But just how shall we interpret what it is telling us ?

“A noxious cocktail of soot, smog and toxic chemicals is blotting out the sun, fouling the lungs of millions of people and altering weather patterns in large parts of Asia…The byproduct of automobiles, slash-and-burn agriculture, wood-burning stoves and coal-fired power plants, these plumes of carbon dust rise over southern Africa, the Amazon basin and North America. But they are most pronounced in Asia, where so-called atmospheric brown clouds are dramatically reducing sunlight in many Chinese cities and leading to decreased crop yields in swaths of rural India…the scientists who worked on the report said the blanket of haze might be mitigating the worst effects of greenhouse gases, by absorbing solar heat or reflecting it away from the earth…The brownish haze, sometimes more than a mile thick and clearly visible from airplanes, stretches from the Arabian Peninsula to the Yellow Sea. During the spring, it sweeps past North and South Korea and Japan. Sometimes the cloud drifts as far east as California…“We used to think of this brown cloud as a regional problem, but now we realize its impact is much greater…When we see the smog one day and not the next, it just means it’s blown somewhere else.”…” Full Slice
