TS.C.2.3 The ability of natural ecosystems to provide carbon storage and sequestration is increasingly impacted by heat, wildfire, droughts, loss and degradation of vegetation from land use and other impacts . Limiting the global temperature increase to 1.5°C, compared to 2°C, could reduce projected permafrost CO, losses by 2100 by 24.2 GtC . A temperature rise of 4°C by 2100 is projected to increase global burned area 50-70% and fire frequency by approx. 30%, potentially releasing 11-200 GtC from the Arctic alone . Changes in plankton community structure and productivity are projected to reduce carbon sequestration at depth .
