Kevin Trenberth: Imitating a Volcano to Avert Global Warming Could Be Disastrous

Kevin Trenberth is not just another boring scientist. He is the head of climate analysis for the National Center for Atmospheric Research, and he’s also unusually outspoken on the subject of global warming. When attacked by notorious denier Fred Singer, a decade ago, he defended himself briskly. He told Congress this spring that the planet was "running a fever," irritating Al Gore haters everywhere, and this past week he published a paper arguing that attempting to reduce global warming by emulating a major earthquake, such as we saw in l991 from Mt. Pinotubo, could be disastrous. The abstract warns:

Following the eruption of Mount Pinatubo in June 1991 there was a
substantial decrease in precipitation over land and a record decrease
in runoff and river discharge into the ocean from October
1991–September 1992. The results suggest that major adverse effects,
including drought, could arise from geoengineering solutions.
