Why cleaner air could speed global warming

....But even as industrialized and developing nations alike steadily reduce aerosol pollution -- caused primarily by burning coal -- climate scientists are beginning to understand just how much these tiny particles have helped keep the planet cool. A silent benefit of sulfates, in fact, is that they've been helpfully blocking sunlight from striking the Earth for many decades, by brightening clouds and expanding their coverage. Emerging science suggests that their under appreciated impact has been incredible.

Very interesting read.

It does make sense as to our ozone layer isn't the only thing protecting us from the products of our sun.

The lack of sulfates from volcanoes are the real cause of global warming.

Before the latest eruption the only major eruption in the last 90 years was Mount Pinatubo. (VEI 5) or above.

in the period before 1883-1912 there were 4 major eruptions
Novarupta Aleutian Range VEI-6 Jun 6, 1912
Santa Maria Central America Volcanic Arc VEI-6 Oct 24, 1902
Mount Tarawera Taupo Volcanic Zone VEI_5 Jun 10, 1886
Krakatoa Sunda Arc VEI-6 Aug 26–27 1883

This latest eruption in Iceland is going to be a one for doing major cooling because it a very high sulfate volcanic lava and the lava that is coming into contact with water from the ice its melting
This is going to put a lot of sulfates above 30,000 feet.

Its going to be a cold summer in Europe and cool over the rest of the world.

And if the winds shift over Greenland and coat the icecap there with dark ash we may be in a for a real problem.

If the Katla volcano goes up with this one anything could happen up to a new ice-age.
