No planet for optimists: coastal flooding may come sooner and bigger than we think

Pete Dolack

8th April 2016

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? more...

Stronger storms coming to Europe's Atlantic seaboard

Tim Radford

8th April 2016

The giant waves that hit Cornwall's coast this weekend form part of a long term trend, writes Tim Radford. Extreme weather linked to global warming is leading to more violent and more frequent storms devastating beaches, ports, infrastructure and coastal communities on Europe's exposed Atlantic coastlines. more...

Ice melt, sea level rise and superstorms: the threat of irreparable harm

Jim Hansen

24th March 2016

The term 'global warming' has a reassuring, comfortable sound, writes Jim Hansen. But paleoclimate data shows the reality could be anything but, with rapid climate oscillations, large, abrupt rises in sea level, major disruptions to ocean circulation, and massive superstorms. It may already be too late to forestall this dystopian future - but then it may not be. So let's act while we still can! more...

There's only one real climate change debate, BBC: what should we do about it?

Liz Hutchins / Friends of the Earth

22nd March 2016

After a succession of the hottest years and months ever recorded, climate is a hot topic, writes Liz Hutchins. But BBC1's 'Big Questions' climate change debate last Sunday completely missed the point. Instead of debating the only real question - how should we respond? - the BBC ran yet another repeat of the so-over 'believers versus deniers' ding-dong. Why do they still not get it? more...

Global emissions stand still as temperatures soar

Alex Kirby

18th March 2016

For the second year running CO2 emissions flatlined even as the global economy was growing at around 3%, writes Alex Kirby. But sharply rising temperatures show the need for further massive renewable energy deployment to actually bring emissions down. more...

Shocking reality of climate change kicks in - but who's listening?

James Dyke, University of Southampton

18th March 2016

Last month must go down as one of the worst ever in the annals of climate change, writes James Dyke, with parts of the Arctic 16C hotter than usual and the 'safe' warming level of 2C breached across the Northern hemisphere. But even worse is the near-total lack of reaction from business, politicians and media. more...

Science Museum must get out of bed with anti-science Big Fossil funders

Drew Pearce

2nd February 2016

Why is BP sponsoring the Science Museum's 'Late' event? It's all part of creating 'scientific consent' for fossil fuels, writes Drew Pearce, in the face of scientific certainty about climate change and the need for drastic cuts in carbon emissions. That's why we gatecrashed their latest show last week. more...

Europe's summers hottest for 2,000 years - and you ain't seen nothing yet!

Alex Kirby

29th January 2016

The last 30 years of European summers have been the hottest in thousands of years, writes Alex Kirby, and we had better start getting used to it - most of all in the Mediterranean and the Arctic, where a 1.5C global temperature rise could be amplified to 3.4C and 6C respectively. more...

Hunting in the Amazon threatens rainforest carbon

The Ecologist

27th January 2016

The over-hunting of wildlife in the Amazon has an unexpected knock-on effect: the reduced seed dispersal reduces the forest's capacity to store carbon in its biomass, increasing emissions from apparently 'intact' rainforest areas. more...

The last time Earth was this hot, Britain was a land of hippos and elephants

Emma Stone & Alex Farnsworth

22nd January 2016

Last time the Earth was this warm, 130,000 years ago, England's Thames Valley was home to hippos and elephants, write Emma Stone & Alex Farnsworth. But the closest climate analogue is actually the Miocene Climate Optimum, 11 million years ago, when CO2 levels were similar to today's. As for the ice age that's due, scientists believe it will be postponed for at least 100,000 years. more...

Greenland glaciers melt rate hits 9,500 year record

Tim Radford

9th December 2015

As Arctic Peoples at COP21 in Paris appeal for unity to halt global warming, writes Tim Radford, scientists report that Greenland's glaciers are now melting at a speed not seen since the last Ice Age almost 10,000 years ago. more...

Climate 'academics for hire' conceal fossil fuel funding

Lawrence Carter & Maeve McClenaghan / Greenpeace Energydesk

9th December 2015

Investigative reporters working for Greenpeace UK's Energydesk have uncovered a nexus of senior academics willing to accept large sums of money from fossil fuel companies to write reports and newspaper articles published under their own names and university affiliations, without declaring the funding. Lawrence Carter & Maeve McClenaghan spill the beans ... more...

COP21: Lord Monckton exposes Obama's 'secret plot' for 'totalitarian world government'

Brendan Montague & Kyla Mandel

4th December 2015

Climate change denier Lord Monckton was making waves at COP21 in Paris yesterday, write Brendan Montague & Kyla Mandel, with his claims of a 'synergy of interests' between 'malevolent scientists' and power-mad politicians intent on setting up a fascist / communist world government under the guise of a climate treaty. more...

COP21 warned on global warming's evil twin - acidifying oceans

Tony Juniper

3rd December 2015

Increased atmospheric CO2 is doing much more than warming the Earth, writes Tony Juniper - it's also acidifying oceans, something that is already having major impacts on ocean ecology in the Southern Ocean and the North Atlantic. Likely effects: more CO2 in the atmosphere, more jellyfish. more...

Global warming reduces snows that water 2 billion people

Tim Radford

24th November 2015

New research warns that rising temperatures will reduce the mountain snow in 97 major river basins worldwide, writes Tim Radford - cutting summer water supply to 2 billion people in lowland areas who depend on the meltwaters. more...

Warming world means more drought in Horn of Africa

Alex Kirby

18th October 2015

Evidence stretching back 40,000 years shows that global warming will increase drying in a region of East Africa where drought already causes humanitarian crises, writes Alex Kirby - dashing earlier hopes of increased rainfall. more...

Predators keep the oceans' carbon pump ticking

Peter Macreadie, Euan Ritchie, Graeme Hays & Trisha B Atwood

29th September 2015

By keeping marine herbivores in check, predators from sharks to crabs are essential to keep the oceanic 'carbon pump' working - with seaweed and plankton fixing atmospheric carbon and bearing it down to deep waters and sediments before getting munched. It's time to give ocean predators the protection they deserve, for climate's sake. 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 2015 Sierra Nevada snowpack is at a 500-year low

Valerie Trouet & Soumaya Belmecheri

15th September 2015

The lack of snow in California's Sierra Nevada is historically unprecedented, write Valerie Trouet & Soumaya Belmecheri. It's also seriously bad news for the state's water supplies - and may be an indicator of even worse to come in a warming world. more...

Three trillion trees live on Earth - and we need every one of them

James Dyke

3rd September 2015

Isn't three trillion trees enough to keep our planet healthy? It sounds like a lot, writes James Dyke, but they are under threat as never before, from deliberate deforestation and climate change. Many of the 1.5 billion trees we are losing a year are in the last great rainforests - key ecosystems under threat of drying out forever under our escalating double onslaught. more...

The lesson of Hurricane Katrina: the worst is yet to come

Kerry Emanuel

25th August 2015

Climate change shows its true face in extreme events, writes Kerry Emanuel: the storm surge with a 12 inch head start thanks to rising sea levels, propelled by a wind that's 20 mph faster, dropping an extra inch of rain beyond the 'normal' storm. Hurricane Katrina and Typhoon Haiyan are sending us a clear message: the world must get ready for bigger and badder, fast. more...

China's emissions 14% lower than IPCC thought

Eliza Berlage

20th August 2015

The IPCC has over-estimated China's emissions since 2000 by 14%, almost 3 gigatonnes of carbon since 2000, while its energy consumption has been 10% higher than realised, writes Eliza Berlage. The country is far more carbon-efficient than we ever knew. more...

World's glaciers melting at 'unprecedented' rate

Alex Kirby

7th August 2015

Glaciers around the world are melting on a scale without precedent in recorded history, writes Alex Kirby. Measurements of over 5,000 glaciers show that they have been retreating so fast so far this century that even if climate is stablised, the ice losses will continue for years to come. more...

The scariest part of climate change is what we don't know

Bill Laurance

4th August 2015

The 'knowns' of climate change are already plenty scary enough, writes Bill Laurance. But far more worrying are the unknowns. And in a system as complex and convoluted as the global climate system there are lots of them, creating scope for many nasty surprises to emerge. more...
