Recent changes to the Gulf Stream causing widespread gas hydrate destabilization. Recent changes in intermediate-depth ocean temperature associated with the Gulf Stream are rapidly destabilizing methane hydrate. The area of active hydrate destabilization covers a large margin of the arctic shelf. Increase in intermediate-depth ocean temperatures is breaking the ice shield to monster methane release. This destabilization extends along hundreds of kilometers of the Siberian margin. The Arctic is leaking methane 200 times faster than usual Number of Global Warming-Induced Craters Now Estimated at 20-30. The East Siberian Arctic Shelf (ESAS) alone holds up to 1700 Gt of methane of which 50 Gt is ready for abrupt release at any time. For comparison purposes, there is currently 5 Gt of methane in the atmosphere. An abrupt release of 50 Gt would turn ugly.

Check out the Proposal "Portable biogas plants for methane capturing and house hold waste management" in the "What initiatives, policies, and technologies can significantly reduce greenhouse gas emissions from land use change and waste?" Contest.
