The document discusses the impacts of climate change on oceans and cryosphere (ice) as outlined in the IPCC's Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). It notes that sea level rise will continue beyond 2100 and could reach 1 meter by 2300 under low emissions scenarios but up to 5.4 meters under high emissions. Adaptation will be necessary to address sea level rise impacts, with low emissions giving the best chance of successful adaptation. The document emphasizes that every fraction of a degree of warming, every year of action or inaction, and every mitigation or adaptation action matters to address the threats of climate change on oceans, coasts, and low-lying islands.
