The paper postulates that Asian emissions have a greater effect on climate change in the US than US emissions do. It would seem that the EPA’s efforts to regulate carbon in the country would be rendered moot by the NCAR report.

The climate along the Pacific coast of the US is affected by air and ocean current circulation way more than Asian carbon. That’s why temperatures along the coasts of western states remain relatively stable - cooler in summer and warmer in winter than most places in the contiguous US.
Now, after doing all the numbers in terms of atmospheric volume versus greenhouse gasses, the actual impact of Asian, as well as US emissions, do very little to affect the climate. Urban Heat Islands and solar activity have far more effect on the environment.
It seems to us that the efforts by the paper’s authors, even though it short-circuits the measures taken in the US by the EPA, is just another attempt at “proving” Anthropogenic Global Warming is reality. We’re still saying that AGW is bullsh*t.
