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 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 ...

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...

IPCC: rapid emissions cuts vital to stop worst impacts of climate change

Damian Carrington / The Guardian

3rd November 2014

The IPCC's most important ever assessment of global warming warns that the world must cut its carbon emissions must be cut sharply and soon, writes Damian Carrington - and the cost is affordable. But in fact, emissions are rising at record levels, and the IPCC's strong support for unproven-at-scale CCS technology will leave many mystified. more...

Experts 'stunned' at how fast oceans are warming

Mike G / SeSmogBlog

23rd October 2014

Southern hemisphere oceans are warming at double the expected rate, a new study has found. This may explain why surface warming has slowed over the last decade - the oceans have absorbed the 'missing' heat. more...

In a warming world, food security means crop diversity

Sayed Azam-Ali

10th October 2014

The global homogenisation of food carries costs, writes Sayed Azam-Ali - notably the world's the increasing dependence on just a few 'elite crops', creating a precarious food system vulnerable to climate change. We must diversify our diets, and the crops that that feed us. more...

The Carbon Underground: reversing global warming

Ronnie Cummins / Organic Consumers Association

21st September 2014

As millions join in climate marches and other actions around the world, writes Ronnie Cummins, the 'mainstream' focus on energy is missing the 55% of emissions that come from mismanaged land and destroyed forests. The key is to replace industrial agriculture worldwide with productive, regenerative organic farming that puts carbon back in the soil. more...

The end of fossil fuels is not the end of global warming

Andrew Lockley

17th September 2014

Of course we must quit burning fossil fuels and welcome a renewable future, writes Andrew Lockley. But that's not going to stop the Earth from warming, indeed the reverse. So ... we need some tricks up our sleeve to deal with it - in a word, geoengineering. Because it will save our lives, and our planet. more...

Farm pests' global advance threatens food security

2nd September 2014

Tim Radford

Agricultural pests - viruses, bacteria, fungi, blights, mildews, rusts, beetles, nematodes, flies, mites, spiders and caterpillars - are spreading thanks to trade, travel and global warming, writes Tim Radford. The world faces a dire future of increased crop losses and growing insecurity. more...

Europe’s warming brings risk of dengue fever

Tim Radford

31st August 2014

As greenhouse gases raise temperatures in Europe, writes Tim Radford, British researchers warn that the risk is increasing of the arrival of dengue fever and other mosquito-borne killer tropical diseases. more...

Heat accumulating in the deep oceans has put global warming on pause

Richard Allan

26th August 2014

Since 2000 global surface temperatures have risen less than expected, a fact seized on by climate change 'sceptics'. But indications are that the surplus heat has been building up all along, writes Richard Allan - in deep oceans where it does not influence observable climate. Not yet, anyway. more...

Nuclear power is no answer to global warming

Ian Fairlie

10th July 2014

If we're serious about cutting CO2 emissions, there's no place for nuclear power, writes Ian Fairlie - because it's the least cost-effective way to do it. By far the best way is to improve energy efficiency. But tell the Government the truth, and it'll close you down. more...

World Bank: tackle global warming and add $2 trillion to global economy, save a million lives

Chris Rose

Beware environmental wolves in sheep's clothing!

William Laurance

9th June 2014

What do the Australian Environment Foundation, the Renewable Energy Foundation and the Global Warming Policy Foundation have in common? They are all fiercely anti-environment, writes William Laurance - and we must beware their 'eco-doublespeak'. 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...

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...

The melting Arctic, and revolutions to come

Robert & Jack Hunziker

26th April 2014

The world is facing the imminent threat of severe climate disruption from the warming Arctic, write Robert & Jack Hunziker, leading to a global crisis. But the response of the powerful is only to increase fossil fuel exploitation - and damn the consequences. more...

Warmer freshwater ecosystems emit more methane

Tim Radford

22nd March 2014

Scientists think the amount of methane emitted to the atmosphere from freshwater ecosystems will increase as the climate warms, reports Tim Radford. And that will trigger further warming. more...

Rockies flora signal warming times

Tim Radford

After the deluge - Britain's new politics of climate change

Jonathon Porritt

20th February 2014

Floods, giant waves and billions of pounds of destruction to the UK's homes, businesses and key national infrastructure could revolutionise climate politics, writes Jonathon Porritt. But no thanks to the increasingly pathetic BBC! 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...
