When attempting to quantify future harms caused by carbon emissions and to set appropriate energy policies, it has been argued that the most important metric is the number of human deaths caused by climate change. Several studies have attempted to overcome the uncertainties associated with such forecasting. In this article, approaches to estimating future human death tolls from climate change relevant at any scale or location are compared and synthesized, and implications for energy policy are considered. Several studies are consistent with the “1000-ton rule,” according to which a future person is killed every time 1000 tons of fossil carbon are burned (order-of-magnitude estimate). If warming reaches or exceeds 2 °C this century, mainly richer humans will be responsible for killing roughly 1 billion mainly poorer humans through anthropogenic global warming, which is comparable with involuntary or negligent manslaughter. On this basis, relatively aggressive energy policies are summarized that would enable im

Homo sapiens has evolved to reproduce exponentially, expand geographically, and consume all available resources. For most of humanity’s evolutionary history, such expansionist tendencies have been countered by negative feedback. However, the scientific revolution and the use of fossil fuels reduced many forms of negative feedback, enabling us to realize our full potential for exponential growth. This natural capacity is being reinforced by growth-oriented neoliberal economics—nurture complements nature. Problem: the human enterprise is a ‘dissipative structure’ and sub-system of the ecosphere—it can grow and maintain itself only by consuming and dissipating available energy and resources extracted from its host system, the ecosphere, and discharging waste back into its host. The population increase from one to eight billion, and >100-fold expansion of real GWP in just two centuries on a finite planet, has thus propelled modern techno-industrial society into a state of advanced overshoot. We are consuming and

The sixth assessment report of the IPCC assessed that the Arctic is projected to be on average practically ice-free in September near mid-century under intermediate and high greenhouse gas emissions scenarios, though not under low emissions scenarios, based on simulations from the latest generation Coupled Model Intercomparison Project Phase 6 (CMIP6) models. Here we show, using an attribution analysis approach, that a dominant influence of greenhouse gas increases on Arctic sea ice area is detectable in three observational datasets in all months of the year, but is on average underestimated by CMIP6 models. By scaling models’ sea ice response to greenhouse gases to best match the observed trend in an approach validated in an imperfect model test, we project an ice-free Arctic in September under all scenarios considered. These results emphasize the profound impacts of greenhouse gas emissions on the Arctic, and demonstrate the importance of planning for and adapting to a seasonally ice-free Arctic in the near

L'assemblée générale d'actionnaires de Barclays, qui se tient mercredi à Londres, a à son tour été perturbée par des militants écologistes, après celles de BP ou TotalEnergies. D'après un communiqué de l'ONG Fossil Free London, une trentaine de militants originaires de plusieurs associations écologistes ont "infiltré l'AG du plus gros financier européen de carburants fossiles", la perturbant à de nombreuses reprises.

The collapse of modern societies has already begun. That is the conclusion of two years of research by the interdisciplinary team behind Breaking Together. How did it come to this? Because monetary systems caused us to harm each other and nature to such an extent it broke the foundations of our societies. So what can we do? This book describes people allowing the full pain of our predicament to liberate them into living more courageously and creatively.

L'entreprise Age of AI a rendu accessible au public FreedomGPT, une intelligence artificielle conversationnelle sans tabous ni limites.

Governments are ignoring calls to stop fossil fuel expansion—despite there being little time left to avoid the worst effects of global warming.

L’article du Monde intitulé « Contre les SUV en ville, la contestation enfle » relate les actions menées par des petits groupes d’activistes qui dégonflent les pneus la nuit. C’est triste à dire, mais en 2023, on en est toujours à parler de cela. Le dégonflage des pneus des SUV ou autres 4×4 est en effet encore un sujet de polémique, entre les activistes écologiques qui dénoncent ces véhicules « symboles d’émissions inutiles, effet de mode pour les riches » et les automobilistes extrémistes qui déplorent l’action « d’illuminés urbains démagos qui veulent se contenter du vélo. »

Dozens of people have been imprisoned, as changes in the law are used to curb protest. Is it part of a turn towards a more authoritarian state?

On ne compte plus les aides financières ou autres crédits d’impôts pour changer de voiture ou pour passer à la voiture électrique. Un projet de loi actuellement en cours de discussion en Californie aux USA va plus loin et propose de créer un crédit d’impôt pour les personnes qui ne possèdent pas de voiture afin d’encourager la population à se passer de voiture.

It is vital Moscow understands that escalation will not be risk-free, and expects a proportionate response

The frightful noise of gunfire, bombing and children’s screams in the cities of Ukraine reverberates across Europe. The full-scale Russian invasion launched last week is an unprovoked, heinous crime perpetrated against Ukraine’s citizens, their sovereign democratic state and all the free peoples of the world. The 24th of February is a day that will live in infamy. It will not be forgiven. It will surely never be forgotten.

Grieks econoom Yanis Varoufakis ziet drie redenen waarom de laatste klimaatconferentie opnieuw een debacle is geworden: een wereldwijd probleem van free-riding (de onrechtmatige overconsumptie van basisgrondstoffen door de grote bedrijven), het gebrek aan internationale coördinatie en ... het kapitalisme.

Une équipe d’experts dirigée par des chercheurs de l’University College London (UCL) a créé un modèle mathématique pour l’utilisation des voitures dans une ville, qui a démontré que les villes du futur doivent devenir totalement sans voitures pour rester vivables.

A team of experts led by University College London researchers created a mathematical model for car use within a city, which has demonstrated that cities of the future must become fully car-free in order to remain liveable.
