Volcanic eruption in Iceland might cool the atmosphere

Volcanic eruption in Iceland and voluminous clouds of volcanic ash are stranding hundreds of thousands of air travelers at airports across northern Europe. Climate scientists claim the previous eruption of Iceland's Laki volcano in 1783-84 had profound effects on climate around the globe. Volcanic ash can cool the climate with the reflection of incoming solar radiation from the troposphere by the sulfur-rich ash, which can decrease temperatures significantly for months or even years in some cases.
