really don't think it's that bad right now, I'm kind of suprised they even closed schools, actually.
As for global warming, do we really need a crisis to make more efficient energy and better technology that doesn't destroy earth? Whether the science supports the concept of climate change or not, good things can come out of what the idea forces people to do, which is look at energy differently. It wouldn't be the end of the world if major cities didn't haze a haze of pollution above them. It wouldn't be the end of the world if rivers and lakes on industrial towns didn't become acidic and polluted.
