Joe Romm of Think Progress points out that, among the other things they are completely wrong about, the political opponents of climate science also think that we can go backwards by cutting carbon emissions.
This notion that we can reverse climate change by cutting emissions is one of the most commonly held myths — and one of the most dangerous, as explained in this 2007 MIT study, “Understanding Public Complacency About Climate Change: Adults’ mental models of climate change violate conservation of matter.”
…The fact is that, as RealClimate has explained, we would need “an immediate cut of around 60 to 70% globally and continued further cuts over time” merely to stabilize atmospheric concentrations of CO2 – and that would still leave us with a radiative imbalance that would lead to “an additional 0.3 to 0.8ºC warming over the 21st Century.” And that assumes no major carbon cycle feedbacks kick in, which seems highly unlikely.
We’d have to drop total global emissions to zero now and for the rest of the century just to lower concentrations enough to stop temperatures from rising. Again, even in this implausible scenario, we still aren’t talking about reversing climate change, just stopping it — or, more technically, stopping the temperature rise…
We all need to understand that it’s too late to prevent global warming, and that climate change is happening now. It’s irreversible (except over thousands of years). All we can do at this point is try to minimize the amount of warming, and develop plans to cope with the effects of climate change on our economy and way of life. But our political system thrives on myths, and the truth is still getting shouted down.
UPDATE: Rush Limbaugh is claiming contrary to basic physics that “carbon in the atmosphere may actually be making things cooler, not warmer.”
