Antarctica: warming ocean trebles glacial melt

Tim Radford

17th December 2014

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 cubic billion tonnes a year. more...

The melting Arctic - John Nissen's emergency call to action

Tomás d'Ornellas

15th December 2015

The Earth faces an imminent crisis caused by runaway Arctic warming. So says climate campaigner John Nissen, who travelled to COP20 in Lima to impress the dangers on delegates - and urge them to emergency action to cool the Arctic before it's too late. Tomás d'Ornellas, editor of Tecnews.pe, met him there ...

With melting Arctic ice, Canada's polar bears face wipe-out by 2100

Tim Radford

6th December 2014

The expected melting of sea ice in Canada's Arctic Archipelago will progressively render huge areas unable to support viable polar bears populations, writes Tim Radford. By 2100 the polar bears could be pushed out altogether. more...

Antarctic sea ice expands to record extent - and it's deeper than we thought

Edward Hanna

28th November 2014

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. more...

Global warming - you must be joking! How melting Arctic ice is driving harsh winters

Nick Breeze

21st November 2014

The very least 'global warming' could do for us is to give us warmer winters, right? Wrong, writes Nick Breeze, who met climate scientist and meteorologist Jennifer Francis in his attempt to understand the complex interactions of jet stream, polar vortex, the melting Arctic, and the extreme snowfall that's hitting the northeast US right now. more...

Arctic chill, red hot politics - as the ice melts, a new Cold War can still be avoided

Conn Hallinan

25th November 2014

As the Arctic ice retreats, a fragile but resource-rich landscape replete with oil, minerals, fish and islands is opening up, writes Conn Hallinan. A new land-rush is on, and it could all lead to war. But it can be avoided provided states respect the rule of law and build on existing regimes of cooperation to protect the precious Arctic environment. more...

Arctic ice loss sends Alaskan temperatures soaring

Alex Kirby

22nd October 2014

Scientists analysing more than three decades of weather data for the northern Alaska outpost of Barrow have recorded an astonishing 7°C temperature rise, writes Alex Kirby - and the likely cause is the decline in Arctic sea ice. more...

Greenpeace victory - LEGO ends Shell promotion link

The Ecologist

9th October 2014

Following a 1 million signature Greenpeace petition, LEGO has pledged not to renew a 50-year link with the oil company Shell. The move comes as Shell bids to renew its Arctic drilling in 2015, and following revelations that it is trying to dilute environmental regulation in Arctic waters. more...

Arctic madness: oil majors plead for lower safety standards

Mike G / DeSmogBlog

6th October 2014

Oil majors are gearing up to exploit Arctic oil, writes Mike G. But they don't want to carry the costs of all the safety equipment the US Government is demanding to protect the fragile Arctic environment from spills. And they're reluctant to give up the use of toxic chemical dispersants. more...

Russia: officials block indigenous leaders from UN Assembly

The Ecologist

26th September 2014

Why so few Russian representatives at the UN's World Conference on Indigenous Peoples? Officials prevented activists - some opposing Arctic oil development - from leaving the country, damaging passports and detaining them so they missed their planes. more...

Abounding life! 4,000 microbes thrive in Antarctic lake beneath the ice

Helen Thompson

15th September 2014

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? more...

Global support for a sanctuary to protect the Arctic

The Ecologist

4th September 2014

International polling today revealed strong public support for a formally protected area in the High Arctic for mammals and other marine life. The weakest support came from Japan, where opinion was evenly split over the industrialization of the Arctic. more...

Lead pollution beat Amundsen and Scott to the South Pole - and it's still pouring down today

Joe McConnell

2nd August 2014

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. more...

Australia's drought - yes, it's climate change

Tim Radford

18th July 2014

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. more...

Whalers' log books confirm - Arctic sea ice is retreating

Tim Radford

9th July 2014

Log books from British whaling ships more than 200 years ago have given new insights into the history of the Arctic sea ice, reports Tim Radford. A new study reveals that the scale of ice melt in the Arctic over the last few decades is new and unprecedented. more...

Florida's collapse will set in within a 30-year mortgage cycle

Harold R. Wanless

3rd June 2014

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? more...

Greenland's glaciers 'more vulnerable' to rapid melting

Tim Radford

27th May 2014

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. more...

West Antarctic glaciers 'past the point of no return'

Tim Radford

23rd May 2014

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. 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...

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...
