Do we really want to play dice with our planet?

Nearly every indicator of climate change is flashing red. But we still hold the tools available to bring the planet back into balance

Cet article rapporte la difficulté du secteur manufacturier en Grande Bretagne à faire face à l’augmentation du cout de l'énergie. Dans l'ombre de cet article apparait ce qui sera la réalité à un moment donné, sans pétrole bon marché, l'industrie manufacturière ne peut pas fonctionner dans les conditions actuelles. Le contrat social sera rompu et il faudra réinventer une manière de vivre ensemble. La situation en Grande Bretagne est peut-être exacerbée par le Brexit et la situation insulaire mais elle est l'avant-poste de ce qui attend une bonne part du monde industrialisé, à moins de relancer le charbon avec toutes les conséquences sur le dérèglement climatique et la santé des personnes que nous connaissons.

Four months into US oil blockade, Cubans see island drained as state electric company fights to provide even a few hours of power a day Ruaridh Nicoll in Havana - The doctor called from the darkness, a shadowy figure sitting on the stoop of his apartment building. “I want to tell you we’ve been four days without light,” he said. “And without electricity, water is also a problem. And there are mosquitoes everywhere.”

The system of ocean current that moves heat in the Atlantic Ocean plays a key role in regulating climate. Today’s monitoring of it may be discontinued...

Photosynthesis does not always result in wood growth, a key factor in carbon dioxide sequestration

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.

Our roadmap has been shaped by experts across the world, from UN agencies to grassroots movements. We call on political leaders at all levels to use it

Global effort needed to limit effects of pollution, industrial fishing and climate crisis, World Ocean Assessment says

The Global Justice Report offers a hopeful bargain: tax extreme wealth and replace consumer excess with social and economic security for all

Weather models project a potentially strong El Niño this year, which could spell disaster for heatwave-hit India, drench China and hurt agriculture across south-east Asia

La construction d'un datacenter en Utah a entrainé une opposition farouche des habitants. La course à l'IA repose la question de l'équilibre entre technologie et ressources limitées en eau, en terres arables et terres rares, en électricité. De nombreux datacenter vont utiliser des énergies fossiles.

World is approaching point where no one can shut down a rogue AI, says director of body behind research

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).

Norway’s energy minister says country has a ‘responsibility’ to address shortfalls caused by wars in Ukraine and Middle East

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.

Analysis of six extreme heatwaves found when temperature and humidity were accounted for, all were potentially deadly for older people

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.
