Big volcanic eruptions have had a cooling effect on Earth's climate, but the Icelandic event is too small to provide any such respite from manmade global warming, scientists said on Friday.These clowns should be happy the giant carbon footprint of all those canceled airline flights has been reduced to zero.
The benchmark cooling event of the past 20 years was in 1991, when Mount Pinatubo erupted in the Philippines.
It cooled Earth's surface by 0.5 degrees Celsius (0.9 degrees Fahrenheit) over the next year, enough to offset the impact of greenhouse gases from 1991 to 1993.
A smaller cooling episode occurred in 1980, when Mount St. Helens in the U.S. state of Washington blew its top, an event that while impressive disgorged only a tenth of the material of Pinatubo.

Probaly doesn't matter since the planet has been cooling since 1998, despite the misinginformation from the global warming hoaxers.
