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.

Antarctic glaciers are famously losing ice around the margins of the continent, writes Maria-José Viñas. But a new study from NASA shows that those losses are offset three times over by ice thickening in central Antarctica, causing sea levels to drop. However the net ice gain may run of steam in coming decades.

The last ice age came to an end following the massive release of carbon dioxide from the Southern Ocean, write Miguel Martinez-Boti and Gianluca Marino, and the signature of that event is written in planktonic shells. It's a timely reminder that the oceans contain 60 times more carbon than the atmosphere - and we want to keep it there.

Stories told by Australia's Aboriginal peoples tell of the time, over 10,000 years ago, when the last Ice Age came to an end, and sea levels rose by 120 metres, write Nick Reid & Patrick Nunn. The narratives tally with the findings of contemporary science, raising the question: what is it about Aborigines and their culture than so accurately transmitted their oral traditions across thousands of generations?

The climate change discourse rarely looks beyond 2100, writes Pete Dolack. Maybe that's because even at current levels of CO2, we are committed to thousands of years of warming and polar ice melt that will raise sea levels by at least six meters. However the implacable imperatives of capitalism mean there's little prospect of change for a long time to come.

Last time the Earth was this warm, 130,000 years ago, England's Thames Valley was home to hippos and elephants, write Emma Stone & Alex Farnsworth.

As for the ice age that's due, scientists believe it will be postponed for at least 100,000 years.

A string of events earlier this year provided a sobering snapshot of a global climate system out of whack, writes Peter Fisher.
