Antarctica's ice collapse threatens metres of sea level rise within decades

Dady Cherry

26th May 2014

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'. more...

Strong winds keep Antarctica cold - while Australia bakes

Tim Radford

16th May 2014

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. more...

East Antarctic ice basin 'may be at risk'

Alex Kirby

8th May 2014

The East Antarctic ice sheet is thought by most scientists to be stable, reports Alex Kirby. But a German team says it has found how a large part of it could in time melt unstoppably, causing a long term 4 metre rise in global sea levels. more...

We must cool the Arctic before it's too late

Matthew Worsdale

29th April 2014

The decline of Arctic sea ice demands a response, writes Matthew Worsdale. As Arctic temperatures rise, so does the danger of huge eruptions of methane - a powerful greenhouse gas - that will tip the climate into 'hot'. The only solution is geo-engineering. more...

Arctic at its warmest for 40,000 years

Tim Radford

10th March 2014

It's long been established that Arctic Ocean sea ice is on the retreat, writes Tim Radford. But it's the pace of change that's surprising scientists: latest studies show that the ice-free period is increasing by 5 days / decade. more...

We must prevent abrupt climate change

John Nissen

8th February 2014

Weird weather from serious flooding in the UK to acute cold and drought in the USA follows from the warming Arctic and disruptions to the jet stream, writes John Nissen. We must act now to prevent sudden changes in global climate. more...
