Subsurface Temperature Profiles

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.

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.

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.

The planetary boundaries concept presents a set of nine planetary boundaries within which humanity can continue to develop and thrive for generations to come

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

Overall losses from natural disasters in 2023: US$ 250bn; more than 74,000 fatalities Insured global losses of US$ 95bn close to five-year average (US$ 105bn) and above the ten-year average (US$ 90bn) Earthquake in Turkey and Syria was the year’s most devastating humanitarian disaster Thunderstorms in North America and Europe more destructive than ever before: overall losses of US$ 76bn; insured losses US$ 58bn 2023 was the hottest year ever, with a large number of regional records broken

An easy way to start a long, heated debate is to mention global population. Thomas Malthus famously ignited furious arguments in the eighteenth century when

Humanity faces ‘devastating domino effects’ including mass displacement and financial ruin as planet warms

Plastic waste in aquatic environments may be severely disrupting the reproductive behavior of marine animals. 

When Rishi Sunak granted 27 new North Sea licences this week, he wasn’t thinking about the survival of the living world, says Guardian columnist George Monbiot

September 2023 smashed the prior global temperature record. Hand-wringing about the magnitude of the temperature jump in September is not inappropriate, but it is more important to investigate the role of aerosol climate forcing – which we chose to leave unmeasured – in global climate change. Global temperature during the current El Nino provides a potential indirect assessment of change of the aerosol forcing. Global temperature in the current El Nino, to date, implies a strong acceleration of global warming for which the most likely explanation is a decrease of human-made aerosols as a result of reductions in China and from ship emissions. The current El Nino will probably be weaker than the 1997-98 and 2015-16 El Ninos, making current warming even more significant. The current near-maximum solar irradiance adds a small amount to the major “forcing” mechanisms (GHGs, aerosols, and El Nino), but with no long-term effect. More important, the long dormant Southern Hemisphere polar amplification is probably com

Ahead of the UN’s SDG Summit (18-19 September), ground-breaking analyses shows how by enacting five ‘extraordinary turnarounds’ SDGs implementation can be accelerated.

This planetary boundaries framework update finds that six of the nine boundaries are transgressed, suggesting that Earth is now well outside of the safe operating space for humanity. Ocean acidification is close to being breached, while aerosol loading regionally exceeds the boundary. Stratospheric ozone levels have slightly recovered. The transgression level has increased for all boundaries earlier identified as overstepped. As primary production drives Earth system biosphere functions, human appropriation of net primary production is proposed as a control variable for functional biosphere integrity. This boundary is also transgressed. Earth system modeling of different levels of the transgression of the climate and land system change boundaries illustrates that these anthropogenic impacts on Earth system must be considered in a systemic context.

First complete ‘scientific health check’ shows most global systems beyond stable range in which modern civilisation emerged

La séquestration du CO2 dans les sols agricoles est présentée comme une excellente stratégie pour atténuer le changement climatique. Mais est-ce réellement le cas ? Plusieurs pédologues ont exprimé leurs doutes lors de la Conférence sur les sols de Wageningen le 29 août.

Bonn and Geneva, 6 September 2023 (ECMWF and WMO) - Earth just had its hottest three months on record, according to the European Union-funded Copernicus Climate Change Service (C3S) implemented by ECMWF. Global sea surface temperatures are at unprecedented highs for the third consecutive month and Antarctic sea ice extent remains at a record low for the time of year.

Morgen, op 2 augustus, zullen alle hulpbronnen al opgebruikt zijn die de planeet in een jaar kan genereren. Als iedereen aan het tempo van de Belgen zou consumeren, zou “Earth Overshoot Day” zelfs al op 26 maart gevallen zijn, zegt het Wereldnatuurfonds.

Climate breakdown and crop losses threaten our survival, but the ultra-rich find ever more creative ways to maintain the status quo, says Guardian columnist George Monbiot

As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research published in Nature Geoscience. The study, led by researchers from the University of Cambridge and the University Center in Svalbard, Norway, identified large stocks of methane gas leaking from groundwater springs unveiled by melting glaciers.

Going beyond climate disruption, the report by the Earth Commission group of scientists presents disturbing evidence that our planet faces growing crises of water availability, nutrient loading, ecosystem maintenance and aerosol pollution. These pose threats to the stability of life-support systems and worsen social equality.

Earth Day - Dag van de Aarde - is één van de grootste milieu protestbewegingen ter wereld. Het begon in 1970 en vindt elk jaar plaats op 22 april. Ongeveer 1 miljard mensen uit meer dan 190 landen nemen deel aan demonstraties, projecten e...

Several nations plan to build new coal power plants, with China alone approving nearly 100 gigawatts. Each gigawatt is the equivalent of installing more than 3 million solar panels.

Une étude démographique commandée par le Club de Rome présente de nouvelles perspectives sur l’évolution de la population mondiale d’ici la fin du siècle. Cette étude réalisée par Earth4all revoit en effet à la baisse les projections sur le nombre d’habitants qui peupleront la Terre en 2100. Alors que les démographes de l’ONU estiment que, à ce moment-là, notre planète comptera 9,7 milliards d’humains, le rapport d’Earth4all avance un chiffre plus faible compris entre 6  et 7,3 milliards.

Researchers found that exceeding the 2C increase has a 50% chance of happening by mid-century

Energy and extractive industry giants are targeting environmentalists with racketeering charges.

Fossil fuels, fisheries and farming: the world’s most destructive industries are protected – and subsidised – by governments

Flash droughts can develop within a few weeks, causing water shortages, damaging crops and worsening fire risks.

MIT researchers have confirmed that Earth harbors a “stabilizing feedback” mechanism that acts over hundreds of thousands of years to keep global temperatures within a steady, habitable range.“On the one hand, it’s good because we know that today’s global warming will eventually be canceled out through this stabilizing feedback,” says Constantin Arnscheidt, a graduate student in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS). “But on the other hand, it will take hundreds of thousands of years to happen, so not fast enough to solve our present-day issues.”

Bewoners uit heel België spannen een rechtszaak aan tegen de regionale overheden omdat zij hebben nagelaten de gezondheid van de burgers te beschermen tegen schadelijke niveaus van luchtvervuiling.

Lost nets, lines and hooks trap wildlife for years as they float in the ocean, sink to the bottom or are washed ashore

Earth For All is both an antidote to despair and a road map to a better future. Using powerful state-of-the-art computer modeling to explore policies likely to deliver the most good for the majority of people, a leading group of scientists and economists from around the world present five extraordinary turnarounds to achieve prosperity for all within planetary limits in a single generation.

Äerdchëff, le premier “earthship” (géonef) du Luxembourg, est sorti de terre à Redange. Un bâtiment quasiment autonome en énergie et en eau, en partie construit en utilisant certains types de déchets. Le gouvernement luxembourgeois veut en faire un projet pilote.

This Southern Ocean warming and its associated impacts are effectively irreversible on human time scales, because it takes millennia for heat trapped deep in the ocean to be released back into the atmosphere. This means changes happening now will be felt for generations to come – and those changes are only set to get worse, unless we can stop carbon dioxide emissions and achieve net zero.

Même si la sécheresse amène de nombreux cours d’eau européens à des niveaux record et endommage la biodiversité, la menace d’inondations catastrophiques à la suite d’une période de sécheresse se cache en arrière-plan.

Experts call for a new ‘Climate Endgame’ research agenda, and say far too little work has gone into understanding the mechanisms by which rising temperatures might pose a catastrophic risk to society and humanity.

Earth Overshoot Day is de dag waarop de vraag van de mensheid naar ecologische hulpbronnen dat wat de aarde in dat jaar kan aanleveren, overstijgt.
