Chaotic Weather Due to Chinese Smog

When it became apparent that the globe stopped warming over 17 years ago, the global warming fanatics then started with the idea of "climate chaos"--blaming increased CO2 for cold winters and changes in rainfall. (See, e.g., this 2010 article from the New York Times on "weather chaos" and this Slate article from earlier this year on the polar vortex). However, some other scientists have a different explanation:
From Tiananmen Square to the Forbidden City, smog frequently shrouds China’s famous landmarks in a grey haze. 
But as well as ruining the view for tourists and posing a health risk for locals, the air pollution over Asia’s largest cities has been found to affect weather all over the world. 
A team of U.S. scientists discovered that aerosols created by humans in Asian economies impact storm formation in the U.S. and beyond.

... A team from Texas A&M University, Pacific Northwest National Laboratory, the University of California at San Diego and Nasa’s Jet Propulsion Laboratory (JPL) used detailed pollution emission data compiled by the Intergovernmental Panel on Climate Change and looked at two scenarios: one for a rate in 1850 before the Industrial era and one from 2000.
 
By comparing the results from a global climate model, the team found that aerosols impact cloud formations and mid-latitude cyclones associated with the Pacific storm track.

‘There appears to be little doubt that these particles from Asia affect storms sweeping across the Pacific and subsequently the weather patterns in North America and the rest of the world,' said Renyi Zhang, a previous researcher at Texas A&M University and employee at JPL.
 
‘The climate model is quite clear on this point. The aerosols formed by human activities from fast-growing Asian economies do impact storm formation and global air circulation downstream.

‘They tend to make storms deeper and stronger and more intense, and these storms also have more precipitation in them. We believe this is the first time that a study has provided such a global perspective.’
Whew. Glad the science is settled. Now to collect reparations from China ....
