In its decision to leave the EU, the UK is cutting itself off from one of the world's most effective systems of climate governance, write Tim Rayner & Brendan Moore. But we still have our own Climate Change Act and can lead the EU, if not as a member, at least by example - provided current and future Conservative Party leadership make their commitment clear, and implement their promises.
The UK's latest carbon budget was well-received, even by environmentalists, write Kate Scott & Marco Sakai. But that's only because they didn't look hard enough. The Paris Agreement hugely elevated ambition to achieve even a 2C temperature rise limit - and the UK's effort is nowhere near the mark.
The key study that justifies the Government's claim that fracking is a climate change 'solution' is based on serious scientific errors, writes Nick Cowern. Not only has the Government failed to correct them, but it is now delaying the publication of a new official report that would reveal the truth - that fracking is considerably worse for the world's climate than coal.
The UK government is all for fracking, writes Dr Robin Russell-Jones, but on climate grounds alone it should be banned. Evidence from the US shows that shale gas is twice as dirty as coal from a climate viewpoint due to 'fugitive emissions' of methane. That makes fracking incompatible with the UK's climate change commitments and the Paris Agreement - as the CCC may soon rule.
Slavery is a terrible thing for the world's estimated 36 million slaves, writes Kevin Bales. But it's also an environmental disaster. Many slaves are forced to work in destructive activities like clearing forests for mines, farms and plantations - making slave labour the world's third biggest 'country' in terms of CO2 emissions. It really is time to end slavery!
World leaders are meeting in New York today to sign the Paris Agreement on climate change, write Stephen Buranyi & Oliver Tickell. But the world just failed a big test of its commitment to the Paris targets by deadlocking on IMO proposals to limit emissions from international shipping.
American NGO advocating for young people's future environmental rights has won a first key legal battle in its fight to force the United States to avoid dangerous climate change by cutting its greenhouse gas emissions, writes Sophie Marjanac. If upheld on appeal in higher courts, the ruling has huge implications for us all.
World Bank President Jim Kim talks a good talk on cutting support to fossil fuels. But what the bank does, writes Victoria Seabrook, is a whole other story. Not only is the WB Group still pouring money into the sector, but its funding doubled between 2011 and 2015.
This week, the International Maritime Organisation could act to curb fast-rising emissions from shipping under the Paris Agreement, write Barry Gardiner & Richard Burden. But there are growing fears that the UK government may seek to delay and obstruct vital progress.
BP's plans to explore for oil in the deep seas of the Great Australian Bight came under fire today at the company's Annual General Meeting in London, writes Graham Readfearn. The drilling would risk the ocean's rich marine wildlife - while blowing a massive hole in Australia's COP21 emissions targets.
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?
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.
The European Union's carbon market, the EU ETS, is meant to cut pollution in a cost effective way. But a new report shows that it handed the EU's biggest emitters a €24bn bumper payout over six years. Not so much the 'polluter pays' principle but the precise opposite: people pay, and polluters profit.
The US Constitution guarantees the rights of future generations, not just current ones, writes James E. Hansen. But those rights are being betrayed, knowingly and deliberately, by governments and politicians who are standing by and allowing climate change to wreak long term havoc on the planet. Today, this legal principle is being asserted in a Federal Court in Oregon.
Not only can the US save money on its electricity by moving to a 48-state power network based on high voltage DC power lines, writes Christopher Clack. It's also the key to increasing the penetration of renewables as the lowest cost energy source, with wind and solar delivering 55% of the nation's electricity demand - and a 78% reduction in carbon emissions.
Fund managers who neglect their 'duty of care' to clients by failing to put pressure on the companies they invest in to reduce their carbon emissions and prepare for a fossil-free future could be sued for their negligence, say respected experts in law, environment and finance.
Advanced new catalysts are poised to stimulate a clean energy revolution, writes Tim Radford. An organic replacement for the precious metal platinum would allow surplus electricity to be cheaply converted into hydrogen fuel, then burnt in low cost fuel cells to propel 'green' vehicles and generate power on demand.
When Chancellor George Osborne delivers his Budget next month, we can be sure that climate and environment won't take a high priority, writes Alan Simpson. All the more reason for the Labour leadership to develop a new 'one planet' economics for the 21st century that delivers social justice and respects ecological limits.
How to reconcile the Paris Agreement's target to deliver a temperature rise 'well under 2C', with its wholly inadequate mechanisms? Easy, writes Myles Allen: Make fossil fuel producers 'take back' their carbon so as to fit within a global carbon budget. And for fossil fuel producers in the rich world, that means there is no time to lose - specially to meet a 1.5C target.
Campaigners at COP21 in Paris are calling for a new 'upstream' carbon tax to be levied on fossil fuel producers, writes Henner Weithoener, and so send a clear market signal and finance poor countries' compensation for 'loss and damage' caused by climate change.
Levels of CO2 are at their the highest in 800,000 years, writes Tim Radford, but news of a probable decline in emissions this year is providing welcome cheer at the COP21 climate summit: thanks to renewables, economic growth and falling emissions can go hand in hand.
Paris has been awash with hype about 'CO2 recycling' and 'carbon neutral' or even 'carbon negative' technologies based on burning millions of trees, writes Rachel Smolker. But the alchemical notion that waste carbon can be spun into corporate gold is hitting serious reality checks. It's time to ditch the fantasies and progress the real solutions: like caring for land, soils, forests and grasslands.
It's not just Indonesia's forests and peatlands that are burning - the Amazon is suffering almost as badly, with over 18,000 fires last month in Brazil alone, write Jos Barlow & Erika Berenguer. The future is looking hot and fiery.
There's a quick climate win for COP21 negotiators to ponder, writes Wilf Lytton - one that could convert a billion tonnes a year of CO2 into mineral form while neutralising caustic wastes like coal ash and slag. But first, industries and regulators must adopt a 'recycling' mentality to these hazardous materials, rather than the 'dump and forget' model that prevails today.
