The IPCC will release its Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) on 25 September in Monaco.
Oceans and ice (the cryosphere) harbour unique and rich biodiverse ecosystems. Oceans contain about 97% of all water and cover more than 70% of the earth’s surface. Ice, snow and glaciers cover about 10% of terrestrial surface, particularly in the polar regions and in the Himalayas, but contain 70% of the planet's freshwater allowing life on land to thrive.
Oceans and the cryosphere are intensively linked with the global carbon cycle and climate change impacts in various ways, as buffers and a source of climate change.
Because oceans are a sink for about one quarter of all human-induced carbon dioxide, the marine environment is experiencing rates of acidification unprecedented in geological time scales, contributing to the mass die-off of coral ecosystems, for instance.
The glacial ice sheets are melting at an exponential speed resulting from global warming and are now the largest reason for the global sea level rise the annual rate of which was never higher than in 2018 since measurements started.
