Soot from China, Asia, Escapes into Global Air

It is finally being recognized that soot plays a larger role in climate and the melting of polar ice than does CO2 and other conventional greenhouse gases. Besides this indirect role of causing melting snow and ice, soot may also play a more direct role in "climate change":
The report concludes that the atmospheric warming effect of black carbon pollution is as much as three to four times the consensus estimate released last year in a report by the U.N.-sponsored Intergovernmental Panel on Climate Change.

The findings are of concern to areas such as the Indian subcontinent, where retreating glaciers in the Himalayas have the potential to flood densely populated areas and affect the drinking water of billions of people.__LAT
China is likely the world's largest emitter of soot, by far, given its huge dependence upon dirty coal power plants. China has become so polluted, in fact, that Olympic athletes have traveled outside of mainland China to train for the summer games.

As can be seen from numerous satellite images, the soot emissions of China and Asia do not all stay close to the sources of blight. In fact, Canada and the US suffer from wind-blown soot from Asia. Certainly the northern sea ice has suffered from contact with Asian soot.

The IPCC GCM's are in urgent need of modification to address new findings in the area of soot contributions, ocean oscillations, cloud feedbacks, solar cycles, and other important contributions to climate change which have hitherto been ignored by the climate orthodoxy.

Don't forget volcanic dust and wind swept dust from deserts affecting large portions of the globe. They are negative forcings like your cloud formation example though.

True. Which means that they are additional drivers that are being left out of climate models.

If the IPCC GCMs are leaving out large numbers of significant climatic drivers, where do they get their credibility? From Al Gore and the Nobel Peace Prize Committee?
