Global Warming, Soot, Ice

November 7, 2003 - 12:00pm

Irreversible "dangerous anthropogenic interference" with the climate system may occur with global warming of one degree Celsius, a warming that is exceeded in all IPCC scenarios.  Yet the gloom-and-doom scenarios exaggerate trends of the agents that drive global warming.  I argue that global warming could be slowed and stopped via practical actions that have other benefits.  Soot is an interesting climate forcing; elimination of anthropogenic soot and restoration of snow and ice albedos to pristine values would have the double benefit of reducing global warming and raising the level of global temperature at which dangerous anthropogenic interference occurs.
