That's probably so however Siberia is contributing much more. The whole of subarctic tundra is at risk for rapid melting and co2 and methane release as trapped ancient organic material decays. There are also other major, imminent issues: the uncertain liability of the ESAS clathrates, zero summer sea ice (arctic ocean heating) and jetstream abnormalities (hence more variable weather day-to-day). Anyone whom wants actual facts ought to watch Paul Beckwith out of University of Ottawa on YT for detailed updates and analysis on climate change. https://youtube.com/user/PaulHBeckwith https://youtube.com/user/PaulHBeckwith
