seasons in Alaska will lengthen by 48-87 d yr1 relative to historical growing season length , and the start of growing season is expected to shift 1-4 weeks earlier . Feasible growing areas across the Arctic are expected to shift northward and increase within the 55°-69ºN region . Permafrost thaw  increases drainage, which is a potential benefit, but can also increase erosion, subsidence and irregular surfaces, inhibiting agriculture . Conversion of Arctic soils to croplands may also release carbon stored in vegetation and soils .
