- 23Antarctic ice loss now irreversible regardless of snowfall●Antarctica’s ice loss is locked in, and extra snowfall won’t save it – that’s bad news for low-lying coastal areas elsew
New analysis reported in The Conversation says Antarctica's ice loss is locked in, and increased snowfall will not offset the melting. The finding means sea levels will continue rising even under optimistic scenarios, with serious implications for low-lying coastal communities worldwide. The article argues that past hopes that natural snowfall gains could balance ice loss no longer hold, reinforcing the need for emissions cuts and coastal adaptation planning.
