    There is also some evidence that climate change wont be as bad as previously predicted.

    Global warming less extreme than feared?

    Temperature rise is levelling off
    After Earth’s mean surface temperature climbed sharply through the 1990s, the increase has levelled off nearly completely at its 2000 level. Ocean warming also appears to have stabilised somewhat, despite the fact that CO2 emissions and other anthropogenic factors thought to contribute to global warming are still on the rise.
    •  hasn't passed peer review yet (7+ / 0-)

      I'd be highly suspicious of any paper touted in the popular press by its authors before it passes peer review.   Such results don't have a good track record of holding up.  Especially when the topic is politically charged.

      There's also the problem that if you remove the three major causes of natural fluctuations (solar, volcanic, ENSO), there is a very steady increase of 0.02C per year, even after 2000, which the cited study seems to contradict.  For example, see figure 8 in the following:

      "Global temperature evolution 1979–2010", Grant Foster and Stefan Rahmstorf

      Bottom line, it would be a major (and good) result if it held up, but major claims require major evidence, and (offhand) this seems a bit thin so far.
