CLEAN : Humanity must rescue oceans to rescue itself, UN warns

The video discusses the rise in global mean sea level, which increased by about 15 cm during the 20th century and is now rising at more than twice that rate. Projections suggest it could reach up to 1.10 meters by 2100 if emissions are not reduced. This rise will increase the frequency of extreme sea level events, affecting low-lying coastal cities, small islands, and deltas, leading to flooding and land loss by 2050 without significant adaptation efforts.
