... As a result, this large carbon pool is highly vulnerable for carbon loss in a future warming climate. There are major needs to reconcile model and observations in assessing permafrost carbon balance and in understanding the importance of abrupt thaw of permafrost.

... reconciling model and observation difference in Artic vegetation greening and soil carbon stock change, and (2) emerging research on disturbance of permafrost soils by abrupt thaw.

... Indicating the long-term accumulation of permafrost carbon helps put carbon release through recent and future disturbance, especially related to abrupt thaw, into a broader context. The Committee suggests augmenting this finding with a statement such as: "This large soil carbon pool in the permafrost zone has accumulated over hundreds of thousands of years." Line-Specific Comments P413, Line 24 Change "145" to "146" to be consistent to 10% of 1460 GtC.
