NASA: mass gains of Antarctic ice sheet exceed losses

Maria-José Viñas / NASA

4th November 2015

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. more...

Norway's dash for Arctic oil violates its own Constitution

Aleksander Melli, Pål W. Lorentzen, Mari Seilskjær, Hans Morten Haugen &...

16th October 2015

Large-scale oil extraction in the Arctic is irreconcilable with the 2C global warming limit, write Aleksander Melli, Pål W. Lorentzen, Mari Seilskjær, Hans Morten Haugen & Truls Gulowsen. And that puts Norway's dash to develop Arctic oil into direct conflict with its Constitution, which requires the state to try and secure climate stability for its citizens, present and future. A lawsuit is imminent. more...

Victory! Shell quits Arctic

Terry Macalister / the Guardian Environment

28th September 2015

Shell's US president says the oil giant's unpopular drilling operations in Alaska's Chukchi Sea will stop for the 'foreseeable future' as exploratory drilling finds little oil and gas to justify its $7 billion investment. more...

Mammoth Arctic carbon thaw would cost us $43 trillion

Tim Radford

23rd September 2015

Something scary is lurking in the melting Arctic permafrost, write Tim Radford & Oliver Tickell: 1,700 Gt of carbon. That's 53 years worth of current emissions, and if we let it melt the impact would cost the world $43 tn. Or act now, and we could preserve the Arctic ice for a seventh as much. more...

The world is already committed to a six meter sea level rise

Pete Dolack / Systemic Disorder

24th July 2015

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. more...

Once-stable Antarctic glaciers have suddenly started melting

Bert Wouters

23rd May 2015

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? more...

Thawing Arctic carbon threatens 'runaway' global warming

Tim Radford

14th May 2015

Arctic warming is releasing ancient organic matter that's been deep-frozen for millennia, writes Tim Radford. And now scientists have discovered its fate: within weeks it's all digested by bacteria and released to the atmosphere as CO2 - with potentially catastrophic impacts on climate. more...

Shell's Arctic oil setback - unlawful use of Seattle Port

Oliver Tickell

5th May 2015

The Port of Seattle is violating its shoreline permit in allowing Shell to set up a 'home port' for its Arctic oil drilling fleet, according to Seattle officials. The finding could nix Shell's oil drilling plans for the 2015 season. more...

Polar bears at risk from pollution as well as warmth

Tim Radford

24th April 2015

As if melting ice in Polar bears' Arctic habitat was not enough, Norwegian scientists have found that organic pollutants such as pesticide residues are disrupting their thyroid and endocrine systems, adding a further threat to the species' survival. more...

Antarctic warmth brings more snow, reducing sea level rise

Alex Kirby & Oliver Tickell

18th March 2015

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. more...

Save the Arctic sea ice while we still can!

John Nissen

5th March 2015

The Arctic Ocean is coming close to complete summer meltdown, writes John Nissen - indeed it could happen as soon as September, triggering a severe deterioration in climate across the northern hemisphere. With fast-rising temperatures predicted in the coming decade, we must act now to save the Arctic, before it's too late. more...

Coming soon: the 'Big Heat'

Nafeez Ahmed

3rd March 2015

Global warming has been on vacation for a few years, writes Nafeez Ahmed. But that's only because the excess heat - two Hiroshima bombs-worth every second - has been buried in the deep ocean. But within a few years that's set to change, producing a huge decade-long warming surge, focused on the Arctic, that could overwhelm us all. 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 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...
