The trend suggests about 20 years until mass deep destabilization and emission occurs. The big thing in Svalbard has been the loss of sea ice around its coasts for extended periods and a sharp rise in average annual air temperature, similar to what's been happening across the peripheral Arctic shoreline. Once 1-10m temps reach 0C, the active layer will rapidly deepen every year, leaving a lot of extra time every winter for microbial action to break down the previously trapped carbon.
