Antarctica's ice loss is locked in, and extra snowfall won't save it—low‑lying coastal areas elsewhere to suffer
Sea-level rise is one of the most visible signs of climate change, one that is threatening low-lying coastal communities around the world. Today, about 1 billion people live in coastal areas; about 100 million live within 1 meter (3.3 feet) of sea level, highly exposed to coastal flooding.
The future of Antarctica's ice blanket depends on the unfolding of a chain of events, and a new study shows that evidence points to a single direction
Even with very strong emission reductions, Antarctica is likely to lose more ice than to gain more ice in this century. A new model analysis compared with satellite data estimates the probability of this in a particularly low-emission scenario at 92 percent. At the same time, the risk of significantly higher contributions to sea level rise increases with very high emissions. New Brunswick (U.S.A.). The Antarctic ice sheet contains so much frozen…
