Effects of Climate Change on 1.5° Temperature Rise Relevant to the Pacific Islands

Warming exceeding 1.5°C is expected to greatly increase the probability of reaching critical tipping points for the Greenland and Antarctic ice sheets, with the former facing irreversible decline most likely around 1.6°C of warming. This would lead to multi-metre SLR for centuries and millennia ahead. This is consistent with recent projections of SLR which illustrate that above 2 ̊C of warming the impacts of Antarctic ice melt become increasingly apparent by the end of the current century.
