Insincere “skeptic” shills
January 9, 2012
Interesting BBC article, on how, if it were not for our CO2 emissions, we should expect another ice age in 1500 years. It includes some discussion of how low CO2 would need to be for this to occur — one estimate is 240ppm, others are as high as 270ppm. Our current levels are 390ppm, and we passed 320ppm in 1965.
Yet the reporter manages to find (why?) people who insist that this means that our current unrestrained CO2 emissions are a good thing. These presumably are the same people who end up overdosed on medicine — because if a little is good, why not take a lot?
They also have a blinkered view of planning for the future. Once we dig/drill all the carbon and burn it, it’s out of our control. Eventually it will be reabsorbed into the oceans and other carbon sinks, and we’ll have deprived ourselves of a handy knob for warming the planet. If CO2 levels sink below the ice age threshold while we are still in a glacier-friendly part of the Milankovitch cycle, we’ll be up a frozen creek without a paddle. You can tell these guys are insincere shills, because if they really cared about preventing the next ice age, they’d be in favor of throttling emissions back to much lower (but non-zero) levels, and preserving our ability to inject CO2 into the atmosphere in the future.
