WaPo also admits “there is still uncertainty about exactly how sensitive the climate system is to a given increase in carbon dioxide concentrations.”
“In past addresses, talking about green jobs didn’t work, nor did talking about energy independence. The credible way to justify fighting climate change is to discuss the science, the real reason to cut carbon emissions. There is overwhelming evidence that the planet is warming. The widespread burning of fossil fuels, meanwhile, pumps heat-trapping greenhouse gases into the atmosphere every second. There is still uncertainty about exactly how sensitive the climate system is to a given increase in carbon dioxide concentrations — but not enough uncertainty to justify ignoring the risks of rising temperatures… The EPA, for example, has not yet set rules regulating the carbon emissions of major, existing sources of greenhouse gases. Using the EPA’s top-down approach, though, is not the best way to reduce carbon emissions. Mr. Obama should invite Congress to work with him on a better alternative.”
