Gary Cohn confirmed the US intends to withdraw from the agreement without a renegotiation, but declined to provide detailsPresident Donald Trump’s top economic adviser said at the United Nations on Monday the US has not changed its plans to withdraw from the Paris climate pact without a renegotiation favorable to Washington, a step for which there is little appetite in the international community.

For centuries, humans have championed the democratic political system. But can it facilitate the radical change needed to stop the potentially annihilating effects of climate change?Although individual action to protect the environment – consuming less, recycling more, reducing one’s carbon footprint – might be a contribution if enough people did it, the battle to minimise human-induced climate change has to be a worldwide endeavour among cooperating states. The outcome of the 2015 UN Climate Change Conference was one of the most optimistic and encouraging steps hitherto achieved in that battle – that is, until Donald Trump said he intended to withdraw the US, the biggest climate polluter in history, from the agreement. The Paris agreement and President Trump’s decision illustrate the two ends of the spectrum of effort and concern. Our planet cannot be protected from a warming atmosphere – with melting ice caps, rising sea levels, droughts, floods, famines and migrations of desperate populations – without vigorous joint effort by the world’s states.

Climate models have an even better track record than the weather models that saved lives in Texas and Florida

Chief scientist says conflicting targets at different levels of government could strangle investment and worsen power supply problemsAlan Finkel has urged the Australian government to swiftly commit to the final recommendation of his energy review, warning the longer that commitment takes, the more likely states and territories are to set up conflicting emissions reduction schemes.Speaking at the Melbourne economic forum at Victoria university on Monday, Finkel, Australia’s chief scientist, said that a failure to establish a clean energy target would create more uncertainty for investors, who would have to navigate various state policies.

The Sphinx is the closest Britain comes to having a glacier. It has disappeared just six times in the last 300 years, but this year it is almost gone. Murdo MacLeod joins snow expert Iain Cameron to study the state of Scotland’s permanent snow“It’s a very sorry sight,” says Iain Cameron. It is late August and we are standing in front of Scotland’s very own Sphinx. It never had claws, paws, nor a mysterious countenance, but if it once had they would have melted away, just as the rest is about to do. “Grim,” says Cameron with gravel in his tone. “It’s pretty much in its death throes.” Continue reading...

Secretary of state Rex Tillerson and national security adviser HR McMaster both indicated the US is open to negotiations on staying in the accordSenior Trump administration officials on Sunday signalled a further softening of America’s resolve to leave the Paris climate accord, amid signs that the issue will be discussed at the United Nations general assembly in New York this week.

As Hurricane Irma battered the Caribbean, trees aerodynamically adapted to strong winds stood firmWhen Storm Aileen ripped across the UK last week the worst of the winds brought down trees, snapped off branches and shredded leaves, made worse because the trees were in full leaf and caught the wind like a sail. Compare that with the palm trees that stood up to Hurricane Irma’s immensely stronger winds, which would have torn British trees to shreds. The palm trees simply bent over at crazy angles and then bounced back again.Related: Scaling up our response to super-hurricanes Continue reading...

A world-leading system in Sydney’s Central Park precinct helps residents reuse up to 97% of their water. But a pricing change threatens future schemesIn the basement of a Sydney housing development is the world’s largest water recycling plant in a residential building.Normal apartments put more than 90% of the water they consume back into the sewer. But thanks to the recycling plant, units in Central Park, built on the site of the old Carlton brewery close to the CBD, return just 3%. Continue reading...

Burning more coal, knowing what we know, is a deliberate act of arson. We must urgently come to grips with this fact and reconnect with nature and our communitiesCoal kills people. This isn’t even slightly scientifically controversial.

David Blackburn says we need decentralised energy sources; David Lowry on nuclear not being zero-carbon technology; plus letters from David Hayes and Fred StarrI wholeheartedly agree with much of your editorial (14 September), as the economics of new nuclear is weaker than ever at a time when renewables are coming in cheaper year on year. You point out the crisis in the funding of renewables and we could not agree more. The UK desperately needs to reboot financial support for decentralised energy in order to maximise long-term benefits for all. Councils, in particular, are calling for the restoration of feed-in tariffs and other support that has been instrumental in the creation of innovative, local, low-carbon energy schemes, Passivhaus-accredited buildings, and energy efficiency programmes for dealing with the scourge of fuel poverty.While the dramatic cost reductions in offshore wind are to be welcomed, it has to be joined with renewed support for decentralised energy projects, approval for tidal energy schemes and the resumption of support for solar and onshore wind. The government must see that the energy landscape has changed dramatically. An energy review and reboot is urgently required.

Anna Jones says that, through selling its cocoa cheaply, Africa is exporting its wealth overseas; while Sue Banford claims that the soya moratorium in the Amazon has done nothing to halt deforestationOnly the final paragraph in your article on cocoa farming causing deforestation in Ivory Coast (Forests pay price for world’s taste for cocoa, 14 September) mentioned the most fundamental thing – the farmer’s livelihood, or lack of it. The low value of his (or more likely her) crop is undoubtedly the cause of this problem. But cocoa farming could also provide the solution.Recently, I was in Ivory Coast for the African Green Revolution Forum (AGRF) in Abidjan. It united many different parties – governments, the UN’s Food and Agriculture Organisation (FAO), private sector agribusiness like Syngenta, Bayer and OCP, Rabobank and the World Bank, the Rockefeller Foundation, and Bill and Melinda Gates Foundation. They are united in one firm belief: that agriculture holds the key to unlocking Africa’s economic potential – 41 million smallholders on a fertile continent that grows every crop imaginable.

Mail on Sunday criticised by Ipso for article claiming global warming data had been exaggerated to win Paris climate change agreementClaims in the Mail on Sunday that global warming data had been exaggerated in order to secure the Paris climate change agreement have been criticised by the UK’s press regulator.The Independent Press Standards Organisation censured the newspaper for publishing a story in early February that was flawed in key aspects. The news story suggested that data from the US National Oceanic and Atmospheric Administration (NOAA), one of the world’s gold-standard sources of weather and climate research, had been treated in such a way as to suggest greater warming than had really occurred.

Conservationist and champion of Afghanistan’s people and culture and promoter of literacy in rural communitiesNancy Hatch Dupree, who has died aged 89, was an American archivist, writer and champion of Afghanistan’s culture and its people, who defied communists, fundamentalists, warlords and foreign invaders over nearly five decades in Kabul.Her most important legacy is an archive documenting some of the darkest periods of Afghan history: turbulent years of civil war and Taliban rule that many would happily have let slide into obscurity. The documents are housed in the Afghanistan Centre at Kabul University, established in 2006 and one of the city’s most impressive post-Taliban buildings, inspired by traditional architecture and a reflection of Nancy and her husband Louis Dupree’s love of Afghan culture.

Cycling can make people healthy and live longer, and cut public health costs, so why can’t it be prescribed to the nation?Imagine if a team of scientists devised a drug which massively reduced people’s chances of developing cancer or heart disease, cutting their overall likelihood of dying early by 40%. This would be front page news worldwide, a Nobel prize as good as in the post.That drug is already here, albeit administered in a slightly different way: it’s called cycling to work. One of the more puzzling political questions is why it is so rarely prescribed on a population-wide level. Continue reading...

Selective breeding gives the highest yield, but potentially at a price. It’s time to go back to our rootsIf you find the whole business of organic too tame, there’s always landrace crops, which are positively subversive. Landrace crop varieties (sometimes known as folk crops) are ancient versions of the standardised crops we rely on today. Genetically variable, these biodiverse cultivars are allowed to grow at will and to cross pollinate. Farmers collect the seeds from successful crops and these become the parents of next year’s varieties. Simple.If this sounds primitive (it is in fact Neolithic), it makes much more sense than modern agriculture, which is reliant on selective breeds that are addicted to fertilisers. The idea is that the selective breeds give the highest yield when conditions are good. This is a terrible strategy in an era of climate change when conditions are not ideal. Modern agriculture has wiped out almost all original genetic diversity. Ancient cultivars of wheat are used for straw or shoved into seed banks. Proponents of the Real Green Movement want them released into the soil. Continue reading...

The former cycling world champion and Manchester’s first walking and cycling commissioner on riding safely, favourite rides and why he won’t use StravaSo, you’re the first cycling and walking commissioner for Greater Manchester. How come?Because Andy Burnham [the mayor of Greater Manchester] phoned and asked me. I was quite taken aback, because do I have any qualifications? No. But I was taken with his enthusiasm. From the first few seconds it was pretty scary because I have been on the other side of the fence campaigning and lobbying [as British Cycling’s policy advisor] and saying what should be done, and then someone else says “go on, then” – you’re in a difficult position if you don’t want to be a hypocrite.

The case for new nuclear power stations is fatuous now offshore wind power has come down in cost so much, says Ian Hill. Yes, writes Will Taylor, but don’t forget the potential of tidal energy. Hold on a minute before rejecting nuclear, argue Tim Chittenden and Jim WatertonYour excellent editorial on the reducing cost of offshore wind power (13 September) is timely in identifying the increasingly futile case for new nuclear build. It does, however, repeat the fallacy that nuclear power “is a zero-carbon technology”. The carbon emissions involved in building such immense structures, in mining and transporting uranium, and in the transport, reprocessing and storage of waste, contribute to a considerable carbon burden. Estimates vary considerably, but studies suggest that the emissions from nuclear generation could be one-10th of those of fossil fuels, but twice those of wind power.Furthermore, the need for a continuous supply is of only limited use when consumption patterns become distorted by, for example, the increased need to charge electric vehicles overnight, as your leader identifies. What is needed now, alongside continued investment in the latest generation of renewable production, is increased investment into a wide range of storage technologies, and further research and investment into the production of renewable heat.

The race is on to prove that CO2 can be taken from the air and recycled into profitable, carbon neutral fuels. But cost and investment obstacles remainIn an industrial greenhouse about 30km from Zurich, plump aubergines and juicy cherry tomatoes are ripening to perfection. Growing Mediterranean crops in Switzerland would traditionally be energy intensive but these vegetables are very nearly carbon-neutral. The greenhouse uses waste energy from a nearby refuse plant, and carbon dioxide from the world’s first commercial direct air capture plant.
