The global warming science facts can often be so brutal for the climate-doomsday-from-CO2 alarmists >>> the National Center for Atmospheric Research (NCAR) has determined that Asian pollution will warm the globe so much that it offsets any U.S. CO2 emission reductions

Read here. China and other Asian countries produce a lot of black carbon (soot) and other pollutants that are belched into the atmosphere in prodigious quantities. The scientists at NCAR utilized their global climate models to analyze the impact of all that filth on global temps.
The impact of these pollutants will be quite high: a +0.4°C increase of summer temps over the entire U.S. This warming happens regardless of any U.S. reductions in CO2 emissions. And to drive home this point, climate models indicate that if the U.S. were to reduce its emissions by 80% the impact on U.S. temps would be a measly 0.075°C reduction - the Asian pollutant warming overwhelms the reduction due to less CO2.
"Comparing the amount of warming in the U.S. saved by reducing our greenhouse gas emissions by some 80% to the amount of warming added in the U.S. by increases in Asian black carbon (soot) aerosol emissions (at least according to Teng et al.) and there is no clear winner. Which points out the anemic effect that U.S. greenhouse gas reductions will have on the climate of the U.S. and just how easily the whims of foreign nations, not to mention Mother Nature, can completely offset any climate changes induced by our greenhouse gas emissions reductions."
The global warming science facts conclusions: Any attempt by the U.S. to massively reduce its CO2 emissions will be a total waste of money and effort as Asian pollution will easily offset that attempt. This NCAR analysis is eye-opening and should be seriously considered by America's policymakers. But it should be remembered that this analysis is based on global climate models, which have been incredibly ineffectual at predicting temperatures, let alone climate conditions across the world or in specific regions. And it should be pointed out that U.S. temperatures over the last 15 years have been on a cooling trend of minus 2 degrees (F) per century through April 2012 - for some reason, all those past Asian pollutants have not warmed the U.S.
