Short summary
Methane hydrate may be stable at the base of the permafrost zone in sediments of the Siberian continental margin, but the sediments' depth below the sea floor precludes a fast response time (order 1-10 years) that would be required for the released methane to have a significant impact on the near-term evolution of Earth's climate. However, the Arctic could amplify anthropogenic climate change by releasing carbon on timescales of centuries or millennia.
