Human pressures have pushed the Earth system deep into the Anthropocene, threatening its stability, resilience and functioning. The Planetary Boundaries (PB) framework emerged against these threats, setting safe levels to the biophysical systems and processes that, with high likelihood, ensure life-supporting Holocene-like conditions. In this Review, we synthesize PB advancements, detailing its emergence and mainstreaming across scientific disciplines and society. The nine PBs capture the key functions regulating the Earth system. The safe operating space has been transgressed for six of these. PB science is essential to prevent further Earth system risks and has sparked new research on the precision of safe boundaries. Human development within planetary boundaries defines sustainable development, informing advances in social sciences. Each PB translates to a finite budget that the world must operate within, requiring strengthened global governance. The PB framework has been adopted by businesses and informed

Abstract. We review how the international modelling community, encompassing integrated assessment models, global and regional Earth system and climate models, and impact models, has worked together over the past few decades to advance understanding of Earth system change and its impacts on society and the environment and thereby support international climate policy. We go on to recommend a number of priority research areas for the coming decade, a timescale that encompasses a number of newly starting international modelling activities, as well as the IPCC Seventh Assessment Report (AR7) and the second UNFCCC Global Stocktake. Progress in these priority areas will significantly advance our understanding of Earth system change and its impacts, increasing the quality and utility of science support to climate policy. We emphasize the need for continued improvement in our understanding of, and ability to simulate, the coupled Earth system and the impacts of Earth system change. There is an urgent need to investiga
We are on the brink of an irreversible climate disaster. This is a global emergency beyond any doubt. Much of the very fabric of life on Earth is imperiled. We are stepping into a critical and unpredictable new phase of the climate crisis. For many years, scientists, including a group of more than 15,000, have sounded the alarm about the impending dangers of climate change driven by increasing greenhouse gas emissions and ecosystem change (Ripple et al. 2020).
Record emissions, temperatures and population mean more scientists are looking into possibility of societal collapse, report says

Het is vandaag Earth Overshoot Day: vanaf vandaag tot het einde van het jaar verbruikt de wereldbevolking meer dan onze planeet op een jaar aan grondstoffen en diensten kan leveren. Voor onze huidige levensstijl zijn eigenlijk 1,7 planeten aarde nodig, en dat kan uitdraaien op een ramp, waarschuwen experts. Earth Overshoot Day valt dit jaar ook een dag vroeger dan vorig jaar.
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.
A carbon bomb is any fossil fuel extraction project that will generate more than one gigatonne of carbon dioxide (1GtCO2) over its remaining life.
Le satellite EarthCARE de l'Agence spatiale européenne a pris son envol mardi depuis la base de Vandenberg en Californie, à bord d'une fusée Falcon 9 de SpaceX. Sa mission : explorer en détail les effets des nuages sur le climat, un phénomène encore mal compris.
Evidence shows a continuing increase in the frequency and severity of global heatwaves1,2, raising concerns about the future impacts of climate change and the associated socioeconomic costs3,4. Here we develop a disaster footprint analytical framework by integrating climate, epidemiological and hybrid input–output and computable general equilibrium global trade models to estimate the midcentury socioeconomic impacts of heat stress. We consider health costs related to heat exposure, the value of heat-induced labour productivity loss and indirect losses due to economic disruptions cascading through supply chains. Here we show that the global annual incremental gross domestic product loss increases exponentially from 0.03 ± 0.01 (SSP 245)–0.05 ± 0.03 (SSP 585) percentage points during 2030–2040 to 0.05 ± 0.01–0.15 ± 0.04 percentage points during 2050–2060. By 2060, the expected global economic losses reach a total of 0.6–4.6% with losses attributed to health loss (37–45%), labour productivity loss (18–37%) and i
Ontdek het 4,5 miljard jaar oude verhaal van de planeet die we onze thuis noemen: de aarde. Vandaag de dag is de aarde een planeet waarop 8 miljard mensen wonen, mensen die een grotere invloed hebben op de vormgeving van ons aardoppervlak dan de meeste natuurlijke processen. Dramatische wendingen in onze geschiedenis hebben gemaakt dat de mens controle heeft gekregen over de natuur. Maar het is noodzakelijk om hieruit ook de nodige lessen te trekken, voor het te laat is.

A UN meeting this week considered a motion on a suite of technologies known as ‘solar radiation modification’, but no consensus could be reached on the controversial topic.

Juristen van ClientEarth hebben, samen met 14 ngo's, nieuwe juridische stappen ondernomen tegen INEOS, nu de petrochemiereus zijn plannen doorzet om Europa's grootste plasticproject te bouwen. De milieuorganisaties hebben vandaag een rechtszaak aangespannen tegen de Vlaamse overheid. Deze zaak markeert een nieuwe fase in de langdurige juridische strijd van de groep milieuorganisaties tegen 'Project One' van INEOS.
Even recapituleren. Op zondag 7 jan 2024 kreeg Ineos – na een verrassend positief advies van ANB – zijn huidige vergunning van de Vlaamse Regering. De vorige was onderuit gehaald op grond van de beroepsprocedure die de provincie Noord-Brabant had aangespannen. VlaReg werd toen door de Raad voor Vergunningenbetwistingen op de vingers getikt voor haar lossepolswerk aangaande de verwachte stikstofdepositie van Project One voorbij de Nederlandse grens. En al stond het in de sterren geschreven dat zowel de provincie Noord-Brabant als de provincie Zeeland opnieuw beroep zouden aantekenen en dat ook Client Earth opnieuw met een beroep ten gronde zou komen, toch startte Ineos op 8 januari full speed de constructiewerken in Lillo. Evident met de bedoeling om de weg van de voldongen feiten te kiezen en om de beroepsprocedures in snelheid te pakken. Mocht er een kink in de kabel komen, dan was er altijd nog de overheidswaarborg van een half miljard, waarvan overigens al 250 miljoen zijn geactiveerd. Poker à la Ratcliffe
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
