The Atlantic meridional overturning circulation (AMOC) is an important tipping element in the climate system. There is a large uncertainty whether the AMOC will start to collapse during the century under future climate change, as this requires long climate model simulations which are not always available. Here, we analyze targeted climate model simulations done with the Community Earth System Model (CESM) with the aim to develop a physics-based indicator for the onset of an AMOC tipping event. This indicator is diagnosed from the surface buoyancy fluxes over the North Atlantic Ocean and is performing successfully under quasi-equilibrium freshwater forcing, freshwater pulse forcing, climate change scenarios, and for different climate models. An analysis consisting of 25 different climate models shows that the AMOC could begin to collapse by 2063 (from 2026 to 2095, to percentiles) under an intermediate emission scenario (SSP2-4.5), or by 2055 (from 2023 to 2076, to percentiles) under a high-end emission scenar

Waterzuiveringsinstallaties zijn niet aangepast om bepaalde farmaceutische residuen af te breken. Wij consumenten kunnen ons steentje bijdragen door vervallen geneesmiddelen niet in de vuilnisbak te kieperen, maar naar de apotheek te brengen.

Micro- en nanoplastics duiken overal op, van aan de Noordpool tot in het menselijk lichaam. Wat al die piepkleine plasticdeeltjes met ons lichaam doen, is nog niet duidelijk, maar ze verhogen wellicht de kans op een resem aandoeningen. Wij vroegen 2 experten om hun tips om je blootstelling aan microplastics te beperken.

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.

Nestlé Waters est soupçonné d’avoir laissé plusieurs décharges sauvages de déchets plastiques - l’équivalent de 126 piscines olympiques - s’écouler dans les sols vosgiens. La multinationale suisse dément.

The world is losing fresh water at an unprecedented rate, two decades' worth of satellite data has revealed. Measurements from NASA's twin GRACE satellites and GRACE follow-on missions have shown that since 2002, the amount of land suffering from water loss has been increasing year on year by twice the area of the state of California. That includes the loss of water from surface reservoirs such as lakes and rivers and underground aquifers, which are an important source of drinking water around the globe.

Des taux de pollution aux microplastiques "incommensurables" ont été retrouvés dans les eaux Contrex et Hépar, selon le magistrat chargé de l'enquête préliminaire dans le cadre des poursuites contre Nestlé Waters concernant des décharges sauvages de déchets polluants dans les Vosges, révèle samedi Mediapart.

Nestlé Waters est poursuivi pour avoir stocké des déchets et maintenu quatre décharges sauvages dans les Vosges. Le procès se tiendra du 24 au 28 novembre. Des taux de pollution de microplastiques « incommensurables » ont été retrouvés dans les eaux Contrex et Hépar, selon le magistrat chargé de l’enquête préliminaire dans le cadre des poursuites contre Nestlé Waters concernant des décharges sauvages de déchets polluants dans les Vosges, révèle Mediapart dans un article paru samedi 9 août.

Hoewel er meer dan 6000 rivieren door het Nepalese landschap kronkelen, is het steeds moeilijker voor de Nepalezen om toegang te krijgen tot water. Er is steeds minder water, er is de klimaatverandering en de systemen om water te beheren zijn ook nog eens complex. Water was lange tijd een gedeeld en publiek goed in Nepal, maar die solidariteit maakt geleidelijk aan plaats voor conflict.

Rising temperatures are causing water to evaporate and driving humans to extract more groundwater, which is moving freshwater from the land to the seas and creating a "continental drying" trend..
