Climate change as a weapon of mass destruction

Tom Engelhardt

1st June 2014

When we speak of WMD, we usually think of weapons - nuclear, biological, or chemical - that are delivered in a moment, writes Tom Engelhardt. But what of climate change: a WMD on a long fuse, already lit and smoking ... 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...

UKIP's climate idiocy - and future mass migration

James Dyke

27th May 2014

UKIP's election success is a victory for the climate change 'skeptics', writes James Dyke. But head-in-the-sand climate politics will only provoke more mass migration to northern countries in the future - as coastal cities flood, and tropical temperatures rise. more...

Fracking: to save the climate, the gas must remain buried

Biff Vernon

26th May 2014

The fracking industry has a blind spot the size of an elephant, Biff Vernon wrote in this Open Letter to Mark Abbott, the MD of Egdon Resources - climate change, and the huge rises in sea level it will cause. 'Only carrying out orders' is no excuse. 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...

Confronting consumption: an interview with Mohan Munasinghe

Noah M. Sachs

23rd May 2014

You can actually be better off, healthier and happier with less consumption, says Munasinghe. And it's not just rich countries that need to change, he told Noah Sachs - poor countries too must develop sustainably, or the Earth's resources will simply run out. more...

World Future Council going global with 100% renewable energy

Anne Reis

23rd May 2014

A new global campaign that advocates 100% renewable energy aims to change the political mindset and make renewable energy 'the new normal'. more...

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...

Oil companies' $1.1 trillion gamble

Paul Brown

16th May 2014

Financial experts warn investors that their money is being used by oil companies for high-risk projects, reports Paul Brown, on the assumption that oil prices will go on rising, with little or no regard for climate change. $1.1 trillion could be at risk. more...

Melting glaciers have drowned lands before, and will again

Vince Gaffney

12th May 2014

The North Sea's 'Dogger Bank' was once dry land, inhabited by people and herds of Pleistocene megafauna, writes Vince Gaffney. The long-lost world of Doggerland shows how melting glaciers drowned land at the end of the last ice age. And surely not for the last time ... more...

If this is 'responsible leadership', then I'm a fracking well

Danny Chivers

16th May 2014

Former Shell oil boss Mark Moody Stuart's ableptic, self-satisfied book on 'responsible leadership' left Danny Chivers seething. The sooner we stop caring about the opinions of the Moody-Stuarts of this world, he concludes, the sooner we're likely to improve it. 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...

Climate change: the bigger picture

Charles Eisenstein

8th May 2014

Our current approach to climate change is strengthening the ideological substructure that is devouring our planet. Charles Eisenstein urges us to tackle the problem at a fundamental level and to focus on the health of humans and natural systems. more...

UK winter floods - more to come with hotter oceans

Simon Redfern

4th May 2014

A massive citizen-powered climate simulation conclusively links the UK's winter floods to global warming, writes Simon Redfern. Over 33,000 climate models running in 'screen saver' mode show a powerful connection between hotter oceans and UK rainfall. more...

Vanishing ice through artists' eyes

Martin Spray

9th May 2014

This chronicle of over two centuries of melting Alpine and polar ice, seen through the works of contemporary artists, is at its best both powerful and provocative, writes Martin Spray. But he wonders - is art really such an effective force for environmental protection? more...

Biogas - the global green solution for health, energy, environment

John M. Hawdon

8th May 2014

Biogas digesters are a key technology for global sustainable development, writes John M. Hawdon. They simultaneously combat parasites that infect a billion people, reduce deforestation and methane emissions, and deliver vital energy to rural communities. more...

Resisting the Keystone XL is legally justified - even if we are arrested

Jeremy Brecher

2nd May 2014

Nearly 100,000 people have pledged to risk arrest if the Obama administration approves the Keystone XL pipeline. Among them is Jeremy Brecher, who believes that the real criminals are governments who betray their fiduciary duty as trustees for the public good. more...

Apple bites back at climate skeptics

Robert Hunziker

6th May 2014

Apple is moving to 100% renewable energy, worldwide, writes Robert Hunziker. But even better is CEO Tim Cook's fierce put-down to fossil-fuelled, climate skeptic shareholders: 'if you don't like it, sell!' Suddenly the politics of climate change in the US shifted ... more...

Congo rainforest 'browning' as temperatures rise

Tim Radford

30th April 2014

Scientists have found that the world's second greatest rainforest, the Congo, is losing its green, writes Tim Radford. As temperatures rise and rainfall reduces, the forest canopy is taking on a browner hue, and this could be an early signal of worse damage to come. 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...

Dynamic atolls give hope that Pacific Islands can defy sea rise

Paul Kench

25th April 2014

It is widely predicted that low-lying coral islands will drown as sea levels rise, writes Paul Kench - leaving their people as environmental refugees. But new evidence suggests that these small islands are more resilient to rising seas than we thought. more...

Green or white? Planted or painted roofs can cool buildings

Gurdane Virk

15th April 2015

As the world inexorably warms, Roger Kemp shows how we can help to keep our buildings cool with roof gardens - or just with white paint. And if enough people do it, entire cities will become more cooler, more pleasant places to be when hot weather hits ... more...

IPCC's shale gas error

Alex Kirby

14th April 2014

The latest IPCC report urges a dash for gas to allow us to reduce the burning of coal, including shale gas from fracking. But as Alex Kirby reports, their calculations appear to be based on an arithmetical flaw. more...
