JASON on Severe Space Weather and the Electric Grid
The U.S. electric power grid is vulnerable to damage from severe electromagnetic solar storms and remedial measures should be taken to reduce that vulnerability, a new study (large pdf) from the JASON scientific advisory panel concluded. On the other hand, the JASONs said, catastrophic worst-case scenarios advanced by some are not plausible, and they should not serve as a basis for policy making. Public disclosure of the new JASON study was blocked by the Department of Homeland Security, which sponsored the analysis. But a copy was obtained by Secrecy News. Concerns about the vulnerabilities of technical infrastructure to space weather have been growing since the sun entered the early stages of the current sunspot cycle in 2009, increasing prospects for severe solar storms, the report said. We agree that the U.S. electric grid remains vulnerable, the JASONs concluded . Mitigation should be undertaken as soon as possible to reduce the vulnerability of the U.S. grid. The cost appears m...
