Global Warming - Himalayan Connection Melts

US researchers announced recently that a study of Asia's brown clouds shows that they cause as much warming as greenhouse gases. According to the study, the brown haze is a mixture of light absorbing aerosols and light scattering aerosols which cause the atmosphere to warm while causing the Earth's surface to cool.

The vast brown cloud originates from the dung and kerosene burning stoves used in many parts of Asia.

Although scientists previously thought that only carbon dioxide and other, lighter greenhouse gases could travel across the Earth, they now say that these aerosol clouds are capable of going half-way round the earth in a week.

This warming is now being blamed for the melting of glaciers in the Himalayas, according to news reports released this August.



The most interesting thing about this study is that it is not news. The same story ran in August of 2002. In fact, the report came from the UN and was presented at the Earth Summit in Johannesburg on August 26,2002.

So, if the UN, and presumably the IPCC knew about the origin and nature of the melting of the Himalayan glaciers why did they report the following in 2007?

"Himalayan glaciers are receding faster than in any other part of the world. Half a billion people in the Himalaya-Hindu-Kush region and a quarter billion downstream who rely on glacial melt waters could be seriously affected.

Glaciers in these areas could, at current rates of global warming, disappear altogether by 2035, if not sooner. "


I guess the question is not why have the global warming alarmists have been spreading the hype about the Himalayan glaciers melting as a result of carbon-emission caused climate change when they have known the real cause since 2002 - the question is, why are we surprised?

I think much of the ice that has melting in the Himalayas was caused by soot that settled on the ice, which now melts with the added heat absorption lent to the surface.

Hundreds of millions to suffer from melting ice, UN warns: http://www.thenewsroom.com/details/368605?c_id=wom-bc-ar

Update: Researchers now conclude that the Himalayan glaciers are not melting but are growing. They are still blaming global warming for this effect. They just can't make up there minds about global warming.
