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.
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.
Human-caused climate crisis brought soaring temperatures across Asia, from Gaza to Delhi to Manila

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.
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.

La COP28 est une mascarade que les scientifiques refusent de cautionner. Les scientifiques en rébellion ont tenu à Bordeaux une contre-COP.
the starkest warning yet that human activity is pushing Earth into a climate crisis that could threaten the lives of up to 6 billion people this century, stating candidly: “We are afraid of the uncharted territory that we have now entered.” Writing in the journal Biosciences, the coalition of 12 researchers, spanning North America, Europe and Asia, state in unusually stark language: “As scientists, we are increasingly being asked to tell the public the truth about the crises we face in simple and direct terms. The truth is that we are shocked by the ferocity of the extreme weather events in 2023.”
Catastrophic climate change and the collapse of human societies By Josep Peñuelas, Sandra Nogué National Science Review, Volume 10, Issue 6, June 2023 The scientific community has focused the agend…
Previously, anthropogenic ecological overshoot has been identified as a fundamental cause of the myriad symptoms we see around the globe today from biodiversity loss and ocean acidification to the disturbing rise in novel entities and climate change. In the present paper, we have examined this more deeply, and explore the behavioural drivers of overshoot, providing evidence that overshoot is itself a symptom of a deeper, more subversive modern crisis of human behaviour. We work to name and frame this crisis as ‘the Human Behavioural Crisis’ and propose the crisis be recognised globally as a critical intervention point for tackling ecological overshoot. We demonstrate how current interventions are largely physical, resource intensive, slow-moving and focused on addressing the symptoms of ecological overshoot (such as climate change) rather than the distal cause (maladaptive behaviours). We argue that even in the best-case scenarios, symptom-level interventions are unlikely to avoid catastrophe or achieve more

Going beyond climate disruption, the report by the Earth Commission group of scientists presents disturbing evidence that our planet faces growing crises of water availability, nutrient loading, ecosystem maintenance and aerosol pollution. These pose threats to the stability of life-support systems and worsen social equality.
In early May, a groundbreaking study from the University of California, San Francisco of 171 pregnant women found more than 9 in 10 had measurable amounts of 19 different chemicals and pesticides in their bodies. Researchers said many of those substances pass through the placenta and into developing fetuses, adding evidence to a National Institutes of Health report that warned babies are born "pre-polluted" with chemicals.
Abusive, often violent tweets denying the climate emergency have become a barrage since Elon Musk acquired the platform, say UK experts
An investigation by conservationists has found evidence that deep-seabed mining of rare minerals could cause “extensive and irreversible” damage to the planet.The report, to be published on Monday by the international wildlife charity Fauna & Flora, adds to the growing controversy that surrounds proposals to sweep the ocean floor of rare minerals that include cobalt, manganese and nickel. Mining companies want to exploit these deposits – which are crucial to the alternative energy sector – because land supplies are running low, they say.

The excessive use of phosphorus is depleting reserves vital to global food production, while also adding to the climate crisis
An unprecedented rise in plastic pollution has been uncovered by scientists, who have calculated that more than 170tn plastic particles are afloat in the oceans. They have called for a reduction in the production of plastics, warning that “cleanup is futile” if they continue to be pumped into the environment at the current rate.

Lorsque la Russie a assumé la présidence tournante du Conseil de l’Arctique en 2021, Moscou a présenté une proposition ambitieuse à cet organisme de huit pays soucieux de l’environnement. Au cours des 14 prochaines années, elle fera remonter des profondeurs de l’Arctique un ensemble toxique de déchets nucléaires rouillés – y compris deux sous-marins nucléaires entiers – qui ont été coulés pendant l’ère soviétique.

An international study on the future of insects under climate change scenarios has found the loss of insects will drastically reduce the ability of humankind to build a sustainable future. "A growing body of evidence shows many populations of insects are declining rapidly in many places. These declines are of profound concern, with terms like an emerging 'insect apocalypse' being increasingly used by the media and even some scientists to describe this phenomenon," Laurance said.
An international team of researchers have sounded new alarm bells about the changing chemistry of the western region of the Arctic Ocean after discovering acidity levels increasing three to four times faster than ocean waters elsewhere. The team, which includes University of Delaware marine chemistry expert Wei-Jun Cai, also identified a strong correlation between the accelerated rate of melting ice in the region and the rate of ocean acidification, a perilous combination that threatens the survival of plants, shellfish, coral reefs and other marine life and biological processes throughout the planet's ecosystem.
Ecosystems rely on interconnectedness — bees pollinate the flowers, predators eats prey, and so on. But these webs, though highly evolved, can be delicate. One link goes missing, and a ripple effect is felt throughout the entire system. As more species are lost, that balance becomes increasingly fragile, sometimes to the point of collapse.
