L’humanité peut améliorer les niveaux de vie, réduire les inégalités et maintenir le réchauffement climatique en dessous d’une hausse de 2 °C, selon une vision ambitieuse de la survie de la planète rapportée la semaine dernière par The Guardian. À une époque marquée par l’angoisse écologique, c’est une affirmation remarquablement optimiste. Cet optimisme provient du Global Justice Report, élaboré par le World Inequality Lab de Thomas Piketty. […] Ce rapport va à contre-courant de l’époque actuelle. La démagogie anti-immigration, le retour en grâce des combustibles fossiles, les attaques contre le multilatéralisme et la captation du pouvoir par les milliardaires s’opposent tous à la capacité redistributive de l’État que le rapport juge nécessaire. Pourtant, l’équipe du professeur Piketty affirme que la décarbonation, la « sobriété » et l’égalité peuvent permettre à la majorité de mener une vie agréable.

The British-Canadian computer scientist often touted as a “godfather” of artificial intelligence has shortened the odds of AI wiping out humanity over the next three decades, warning the pace of change in the technology is “much faster” than expected. Prof Geoffrey Hinton, who this year was awarded the Nobel prize in physics for his work in AI, said there was a “10% to 20%” chance that AI would lead to human extinction within the next three decades.

Exclusive: Commission says alert would trigger coordinated international response that could help avoid millions dying. The climate crisis should be declared a global public health emergency by the World Health Organization, or millions more people will die unnecessarily, leading international experts have said. The independent pan-European commission on climate and health, which was convened by the WHO, concluded the climate crisis was such a worldwide threat to health that the WHO should declare it “a public health emergency of international concern” (Pheic).

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.
