Earth warming faster than expected

Earth warming faster than expected: http://news.sciencemag.org/sciencenow/2012/03/earth-warming-faster-than-expected.html "By 2050, global average temperature could be between 1.4°C and 3°C warmer than it was just a couple of decades ago, according to a new study. That's substantially higher than estimates produced by other climate analyses, suggesting that Earth's climate could warm much more quickly than previously thought."
