    Carbon Dioxide levels soar at poles

    According to this article, from today's Observer, carbon dioxide levels at both the north and south poles are at crisis point:

    In the last two decades, carbon dioxide levels in the atmosphere have risen from 350 to 380 ppm and scientists warn that once levels reach 500, there could be irreversible consequences that would tip the planet toward disaster: glacier melts triggering devastating sea-level rises and spreading deserts across Africa and Asia.

    Scientists and campaigners are desperate for politicians to reach agreements that will prevent the 500 ppm 'tipping point' being breached in the next half-century. These new data suggest they may have a far shorter period of time in which to act.

    The news over the past 6 months has been shocking: a methane feedback loop in Siberia from melting permafrost, a decade's worth spike in CO2 levels since 2002, double the melt rate of Greenland since 2002, a spike in carbonic acid in the oceans (perhaps what has lead to an 80% decrease in krill populations!) alarming melting over Antarctica. It really seems like the tipping point has been crossed.

    Those figures certainly continue to be alarming. The only reason I can see for people ignoring climate change now, is big business.

    Big business pays for the PR industry to promote confusion on the issue, but it is big stupidity in the people themselves to fall for it.

    True, there is certainly that.
