Professor Chris Rapley discusses the Climate Change Act 10 years on - and warns we are not acting on a 'scale or pace' to stay beneath the crucial 2ºC of warming. In this interview with NICK BREEZE, he balances the inadequacies of climate policy with the growing willingness of many people to take action
Of all the impacts of climate change, one stands out for its inexorable menace, writes Pete Dolack: rising oceans. And it's not just for distant future generations to deal with: new scientific studies show that people alive today may face 6-9 metres of sea level rise flooding well over a million sq.km including many of the world's biggest cities. So where's the emergency response?
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.
A dramatic shift has taken place in the glaciers of the southern Antarctic peninsula, writes Bert Wouters. Six years ago these previously stable bodies suddenly stated shedding 60 cubic kilometres of ice per year into the ocean. A stark warning of further surprises to come?
Rising temperatures will result in more snow falling in Antarctica, and the build-up of ice will reduce sea level rise from other sources. But as the extra weight of ice makes Antarctica's glaciers flow faster, the continent will still be a net contributor to sea level rise.
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.
While the Arctic melts, Antarctica's ice has spread to record extents in three consecutive years, writes Edward Hanna. But is the news as good as it looks? Yes, if indications from a robot submarine that the ice is thicker than expected are supported by further evidence. It may just be that Antarctica's ice is more resilient than scientists dared to hope.
Beneath half a mile of ice scientists have uncovered the first hard evidence of a life in a subglacial lake, writes Helen Thompson. And not just life, but a complex ecosystem comprising thousands of microbial species. Could Jupiter's frozen moon Europa be hiding lakes like this?
Ice core analysis shows that lead pollution in Antarctica took off in the 1880s as mining at Broken Hill, Australia, took off. Lead residues have fallen from their late 20th century peak, writes Joe McConnell - but they are still four times higher than in pre-industrial times.
Australia's prime minister thinks climate change is 'crap' and has just abolished his country's carbon-pricing system. But scientists say that it's rising levels of CO2 that are leaving the south of the country parched and sweltering - and it's only going to get worse.
We are most certainly witnessing the onset of a rapid pulse of sea level rise, writes Harold R Wanless. And low lying areas - like southeast Florida - will be the first to know about it. So how come they're building there like there's no tomorrow?
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.
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.
Robert Swan - the first person to walk to both North and South Poles - will lead his 10th annual International Antarctic Expedition this coming March as part of his Antarctica 2041 campaign. Isabel Sepkowitz discovered what it's all about.
Climate change skeptics have seized on the tale of the 'global warming scientists' stranded in Antarctica by a summer freeze-up. But Stephan Lewandowsky says there is more to the story than meets the eye ...
It takes no more than a gentle nudge to push a man over the edge of a cliff, but it is almost impossible to haul him back before he hits the ground. Given that we show no sign of putting a stop to global warming, Peter Bunyard takes a look at what the future might hold
