I thought that claim was science - not politics.

"People normally just focus on the warming effect of CO2 (carbon
dioxide), but during the Chinese economic expansion there was a huge
increase in sulfur emissions," which have a cooling effect, explained
Robert K. Kaufmann of Boston University. He's the lead author of the
study published Monday in Proceedings of the National Academy of
Sciences.

But sulfur's cooling effect is only temporary, while the carbon
dioxide from coal burning stays in Earth's atmosphere a long time.

Chinese coal consumption doubled between 2003 and 2007, and that
caused a 26 percent increase in global coal consumption, Kaufmann
said.

Now, Chinese leaders have recognized the effects of that pollution on
their environment and their citizens' health and are installing
equipment to scrub out the sulfur particles, Kaufmann said.

Sulfur quickly drops out of the air if it is not replenished, while
carbon dioxide remains for a long time, so its warming effects are
beginning to be visible again, he noted. The plateau in temperature
growth disappeared in 2009 and 2010, when temperatures lurched upward.
