Guardian investigation reveals fossil fuel links of IPCC authors, with experts declaring the body’s conflict of interest policy ‘not fit for purpose’

Tim Benton, expert reconnu en sécurité alimentaire mondiale, afin de comprendre les causes de l'effondrement de nos systèmes alimentaires et les conditions nécessaires à la construction d'un système véritablement régénérateur. – Pourquoi le système alimentaire actuel est fondamentalement insoutenable – Que signifie concrètement le concept de « limites planétaires » – Le mythe de la croissance verte – Comment nos régimes alimentaires et nos systèmes agricoles doivent évoluer – Les 3 mécanismes qui nous empêchent d'avancer

A la hausse constante des prix alimentaires s'ajoutent les effets de plus en plus dramatiques du changement climatique et un monde de plus en plus instable. Serons-nous réellement capables de nourrir une population qui devrait bientôt atteindre 10 milliards. Le professeur Tim Benton, l’un des plus grands experts mondiaux des systèmes alimentaires, estime que notre modèle économique de croissance infinie sur une planète aux ressources finies est voué à s’effondrer. Mais quand cela se produira-t-il ? Qu’est-ce que cela signifie concrètement ? Et enfin, entrons-nous réellement dans une ère de famine ?

One of the biggest upheavals in a millennium is on its way, strengthened by the climate crisis. We need leaders who make things better not worse

In 1999, two colonels in China’s People’s Liberation Army wrote a strategy piece called Unrestricted Warfare. It gives guidance on how China can defeat the United States and the West in general. The 228 pages are a surprisingly easy and entertaining read. They’re also illuminating.

The term ‘Anthropocene’ was coined in recognition that human activities have ended the relatively stable environment of the Holocene epoch. However, its widespread adoption across the humanities, arts and sciences has led to diverse and sometimes incompatible definitions. In this Perspective, we argue for a stabilized definition of the Anthropocene epoch to help address contemporary environmental challenges, and explore various applications of the Anthropocene across disciplines. The Anthropocene epoch, with a proposed start point in 1952, underscores that human-driven global-scale environmental disruption differs from earlier human impacts of the Holocene, which did not cause such profound destabilization. This clear distinction enables quantitative and qualitative comparisons between the Holocene and Anthropocene epochs, as already utilized, for instance, within the planetary boundaries framework. As the Anthropocene Earth system transformation is systemic, political responses also need be systemic, rather

Chronic exposure to pesticide mixtures through diet is common, yet their combined metabolic effects and interactions with dietary factors remain unclear. We identified four pesticides prevalent in human exposure (imazalil, thiabendazole, boscalid, lambda-cyhalothrin) and assessed their combined impacts on hepatic metabolism and metabolic homeostasis using human liver cells and male mice fed standard chow or western diets. We found that the pesticide mixture induced metabolic perturbations in human hepatocytes. In addition, the pesticide mixture altered hepatic gene expression in chow-fed mice and exacerbated western diet-induced glucose intolerance, fasting hyperglycemia, and insulin resistance without affecting body weight or liver steatosis. These findings reveal that dietary context influences the metabolic consequences of pesticide mixtures, highlighting the need to consider nutritional status when evaluating environmental contaminant risks. Our results suggest that pesticide mixtures at reference doses m

What places on Earth are most resilient to global catastrophic risk (GCR)? We provide the first study of what locations are more resilient against the impacts of nuclear war, near-Earth objects, large-magnitude volcanic eruptions, large-scale cyberattacks, high altitude electromagnetic pulse, geomagnetic storms and pandemics. This shows there is no place on Earth which is resilient against all kinds of GCR. Australia shows resilience across the widest range of GCR scenarios in the literature we reviewed, but even for it, continued international cooperation and trade are essential. Across the different risks, common resilience factors that show up most are geographic isolation (e.g. islands), self-sufficiency (especially in food production), high governance quality (more democratic and lower inequality) and decentralization to mitigate single point catastrophic failures (e.g. impacting trade or food supply). Many of these factors stand in tension with each other and trade-offs are required to balance between d

Historically, the decarbonisation of aviation has lagged behind other modes of transport. However, the technology and policy base for change is finally taking off in Europe, and the region has a real chance to lead. But Europe needs to step on the accelerator, not the brake to maintain its global leadership for a clean transition for the sector.

Climate models simulate a wide range of 21st century warming for a given forcing scenario. Constraining this uncertainty is a central challenge in climate science because of its implications for climate policy and adaptation. The transient climate response (TCR) is a key idealized metric used to quantify future warming in response to an exponentially increasing CO2 concentration. Climate models span a range of 1.3–3 K for TCR. In attempts to constrain this range, emergent constraints on TCR based on historical temperature trends consistently pointed toward TCR values at the lower end of the range of models. However, recent evidence from trends in the short-wave and long-wave components of Earth's energy imbalance (EEI) at the top-of-atmosphere suggests that models with higher TCR lie closer to the observed EEI trends. Here, we reconcile this discrepancy and provide a revised range for TCR of 1.9–2.6 K. Using a statistical variability-filtering approach, we show that previous temperature-based constraints wer

Rising temperatures are set to drive up emissions from wildfires, fermenting wetlands, and melting permafrost, but these feedback loops are poorly captured in climate models. Scientists are racing to make sense of these emissions to gauge how much warming may lie ahead.

Emerging climate extremes should draw public attention to human-caused climate change. We expect unusual sea surface temperature (SST) and global warming the rest of this year to make 2026 hotter than 2024, despite 2024 being a peak El Nino year, while 2026 is only the lead-in year of an emerging El Nino. Beware the “surprise” record high being blamed on an extreme El Nino on top of global warming otherwise consistent with IPCC estimates. Instead, record warmth provides additional evidence of high climate sensitivity and increased net climate forcing in the past decade. These two factors are driving an unusual increase in global SSTs with major consequences. If you bear with our discussion to the end, you will find some possible good news. Figures in this post are continually updated on our website.[2] We are now on Substack[3].
