"Since water is warmer than air"
Within a news.yahoo story about an article in Science (co-authored by Natalia Shakhova ) on methane release from Siberia, one has the text:
The release of just a "small fraction of the methane held in (the) East Siberian Arctic Shelf sediments could trigger abrupt climate warming," they wrote.
The shelf has sometimes been above sea level during the earth's history. When submerged, temperatures rise by 12-17 degrees Celsius (22-31 F) since water is warmer than air. Over thousands of years, that may thaw submerged permafrost.
