The process of relocating people from New Orleans should start immediately, as the city has reached a “point of no return” that will see it surrounded by the ocean within decades due to the climate crisis, a stark new study has concluded. Ongoing sea-level rise and the rampant erosion of wetlands in southern Louisiana will swallow up the New Orleans area within a few generations, with the new paper estimating the city “may well be surrounded by the Gulf of Mexico before the end of this century”.

The critical Atlantic current system appears significantly more likely to collapse than previously thought after new research found that climate models predicting the biggest slowdown are the most realistic. Scientists called the new finding “very concerning” as a collapse would have catastrophic consequences for Europe, Africa and the Americas.

The world has become well versed in the importance of the strait of Hormuz to the world’s energy flows, but attention is increasingly turning to its vital role in another market – the fertiliser on which harvests depend. A third of the global trade in raw materials for fertiliser passes through the maritime choke point, which is also the route for 20% of shipments of natural gas, which is required to make it.

The world has entered an era of “global water bankruptcy” that is harming billions of people, a UN report has declared. The overuse and pollution of water must be tackled urgently, the report’s lead author said, because no one knew when the whole system could collapse, with implications for peace and social cohesion. All life depends on water but the report found many societies had long been using water faster than it could be replenished annually in rivers and soils, as well as over-exploiting or destroying long-term stores of water in aquifers and wetlands.

US demand to own Greenland leaves little scope for compromise, and forcing the issue would entail end of Nato Greenland, with a population of fewer than 57,000, might not seem to be the territory on which the future of the relationship between Europe and the US, the viability of Nato as the world’s most successful defence alliance, or even the fractured relations between the UK and Europe would be determined. But battlefields are sometimes the product of chance, rather than choice. It now feels as if Donald Trump’s threat to impose 10% tariffs on eight fellow Nato states for sending troops last week to support Greenland’s sovereignty may be one of those clarifying moments in which Europe had no option. Successive European leaders condemned Trump’s blackmail and intimidation on Sunday and they sounded as if they meant it.

Bronwen Maddox says Trump’s rejection of international law leaves UK and Europe facing huge dilemma

“Combustion is the problem – when you’re continuing to burn something, that’s not solving the problem,” says Prof Mark Jacobson. The Stanford University academic has a compelling pitch: the world can rapidly get 100% of its energy from renewable sources with, as the title of his new book says, “no miracles needed”. Wind, water and solar can provide plentiful and cheap power, he argues, ending the carbon emissions driving the climate crisis, slashing deadly air pollution and ensuring energy security. Carbon capture and storage, biofuels, new nuclear and other technologies are expensive wastes of time, he argues.

Une commission d’enquête des Nations unies a désormais confirmé ce que les organisations israéliennes, palestiniennes et internationales de défense des droits humains, ainsi que de nombreux spécialistes du génocide, affirmaient déjà : la guerre menée par Israël à Gaza équivaut à un génocide. La commission estime que les massacres, les attaques contre les infrastructures vitales, la famine, les déplacements de population et le refus de soins médicaux répondent à la définition juridique du crime le plus grave de l’histoire. Elle conclut que l’intention génocidaire est « la seule conclusion raisonnable » à tirer des déclarations des dirigeants israéliens et du comportement de leurs forces à Gaza.

Les scientifiques ont déclaré aujourd’hui que les océans de la planète sont en plus mauvaise santé qu’on ne le pensait, tout en avertissant qu’une mesure clé montre que nous « manquons de temps » pour protéger les écosystèmes marins. L’acidification des océans, souvent appelée le « jumeau maléfique » de la crise climatique, est causée par l’absorption rapide du dioxyde de carbone par les océans, où il réagit avec les molécules d’eau, entraînant une baisse du pH de l’eau de mer. Elle endommage les récifs coralliens et d’autres habitats océaniques et, dans les cas extrêmes, peut dissoudre les coquilles des créatures marines.

Mark Lynas has spent decades pushing for action on climate emissions but now says nuclear war is even greater threat Climate breakdown is usually held up as the biggest, most urgent threat humans pose to the future of the planet today.

The researchers also found the tiny particles in liver and kidney samples.

It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.

Greenpeace lost – not because it did something wrong but because it was denied a fair trial The stunning $667m verdict against Greenpeace last week is a direct attack on the climate movement, Indigenous peoples and the first amendment.

The economic damage wrought by climate change is six times worse than previously thought, with global heating set to shrink wealth at a rate consistent with the level of financial losses of a continuing permanent war, research has found.

A panel of international scientists has moved their symbolic “Doomsday Clock” closer to midnight than ever before, citing Russian nuclear threats amid its invasion of Ukraine, tensions in other world hotspots, military applications of artificial intelligence and the climate crisis as factors underlying the risks of global catastrophe.

In 1919, at the height of a global crisis that resulted from the turmoil of the Russian Revolution, the devastation of the first world war, and the collapse of Europe’s great continental empires, Irish writer William Butler Yeats penned his famed warning to humanity, mourning the end of the old world: “Things fall apart; the centre cannot hold / Mere anarchy is loosed upon the world.”

The world’s addiction to fossil fuels is a “Frankenstein’s monster sparing nothing and no one”, the UN secretary general, António Guterres, told leaders at the World Economic Forum in Davos on Wednesday. “Our fossil fuel addiction is a Frankenstein’s monster, sparing nothing and no one. All around us, we see clear signs that the monster has become master,”

The world could fall short of food by 2050 due to falling crop yields, insufficient investment in agricultural research and trade shocks, according to Joe Biden’s special envoy for food security, Dr Cary Fowler. Fowler, who is also known as the “father” of the Svalbard Global Seed Vault, a global store of seeds for the most significant crops, said studies by agricultural economists showed the world needed to produce 50-60% more food by 2050 in order to feed its growing population. But crop yields rates were projected to decline by between 3-12% as a result of global heating.
