Global Warming? Never Mind, the Chinese Took Care of That...

...with their dirty coal-fired power plants:

Smoke belching from Asia's rapidly growing economies is largely responsible for a halt in global warming in the decade after 1998 because of sulphur's cooling effect, even though greenhouse gas emissions soared, a U.S. study said on Monday.

The paper raised the prospect of more rapid, pent-up climate change when emerging economies eventually crack down on pollution.

World temperatures did not rise from 1998 to 2008, while manmade emissions of carbon dioxide from burning fossil fuel grew by nearly a third, various data show.

The researchers from Boston and Harvard Universities and Finland's University of Turku said pollution, and specifically sulphur emissions, from coal-fueled growth in Asia was responsible for the cooling effect.

Sulphur allows water drops or aerosols to form, creating hazy clouds which reflect sunlight back into space.

"Anthropogenic activities that warm and cool the planet largely cancel after 1998, which allows natural variables to play a more significant role," the paper said.

Natural cooling effects included a declining solar cycle after 2002, meaning the sun's output fell.

The study said that the halt in warming had fueled doubts about anthropogenic climate change, where scientists say manmade greenhouse gas emissions are heating the Earth.

"It has been unclear why global surface temperatures did not rise between 1998 and 2008," said the study published in the Proceedings of the National Academy of Sciences of the United States.

A peak in temperatures in 1998 coincided with a strong El Nino weather event, a natural shift which brings warm waters to the surface of the Pacific Ocean every few years.

Subsequent years have still included nine of the top 10 hottest years on record, while the U.N. World Meteorological Organization said 2010 was tied for the record.

The fact that global temperature haven't increased in the last ten years while CO2 has continued to increase exponentially has been a thorn in the side of the IPCC and the warming alarmists. For an amusing take down of the conclusions of this paper regarding the cause of the "thermopause", you should read Dr. David Whitehouse's comments.

Also global warming related, a new study shows that the more scientifically educated you are, the more likely you are to be a global warming "skeptic."

The conventional explanation for controversy over climate change emphasizes impediments to public understanding: Limited popular knowledge of science, the inability of ordinary citizens to assess technical information, and the resulting widespread use of unreliable cognitive heuristics to assess risk. A large survey of U.S. adults (N = 1540) found little support for this account. On the whole, the most scientifically literate and numerate subjects were slightly less likely, not more, to see climate change as a serious threat than the least scientifically literate and numerate ones.
