Also discussed here: Slowing Climate Change by Targeting Gases Other Than Carbon Dioxide (Science Daily, Aug. 3, 2011)
Stabilizing climate change requires reducing emissions from carbon fuels alone by almost 100% and it is clear that even if the world found a way of doing this that it would not be achieved in a century or more- far too long to avoid the impacts from a changing atmosphere. The article reviewed today examines the non carbon gas emissions which have much shorter lifetimes in the atmosphere , contribute significantly to climate change and therefore represent an opportunity to reach stabilization more quickly than through CO2 emission reductions alone.
“stabilizing the warming effect of CO2 in the atmosphere would require a decrease of about 80 percent in human-caused CO2 emissions -- in part because some of the carbon dioxide emitted today will remain in the atmosphere for thousands of years”
“ In contrast, cutting all long-lived non-CO2 greenhouse gas emissions by 80 percent could diminish their climate warming effect substantially within a couple of decades”
“ lowering emissions of greenhouse gases other than carbon dioxide could lead to some rapid changes for the better."
“Without substantial changes to human behavior, emissions of the non-CO2 greenhouse gases are expected to continue to increase”
“The non-CO2 gases studied have natural sources as well as human emissions, and climate change could amplify or dampen some of those natural processes”
“"The long-term necessity of cutting carbon dioxide emissions shouldn't diminish the effectiveness of short-term action”
