The State of the Cryosphere 2023 – Two Degrees is Too High report shows that all of the Earth’s frozen parts will experience irreversible damage at 2°C of global warming, with disastrous consequences for millions of people, societies, and nature. Confirming that just 2°C of global warming will trigger irreversible loss to Earth’s ice sheets, mountain glaciers and snow, sea ice, permafrost, and polar oceans, it updates the latest science and highlights the global impacts from cryosphere loss. Reviewed and supported by over 60 leading cryosphere scientists, this is the latest report in the State of the Cryosphere series, which takes the pulse of the cryosphere on an annual basis. The cryosphere is the name given to Earth’s snow and ice regions and ranges from ice sheets, glaciers, snow and permafrost to sea ice and the polar oceans – which are acidifying far more rapidly than warmer waters. The Report describes how a combination of melting polar ice sheets, vanishing glaciers, and thawing permafrost will have rapid, irreversible, and disastrous impacts worldwide.
