I can only an upside to global warming(but then again the vairations are in control by nature in the long term and not by man)
i can only see major disaster if we have global cooling(Ice age is not cool(insert pun here))
an ICE AGE would do way more damage then any global warming could...so i wish those keep marching up and down like chicken little stop it. this reminds me helen celdercot and her nuclear winter thingy in the 70s and early 80s...yeesh. and now i have to deal with Al Gore and semiAutomiocip movie about global warming....arggggg. 10 years from now an ICE AGE will start and these people will duck and cover. then again look at all the activity on mars(maybe its an awakening, with sun strengthening)
