Message from the Cryosphere:
2°C will result in extensive, potentially rapid, irreversible sea-level rise from ice sheets.
2°C will result in extensive, long-term, essentially irreversible ice loss from many glaciers
2°C is far too high to prevent extensive sea ice loss at both poles, with severe feedbacks to global weather and climate.
2°C is too high to prevent extensive permafrost thaw
2°C will result in year-round, essentially permanent ocean acidification
