Will Iceland's Volcano Boost Geoengineering?
When Mount Pinatubo erupted in 1991, I don’t think I even heard about it. But this one event depressed global temperatures by about 1 degree Fahrenheit. Given all the attention the latest volcano‘s getting, I thought the predicted effect might be comparable. Apparently not:
Cataclysmic eruptions, led by Pinatubo and
Mount Chichon in Mexico in 1982 in the 20th century, spewed so much
debris into the upper atmosphere that they cooled the planet for
months, briefly offsetting the effect of industrial heat-trapping gases.
is not like Pinatubo. So far the scale is not big enough to have a
global effect,” said Hans Olav Hygen, a climate researcher at the
Norwegian Meteorological Institute.
Still, since politics is about perceptions, not facts, it wouldn’t surprise me if the eruption gave geoengineering another boost. Your guess?
