Glacial melting in Antarctica may become irreversible

Thwaites glacier is likely to thaw and trigger 50cm sea level rise, US study 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. Proceedings of the National Academy of Sciences journal found it was likely to succumb to instability linked to the retreat of its grounding line on the seabed that would lead to it…

Antarctic ice melting faster than ever, studies show

Rate of melt has accelerated threefold in last five years and could contribute 25cm to sea-level rises without urgent action Ice in the Antarctic is melting at a record-breaking rate and the subsequent sea rises could have catastrophic consequences for cities around the world, according to two new studies. A report led by scientists in the UK and US found the rate of melting from the Antarctic ice sheet has accelerated threefold in the last five years and is now vanishing faster than at any previously recorded time. A separate…
