Glacial Melting in Antarctica May Become Irreversible

Thwaites glacier is likely to thaw and trigger 50cm(1.6ft) sea level rise, US study suggests.

Antarctica faces a tipping point where glacial melting will accelerate and become irreversible even if global heating eases, research suggests.

A NASA-funded study found instability in the Thwaites glacier meant there would probably come a point when it was impossible to stop it flowing into the sea and triggering a 50cm sea level rise.  Other Antarctic glaciers were likely to be similarly unstable.
