This article contends that we are in for a period of increased volcanic activity. Dr. Joe D'Aleo, CCM, a long time friend, wrote years ago that one of the reasons for the warming of recent decades was the low level of volcanic activity. That may be coming to an end. The computer models forecasting global warming do not allow for volcanic activity.
The seeming increase in volcanic activity a reason why I believe the U.S. needs to institute a high quality volcano watch/warning program using the existing meteorological infrastructure.
