EcoAlert: “Earth Needs a Major Volcanic Eruption Every 18 Months to Reduce Temperatures and Delay Icecap Melt”


A new report from the Proceedings from the National Acadmey of Sciences of the United States of America says that repairing the damage from global warming will prove extremely difficult and non-cost-effective.

Severe treatment would mean injecting "sulphur dioxode particles equivalent to a major volcanic eruption, such as that of Mt Pinatubo, every 18 months to reduce temperatures and delay ice-cap melt and sea-level rises," The Ecologist reports. Other geoengineering options include installing mirrors in space and afforestation. Geoengineering approaches are risky and raise several questions about what effects they will have on the planet, leading many scientists and policy-makers to shy away from their use.
