As the world’s largest gathering of Earth and space scientists swarmed a Washington venue last week, the packed halls have been permeated by an air of anxiety and even dread over a new Donald Trump presidency that might worsen what has been a bruising few years for science.
The climate and ecological crisis poses an unprecedented challenge, with scientists playing a critical role in how society understands and responds. This study examined how 27 environmentally concerned scientists from 11 countries construct the future in the context of climate change, applying a critical discursive psychology analysis. The degree to which the future is constructed as predetermined or transformable impacts both the urgency and scope of proposed actions. ...
Experts warn that mirror bacteria, constructed from mirror images of molecules found in nature, could put humans, animals and plants at risk of lethal infections
Science et conscience. Dans un vigoureux manifeste publié au Seuil, les Scientifiques en rébellion détaillent les raisons de leur passage à l’action et enjoignent leurs pairs à sortir d’une prétendue «neutralité» et désobéir avant qu’il ne soit trop tard.
AMOC collapse would bring severe global climate repercussions, with Europe bearing the brunt of the consequences.
As a six-year investigation into the Thwaites glacier in Antarctica wraps up, the scientists involved are pessimistic for the future of this glacier and the consequences for sea level rise
L’hebdomadaire britannique “New Scientist” fait sa une sur une promesse enthousiasmante concernant une maladie terrifiante : il s’agit aujourd’hui de vaincre la maladie d’Alzheimer grâce à la vaccination. Des essais sont en cours.
The net zero approach of the Paris agreement has become detached from reality as it increasingly relies on science fiction levels of speculative technology.
Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the first edition of a new systematic annual review.
Paranthropes, australopithèques, néandertaliens… Plus nous en apprenons sur les homininés, plus il devient difficile de définir ce qu’est un être humain, relève “New Scientist”.
The story of Greenland keeps getting greener—and scarier. A new study provides the first direct evidence that the center—not just the edges—of Greenland's ice sheet melted away in the recent geological past and the now-ice-covered island was then home to a green, tundra landscape.
À la veille des élections, des scientifiques mènent des actions dans la capitale pour alerter sur les risques climatiques. Les rapports alarmants sur le climat se multiplient, mais le monde politique n’en tient pas suffisamment compte aux yeux des scientifiques. Pour mieux se faire entendre, des chercheurs et académiques belges et internationaux ont donc décidé, en cette veille d’élections, d’opter pour la désobéissance civile.
Ce matin une vingtaine de scientifiques ont bloqué les entrées de la Commission européenne afin de réclamer la décroissance vue comme “la seule option pour sortir de l’impasse sociale et environnementale”
Human-caused climate crisis brought soaring temperatures across Asia, from Gaza to Delhi to Manila
Exclusive: Survey of hundreds of experts reveals harrowing picture of future, but they warn climate fight must not be abandoned

If the anomaly does not stabilise by August, ‘the world will be in uncharted territory’, says climate expert
Over the past year, there has been a vigorous debate among scientists – and more broadly – about whether global warming is “accelerating”.
An international team of scientists has warned against relying on nature providing straightforward 'early warning' indicators of a climate disaster, as new mathematical modeling shows new fascinating aspects of the complexity of the dynamics of climate. It suggests that the climate system could be more unpredictable than previously thought.
The Amazon rainforest is facing a barrage of pressures that might tip it into large-scale ecosystem collapse as soon as 2050, according to new research Wednesday warning of dire consequences for the region and the world. The Amazon, which holds more than 10 percent of the world's biodiversity, helps stabilize the global climate by storing the equivalent of around two decades of emissions of planet-warming carbon dioxide.
New paper claims unless demand for resources is reduced, many other innovations are just a sticking plaster Record heat, record emissions, record fossil fuel consumption. One month out from Cop28, the world is further than ever from reaching its collective climate goals. At the root of all these problems, according to recent research, is the human “behavioural crisis”, a term coined by an interdisciplinary team of scientists.
James Hansen says limit will be passed ‘for all practical purposes’ by May though other experts predict that will happen in 2030s
The European Commission has received an open letter signed by 110 academics, businesses, civil society organisations and research institutions urging the EU to separate emissions reductions, land-based sequestration and permanent carbon removals in the EU’s post-2030 climate framework. This separation should be at the heart of both the setting and the implementation of the 2040 target and associated plans.
Plus d’un millier de scientifiques spécialistes du climat exhortent le public à devenir des activistes Nous avons besoin de vous », déclare Scientist Rebellion, qui comprend les auteurs des rapports du GIEC sur les changements climatiques, alors que les diplomates se réunissent dans le cadre de la Cop28.
Humanity faces ‘devastating domino effects’ including mass displacement and financial ruin as planet warms
Referring to the Paris Agreement’s target of keeping Earth from warming no more than 1.5 degrees Celsius since the Industrial Revolution, the number has become a rallying cry for climate advocates and scientists, who say the goal is humanity’s best bet on avoiding the most catastrophic outcomes of climate change by the end of the century. Venturing even 0.5 degrees past that threshold could drastically increase the frequency and severity of extreme weather, biodiversity loss, famine and water scarcity, as well as make it more likely that tipping points accelerate warming further, climate scientists say.
