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

The Green Scare created precedents that today reach far beyond radical environmentalism, and threaten anyone willing to engage in direct action.

Extinction Rebellion says some members have been visited by agents claiming to be FBI amid Trump’s threats toward liberal groups

New year, new acronym! The newly established Intergovernmental Science-Policy Panel on Chemicals, Waste and Pollution (ISP-CWP) will meet in its first Plenary session from February 2-6 in Geneva, Switzerland. The Panel is designed to provide scientific assessments on chemicals, waste, and pollution to inform policymakers at national, regional, and international levels.

Melting glaciers, coastal areas wiped off the map and regular 40C heat in Europe. Climate experts warn the gloomy predictions of long term environmental change are no longer the future - they are already here. Last year was the third hottest on record, with the World Meteorological Organization this week warning that 2025 continued a run of “extraordinary” global temperatures. The EU has said the Paris climate agreement of 1.5C could be broken before 2030, a decade sooner than expected.

UN GEO report says ending this harm key to global transformation required ‘before collapse becomes inevitable’

Environmental defenders across Europe, South Caucasus and Central Asia are increasingly facing legal pressure, intimidation and attempts to restrict their work. Non-governmental organisations warn about a steady rise in SLAPP lawsuits (1), defamation cases, claims for compensation for alleged damages and other tactics intended to discourage public scrutiny of industrial, mining and development projects with a negative impact on environment. Civic oversight is becoming more difficult, especially for those who challenge powerful economic or political interests.

We propose a new paradigm, as toxicology currently lacks the proper perspective. From the 1950s to the 1970s, at least one-third of all toxicological testing in the United States, including for chemicals and drugs, was misleading scientists, and this worldwide issue persists today. Moreover, petroleum-based waste and heavy metals have been discovered in pesticide and plasticizer formulations. These contaminations have now reached all forms of life. Widespread exposure to chemical mixtures promotes health and environmental risks. We discovered that pesticides have never undergone long-term testing on mammals in their full commercial formulations by regulatory authorities or the pesticide industry; instead, only their declared active ingredients have been assessed, contrary to environmental law recommendations. The ingredients of these formulations are not fully disclosed, yet the formulations are in general at least 1000 times more toxic at low environmentally relevant doses than the active ingredients alone u

EU officials warn climate breakdown and wildlife loss ‘are ruining ecosystems that underpin the economy’ […] The European way of life is being jeopardised by environmental degradation, a report has found, with EU officials warning against weakening green rules. The continent has made “important progress” in cutting planet-heating pollution, according to the European Environment Agency, but the death of wildlife and breakdown of the climate are ruining ecosystems that underpin the economy.

Why Environmental Writing Isn’t Resonating As Much Anymore Active hope, not optimism. And why facts alone no longer move people. Environmental pieces aren’t landing like they used to. Writers, researchers, and activists are noticing the shift: climate content that once sparked engagement now fades into the background. The question isn’t whether people care about the planet — it’s that many readers are moving past narratives of awareness and individual action (or at least I think they should!). They want to understand power. They want to understand systems. They want hope rooted in collective transformation, not optimism sold as personal therapy. We Know the Planet Is Dying. So Now What?

Purpose Animal emissions account for nearly 60% of total greenhouse gas emissions from the livestock sector. To estimate these emissions, the Food and Agriculture Organization of the United Nations (FAO) developed a dedicated module within the Global Livestock Environmental Assessment Model (GLEAM). Although previous studies have explored selected inputs for specific animals and emission types, a comprehensive analysis of all 92 inputs (parameters and emission factors) had not been conducted. This study aimed to identify the most influential inputs affecting ruminant emissions in GLEAM.

Facebook and other social media platforms need to act to stop intimidation and harassment of environmental protectors

The criminalization and repression of climate and environmental activists have intensified globally in the past few years.1 These are forms of backlash against often impactful social movements. The repressive wave has sparked major concerns in many quarters, with the UN secretary general, the UN special rapporteur on environmental defenders, and many nongovernmental organizations (NGOs), politicians, and social movements speaking out against it.2 In this article I will draw on findings from a University of Bristol project that I led on this topic.3 Driven by a combination of state and corporate actors, the repression of climate and environmental protest is a truly worldwide phenomenon that takes place across the Global North and South.

Nonylphenol is a toxic xenobiotic compound classified as an endocrine disrupter capable of interfering with the hormonal system of numerous organisms. It originates principally from the degradation of nonylphenol ethoxylates which are widely used as industrial surfactants. Nonylphenol ethoxylates reach sewage treatment works in substantial quantities where they biodegrade into several by-products including nonylphenol. Due to its physical–chemical characteristics, such as low solubility and high hydrophobicity, nonylphenol accumulates in environmental compartments that are characterised by high organic content, typically sewage sludge and river sediments, where it persists.

Despite concerns over the environmental impacts of AI models, it's surprisingly hard to find precise, reliable data on the CO2 emissions and water use for many major large language models. French model-maker Mistral is seeking to fix that this week, releasing details from what it calls a first-of-its-kind environmental audit "to quantify the environmental impacts of our LLMs."

While green technologies can hypothetically make supply chains more efficient, enhanced efficiency often leads to more production and economic growth, not less.

The world's largest polluters are also the safest from the environmental damage they help create—while the countries least to blame face the greatest threats, including the increased possibility of violent conflict.

Anti-environmentalism is gaining ground. Attacks on the net zero goal and hostility to conservation measures and anti-pollution targets are becoming more common. And, as recent election results have shown, these tactics are reshaping politics in Britain and across the west.

The Global Justice Project is a collective research initiative developed by the World Inequality Lab. Combining comparative historical data series from the World Inequality Database with global input-output tables, environmental accounts, labour force surveys and other sources, the project explores what a just distribution of socio-economic and environmental resources could look like at the global level from 2025 to 2100 – both between and within countries – in a way that is compatible with planetary boundaries. The project partly builds on the analysis and proposals set out in Thomas Piketty’s Brief History of Equality, extending them into a broader and more comprehensive global framework. The Global Justice Project is now available to explore on a dedicated website, that includes an interactive tool to explore the distributional pathways and climate scenarios behind the report.

Microplastics have been found for the first time in human ovary follicular fluid, raising a new round of questions about the ubiquitous and toxic substances’ potential impact on women’s fertility. The new peer-reviewed research published in Ecotoxicology and Environmental Safety checked for microplastics in the follicular fluid of 18 women undergoing assisted reproductive treatment at a fertility clinic in Salerno, Italy, and detected them in 14.

Donald Trump’s administration is to reconsider the official finding that greenhouse gases are harmful to public health, a move that threatens to rip apart the foundation of the US’s climate laws, amid a stunning barrage of actions to weaken or repeal a host of pollution limits upon power plants, cars and waterways.

As fossil fuel interests attack climate accountability litigation, environmental advocates have sounded a new warning that they are pursuing a path that would destroy all future prospects for such cases. Nearly 200 advocacy groups have urged Democratic representatives to “proactively and affirmatively” reject potential industry attempts to obtain immunity from litigation.

Previous health impact assessments of temperature-related mortality in Europe indicated that the mortality burden attributable to cold is much larger than for heat. Questions remain as to whether climate change can result in a net decrease in temperature-related mortality. In this study, we estimated how climate change could affect future heat-related and cold-related mortality in 854 European urban areas, under several climate, demographic and adaptation scenarios. We showed that, with no adaptation to heat, the increase in heat-related deaths consistently exceeds any decrease in cold-related deaths across all considered scenarios in Europe. Under the lowest mitigation and adaptation scenario (SSP3-7.0), we estimate a net death burden due to climate change increasing by 49.9% and cumulating 2,345,410 (95% confidence interval = 327,603 to 4,775,853) climate change-related deaths between 2015 and 2099. This net effect would remain positive even under high adaptation scenarios, whereby a risk attenuation of 50%

British police arrest environmental protesters at nearly three times the global average rate, research has found, revealing the country as a world leader in the legal crackdown on climate activism.

Hastened reviews of compounds as industry ramps up could increase pollution from likely toxic chemicals. The Environmental Protection Agency is quietly fast tracking approval of new PFAS “forever chemicals” for use by the semiconductor industry at the same time the agency is publicly touting increased scrutiny of new PFAS and other chemicals.

Microplastics are ubiquitous environmental contaminants for which there are documented human exposures, but there is a paucity of research evaluating their impacts on human health. We conducted a rapid systematic review using the “Navigation Guide” systematic review method. We searched four databases in July 2022 and April 2024 with no restriction on the date.

In this article, we’ll see why cascading disruptions of environmental and political systems are entangled and mutually reinforcing. We’ll also try to identify the next stages of global collapse, and explore the options for individuals and communities seeking to survive and to prevent as much harm and suffering as possible.

A short definition of the polycrisis, including global environmental, geopolitical, and economic aspects.

Trump could reverse the nation’s progress on climate change, but rolling back the Biden administration’s significant climate successes could be a low, slow and difficult process...

A Climate Rights International report exposes the increasingly heavy-handed treatment of climate activists in Australia, Germany, France, the Netherlands, Sweden, the UK and the US. It found the crackdown in these countries – including lengthy prison sentences, preventive detention and harassment – was a violation of governments’ legal responsibility to protect basic rights to freedom of expression, assembly, and association. It also highlights how these same governments frequently criticise regimes in developing countries for not respecting the right to protest peacefully.

The EU is being sued for failing to set ambitious climate targets in sectors that contribute more than half of the bloc’s total greenhouse gas emissions.

Under current emission trajectories, temporarily overshooting the Paris global warming limit of 1.5 °C is a distinct possibility. Permanently exceeding this limit would substantially increase the probability of triggering climate tipping elements. Here, we investigate the tipping risks associated with several policy-relevant future emission scenarios, using a stylised Earth system model of four interconnected climate tipping elements.

Unesco joint research dating back 15 years found violence and intimidation against about 750 reporters and 44 murders

Dr Sarah Benn has long been concerned about the climate crisis, diligently recycling until she was “blue in the face”. But the rise of the climate activist group Extinction Rebellion in 2019 inspired her and her husband to go further. “We thought: well, if we don’t do it then who else is going to?”

Le débat sur les nouveaux OGM est biaisé par les lobbies qui défendent toute une série d’intérêts économiques. A la faveur de sa présidence européenne, la Belgique doit se positionner dans ce dossier en facilitant l’élaboration d’une politique européenne qui donne la priorité à l’équité, à l’autonomie des agriculteur.e.s, à la santé publique et à l’environnement.

Anthropogenic emissions drive global-scale warming yet the temperature increase relative to pre-industrial levels is uncertain. Using 300 years of ocean mixed-layer temperature records preserved in sclerosponge carbonate skeletons, we demonstrate that industrial-era warming began in the mid-1860s, more than 80 years earlier than instrumental sea surface temperature records. The Sr/Ca palaeothermometer was calibrated against ‘modern’ (post-1963) highly correlated (R2 = 0.91) instrumental records of global sea surface temperatures, with the pre-industrial defined by nearly constant (<±0.1 °C) temperatures from 1700 to the early 1860s. Increasing ocean and land-air temperatures overlap until the late twentieth century, when the land began warming at nearly twice the rate of the surface oceans. Hotter land temperatures, together with the earlier onset of industrial-era warming, indicate that global warming was already 1.7 ± 0.1 °C above pre-industrial levels by 2020. Our result is 0.5 °C higher than IPCC estim

Link to climate activism is seven times stronger for anger than it is for hope, say Norwegian researchers

Permafrost and glaciers in the high Arctic form an impermeable ‘cryospheric cap’ that traps a large reservoir of subsurface methane, preventing it from reaching the atmosphere. Cryospheric vulnerability to climate warming is making releases of this methane possible. On Svalbard, where air temperatures are rising more than two times faster than the average for the Arctic, glaciers are retreating and leaving behind exposed forefields that enable rapid methane escape. Here we document how methane-rich groundwater springs have formed in recently revealed forefields of 78 land-terminating glaciers across central Svalbard, bringing deep-seated methane gas to the surface. Waters collected from these springs during February–May of 2021 and 2022 are supersaturated with methane up to 600,000 times greater than atmospheric equilibration. Spatial sampling reveals a geological dependency on the extent of methane supersaturation, with isotopic evidence of a thermogenic source. We estimate annual methane emissions from prog

World Bank says subsidies costing as much as $23m a minute must be repurposed to fight climate crisis...

Flash drought, characterized by unusually rapid drying, can have substantial impact on many socioeconomic sectors, particularly agriculture. However, potential changes to flash drought risk in a warming climate remain unknown. In this study, projected changes in flash drought frequency and cropland risk from flash drought are quantified using global climate model simulations. We find that flash drought occurrence is expected to increase globally among all scenarios, with the sharpest increases seen in scenarios with higher radiative forcing and greater fossil fuel usage. Flash drought risk over cropland is expected to increase globally, with the largest increases projected across North America (change in annual risk from 32% in 2015 to 49% in 2100) and Europe (32% to 53%) in the most extreme emissions scenario. Following low-end and medium scenarios compared to high-end scenarios indicates a notable reduction in annual flash drought risk over cropland. Flash droughts are projected to become more frequent unde

Tiny plastic particles can travel worldwide, ending up in urban, rural, and remote areas. They take an even faster transport pathway than oceanic currents: the atmosphere.

Beware of these three false solutions to climate change: carbon capture utilization and storage (CCUS), hydrogen and offsets.

Overall, however, the climate crisis is bleaker than it has ever been. In October, a slew of reports laid bare how close the planet had neared to irreversible climate breakdown, with one UN study stating there was “no credible pathway in place to 1.5C”, the internationally agreed limit for global heating, and that progress on cutting carbon emissions was “woefully inadequate”.

A large majority of the UK public supports nonviolent direct action to protect the environment, according to an opinion poll. People also strongly backed solar power on farmland and opposed fracking. The poll indicates the unpopularity of a recent swathe of government policies, with more than twice as many people saying they trusted Labour to protect the environment as said they trusted the Conservatives.

Campaigners say protesters arrested for blocking roads getting ‘lost in prison system’ while on remand. Speaking from inside the jail, he said: “The only good thing about my situation is that it seems to give an extra platform for my views. I spend most afternoons writing speeches and they have been read out all over the world – Italy, Sweden, Canada.”

Human activity is putting the Earth on a trajectory towards environmental collapse. The SDGs were adopted in2015 to reconcile human activity with planetary boundaries. So far, the SDGs have not lived up to their promise in European Union member states. Most EU countries have seen socioeconomic development alongside environmental degradation. Progress towards environmental sustainability only occurs in countries with slow or negative socioeconomic trends.

Researchers have been able to cut their carbon footprint by jetting off to fewer international conferences, but physicists working on large-scale experiments may also have to consider the significant environmental impact of the computer power they require. Michael Allen investigates

Only rarely does a book truly change the world. In the nineteenth century, such a book was Charles Darwin’s On the Origin of Species. For the twentieth century, it was The Limits to Growth. Not only did this best-selling 1972 publication help spur the environmental movement, but it showed that the underlying dynamics of the modern industrial world are unsustainable on the timescale of a couple of human lifetimes. This was profoundly important information, and it was delivered credibly and clearly, so that every policy maker could understand it.

The Belgian Institute for Sustainable IT is a think and do tank founded in 2020, based on its French equivalent the INR. Our aim is to bring together Belgian companies, organizations and individuals, and help them succeed their digital transition while reducing the environmental and social footprint of their IT services and usages. Thanks to the support of our members and of public authorities, we promote digital technologies and services that are more sustainable, inclusive and ethical.

Wealthy companies are using the facade of ‘nature-based solutions’ to enact a great carbon land grab

We submit that the safe operating space of the planetary boundary of novel entities is exceeded since annual production and releases are increasing at a pace that outstrips the global capacity for assessment and monitoring. The novel entities boundary in the planetary boundaries framework refers to entities that are novel in a geological sense and that could have large-scale impacts that threaten the integrity of Earth system processes. We review the scientific literature relevant to quantifying the boundary for novel entities and highlight plastic pollution as a particular aspect of high concern. An impact pathway from production of novel entities to impacts on Earth system processes is presented.

Le glyphosate fait encore parler de lui. Le pesticide le plus utilisé dans le monde, et particulièrement en France, est au centre d’une nouvelle recherche. L’étude publiée mercredi dans la revue Environmental Science and Pollution Research et menée sur 6 848 personnes partout en France métropolitaine et à la Réunion est sans équivoque : la quasi-totalité des urines analysées sont contaminées au glyphosate.

Des sommets aux profondeurs. Après les microplastiques découverts mardi sur le Pic du Midi, dans les Pyrénées, voilà ces minuscules particules détectées dans nos selles. Et particulièrement lorsque l’on est atteint de troubles intestinaux. Comme le révèle le Guardian, une étude publiée dans la revue Environmental Science & Technology montre que les personnes atteintes d’une maladie inflammatoire de l’intestin (MII) présentent 50% de microplastiques en plus dans leurs selles.
