The total collapse of glaciers in West Antarctica is 'inevitable', writes Tim Radford, as the southern hemisphere gets warmer and glaciers are undermined by seawater. The news has emerged from a new analysis of satellite data.

Greenland's glaciers are more vulnerable to global warming than had previously been feared, reports Tim Radford, as ice bodies are undercut by seawater. The threat of rapidly rising sea levels just went up yet another notch.

Scientists know that if Antarctica's ice sheets and glaciers collapse, sea levels could rise 5 metres. But the idea that it will take 200 years to happen is based on a linear model, writes Dady Cherry. In fact, the process is exponential - and could take place 'within decades'.

As temperatures rise in the Southern Ocean, warmer currents are eroding the Antarctic ice sheet from below, writes Tim Radford - causing the melting rate to treble in two decades to 83 billion tonnes a year.

A new study has found that the NE section of the Greenland ice sheet - thought to be stable due to the extreme cold - has been losing ice since 2006 with increasing speed. And as Shfaqat Abbas Khan reports, that has huge implications for global sea level rise.

A study of 120 ice sheet collapses shows that 68% went from initial change to maximum retreat within 400 years - and that once triggered, the process and the associated sea level rise kept accelerating for hundreds of years. We may face a 1m sea level rise by 2100, writes Eelco Rohling - and much more in centuries to come.

Rising greenhouse gas levels are causing stronger winds over the Southern Ocean. It's good news for Antarctica, writes Tim Radford, as the circumpolar winds are keeping its ice caps cold. But Australia is getting hotter and drier - and its problems will only increase.

The Earth is on an unavoidable path towards a 1.5°C temperature rise by mid-century, says a new World Bank report. And as Alex Kirby reports, it could reach 4°C by 2100 unless immediate action is taken - with dire impacts on the planet's poorest people.
