Ancient 'dead seas' offer a stark warning for our own future

Richard Pancost, University of Bristol

29th January 2016

For long periods animals in ancient oceans could live only in shallow surface waters, above vast 'dead zones' inhabited only by anoxic bacteria, writes Richard Pancost. Human activity is now creating immense new dead zones, and global warming could be helping as it reduces vertical mixing of waters. Could this be the beginning of something big? more...

President Obama: Keep our oil and gas in the ground!

Earthjustice, Friends of the Earth, Greenpeace USA, Waterkeeper Alliance &...

15th January 2016

Now that the US is signed up to ambitious Paris targets to limit warming, it too must play its part in keeping fossil fuels under the ground, write leading US campaigners. So let's make an immediate start by halting all new federal oil and gas leasing on public lands pending a full climate and environmental impact study. more...

After Paris, the year of Climate Insurgency

Jeremy Brecher

13th January 2016

The Paris Agreement provides a clear mandate to limit global warming, writes Jeremy Brecher. And with governments doing nowhere near enough, it's up to ordinary citizens - through civil disobedience if needs be - to make sure the world breaks free from fossil fuels. Let's make 2016 the year of 'Climate Insurgency'! more...

Greenpeace 'peer review' climate sting's first scalp?

Brendan Montague / DeSmog.uk

6th January 2015

A leading member of the climate change-skeptic Global Warming Policy Foundation has resigned from his post in the wake of a Greenpeace investigation that exposed its phoney 'peer review' process. But he insists: 'nothing going on here!' 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...

Attack of the stinging jellyfish: the winners of ocean acidification

Jason Hall-Spencer, Plymouth University

16th December 2015

Rising levels of carbon dioxide don't just cause global warming, writes Jason Hall-Spencer. Another consequence is acidifying oceans - which promises to disrupt marine ecology around the world, killing off oysters and corals, while boosting 'nuisance species' like stinging jellyfish. more...

Carlisle floods: bring back the trees, and the beavers!

Oliver Tickell

7th December 2015

The key to reducing the risk of more floods like those in Carlisle is to realise that conventional 'flood defence' can never provide security against the ever more extreme weather events that global warming will bring. We must embrace natural solutions to holding back flood waters: more trees; and bring back the beavers! 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...

WMO: record warming rises into danger zone

Alex Kirby

28th November 2015

A climate negotiators gather in Paris for COP21, the WMO say that a combination of human and natural causes will make 2015 temperatures the hottest ever - half way to the 2C 'safety threshold'. But despite the ever falling price of solar and wind, many newly industrialising countries are insisting on coal-fired development. 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...

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...

New dams, warming waters, forest fires - Lake Baikal in peril

Bryce Stewart

17th September 2015

Longer than England, almost as deep as the Grand Canyon, Russia's Lake Baikal is one of the world's greatest aquatic wonders, writes Bryce Stewart. But it's a fragile paradise: the limpid waters are warming much faster than the global average, with as yet unknown effects on its ecology. And it faces the danger of a huge dam on its principal tributary, Mongolia's Selenga River. 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...

Arctic charade: Obama's Alaskan tour and the climate change 'puzzle'

Timothy Clark

15th September 2015

President Obama's whistlestop Alaskan tour highlighted his unique ability to believe in two completely contradictory ideas at once, writes Timothy Clark. On the one hand, the importance of climate change and the urgency of preventing dangerous warming. On the other, the importance of the Arctic's fossil energy and the urgent need to exploit it as rapidly and completely as possible. more...

Emissions cuts pledges too weak to achieve 2C 'safety limit'

Alex Kirby

3rd September 2015

Promises made by governments to cut their greenhouse emissions come nowhere near stopping global warming rising above the 2C danger level, writes Alex Kirby. And in many cases the laws and policies needed to deliver them are absent. 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...

Warming world traps bumblebees in 'climate vice'

Tim Radford

10th July 2015

As Europe and North America warm, bumblebees should be able to fly north to cooler climes, writes Tim Radford. But they're not: the bees' range is receding in the south, but staying put in the north, and scientists fear their shrinking habitat will put many species at risk of extinction. more...

California is the 'canary in the coalmine' of global drought

Maude Barlow

1st July 2015

California's drought is a harbinger of things to come around the world, writes Maude Barlow. Because of global warming, yes - but also because the Golden State is an exemplar of the 'water as property for corporate profit' neoliberal paradigm that's taking over the world. It's now essential to assert water as a Commons - to be both justly shared, and fiercely protected! more...

Cuba's warming relations with the US may undermine its agroecological city farms

Julia Wright & Emily Morris

27th June 2015

Cuba is a global exemplar of organic, agroecological farming, taking place on broad swathes of land in and around its cities, write Julia Wright & Emily Morris. These farms cover 14% of the country's agricultural land, employ 350,000 people, and produce half the country's fruit and vegetables. But can they survive exposure to US agribusiness? more...
