Аннотация: <jats:title>Abstract</jats:title><jats:p>Tundra and boreal ecosystems encompass the northern circumpolar permafrost region and are experiencing rapid environmental change with important implications for the global carbon (C) budget. We analysed multi-decadal time series containing 302 annual estimates of carbon dioxide (CO<jats:subПоказать полностью>2</jats:sub>) flux across 70 permafrost and non-permafrost ecosystems, and 672 estimates of summer CO<jats:sub>2</jats:sub> flux across 181 ecosystems. We find an increase in the annual CO<jats:sub>2</jats:sub> sink across non-permafrost ecosystems but not permafrost ecosystems, despite similar increases in summer uptake. Thus, recent non-growing-season CO<jats:sub>2</jats:sub> losses have substantially impacted the CO<jats:sub>2</jats:sub> balance of permafrost ecosystems. Furthermore, analysis of interannual variability reveals warmer summers amplify the C cycle (increase productivity and respiration) at putatively nitrogen-limited sites and at sites less reliant on summer precipitation for water use. Our findings suggest that water and nutrient availability will be important predictors of the C-cycle response of these ecosystems to future warming.</jats:p>
