Global warming's record-breaking trend continues

Alex Kirby

29th July 2015

A detailed update of key climate indicators by hundreds of scientists reveals that 2014 saw rises in temperatures, sea levels and greenhouse gases to record levels, writes Alex Kirby. 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...

Climate negotiators, please cut soot and methane - but not at the expense of CO2!

Myles Allen

6th June 2015

Climatologists have spotted an 'easy hit' to reduce global warming by cutting emissions of short lived forcing agents like soot from dirty power plants, 2-stroke engines and cooking fires, writes Miles Allen. But while we should take action on these pollutants, it must not come at the expense of holding back on cutting emissions of the big long term climate forcer: carbon dioxide. more...

Geoengineer or our tropical reefs will die, scientists warn

Tim Radford

30th May 2015

To keep the world's coral reefs alive we may have to cool tropical seas by blocking the sun's rays above them, writes Tim Radford. Even if the world reduces carbon emissions, warming already 'in the pipeline' could kill 90% of the world's coral by 2050 unless we act. more...

India's killer heatwave - a deadly warning of the world we face, without climate action

Liz Hanna

30th May 2015

As delegates prepare for the Bonn climate talks, India is being struck by extreme heat with a long-delayed monsoon season and a death toll of thousands, writes Liz Hanna. If this is an indicator of the warming world to come, it's giving us all the reasons we could possibly want to act decisively before it's too late. more...

Pope Francis endorses climate action petition to world leaders

The Ecologist

15th May 2015

The Pope has urged Catholics around the world to sign a new faith-inspired petition calling on world leaders to limit global warming to 1.5C, shortly after declaring that there is 'clear, definitive and ineluctable ethical imperative to act' on climate change. more...
Scientists had thought that Arctic rivers like the Kolyma in Siberia carry dissolved carbon from melting permafrost to the oceans. They were wrong - it's all emitted to the atmosphere as CO2. Photo: Магадан via Flickr (CC BY-NC-SA).

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...

Renewable energy alone cannot reverse global warming or make a sustainable world

Pete Dolack

25th May 2015

The renewable power boom is excellent news for people and planet, writes Pete Dolack. But let's not get carried away: much energy that claims to be 'renewable; like biomass and big hydro, is no such thing. And greening our energy is just one of many steps to a sustainable world. The greatest challenges - like tackling the monster of infinite 'growth' - all lie ahead. more...

Time to 'Get Oil Out!' from sea to shining sea

Ralph Nader & David Helvarg

4th July 2015

Faced with the double crisis of global warming and the decimation of marine wildlife, what does the Obama administration do? Open up the US's Atlantic and Arctic Ocean seafronts to oil and gas drilling, write Ralph Nader & David Helvarg. But this assault on our climate and cetaceans can be stopped, as a 'Sea Party Rebellion' prepares to fight it all the way in forthcoming Presidential elections. more...

Ocean 'dead zones' are spreading - and that spells disaster for fish

Lee Bryant

9th April 2015

Oxygen levels in our oceans are falling, writes Lee Bryant, producing growing 'dead zones' where only the hardiest organisms can survive. The causes are simple: pollution with nutrient-rich wastes, and global warming. But the only solution is to stop it happening - or wait for 1,000 years. 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...

Adventures in the Anthropocene - a journey to the heart of the planet

Robert Hunziker

2nd June 2015

Gaia Vince's remarkable book is far more than a litany of the problems of global warming and mass extinction, writes Robert Hunziker. It's also an inspiring account of how people can respond to such crises in wonderful, imaginative, creative ways, achieving seemingly impossible tasks from seeding glaciers in the Himalayas, to holding back the desert with dew. more...

Sudden global warming 55m years ago was much like today

David Bond

5th January 2014

The Earth's current warming is looking similar to what took place 55 million years ago, writes David Bond. And if it works out that way, the news is good: we may avoid a mass extinction. On the other hand, the poles will melt away completely, and it will take hundreds of thousands of years for Earth to get back to 'normal'. more...

Rapid Arctic warming is spreading south

Alex Kirby

26th December 2014

Rising temperatures in the Arctic are reaching further south to the lakes and forests of Finland, writes Alex Kirby. But the warming is not affecting summer temperatures - it's concentrated into the colder months, causing a shorter, less severe winter. more...

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...
