From: Assessing and projecting surface air temperature conditions required to sustain permafrost in Japan
Time sequence of areas in mountainous regions of Japan with surface air temperatures that favor the maintenance of permafrost; (1) Daisetsu Mountains, (2) Hidaka Mountains, (3) Northern Japan Alps, (4) Mt. Fuji, (5) Mt. Shiretokodake, (6) Mt. Shari, (7) Southern Japan Alps, (8) Mt. Akandake, (9) Mt. Yotei. Historical simulations (black) and future projections for the RCP2.6 (blue), RCP4.5 (green), and RCP8.5 (red) scenarios are shown. Shading indicates the minima and maxima of multi-model projections, and the thick line indicates the multi-model average
