Hi all, The methane problem in the Arctic has come to a head. There is sufficient carbon trapped in permafrost to cause a multiplication of global warming by many times (at least 40 times according to my first tentative calculation). It is critical how fast this positive feedback gets going. Significant quantities of methane are already appearing in the Arctic atmosphere.
Albert Kallio points out the methane lingers, hence the local greenhouse gas effect can be significant. Thus the build up of positive feedback on Arctic warming can grow, even before the global warming feedback gets going. If we don't solve this problem, we may never have a chance to solve the other crises which beset us. I have long advocated SRM to cool the Arctic but this could be too late to stop the methane release into the atmosphere. We are now left with the "mission impossible" to stop the methane. We need urgent brainstorming on this. For example, could the Bright Water idea be applied to the East Siberian Sea? Could CCS ideas be applied to methane, as or after its release into the atmosphere? Could the methane be "mined" in some way? Cheers, John (on holiday for another week) -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
