The 511 billion barrels reported is nearly double Saudi Arabia’s proven reserves and more than ten times the North Sea’s output over the last 50 years.

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.

“We have failed to shift the narrative and we are still caught up in the same legal, economic and political systems,” said David Suzuki in an exclusive interview with iPolitics. “For me, what we’ve got to do now is hunker down.”

Comment visualiser concrètement l’évolution des températures depuis 1880 ? Comment rendre accessibles les données scientifiques de la NASA ? C’est ce qui m’a motivé à créer NASA GISTEMP Viewer, une application web qui permet de voir les données sur une sphère en 3D.

Application web interactive pour explorer les données climatiques de la NASA depuis 1880 à travers un globe 3D dynamique.

Ende August organisieren Klimaaktivisten das erste »Kollapscamp«, um solidarisch durch Krisen zu gehen

Le magazine The Atlantic vient de sortir un nouveau récit, qui raconte cette fois comment deux journalistes ont obtenu une interview de Donald Trump.- […] Il a notamment confirmé que son mandat actuel à la tête des États-Unis était différent du premier, et a expliqué - à sa manière - en quoi: "La première fois, j'avais deux choses à faire: diriger le pays et survivre, j'avais tous ces escrocs. La deuxième fois, je dirige le pays et le monde".

Olivier Hamant, chercheur en biologie et en biophysique, est invité chez Thinkerview. Cela donne l'interview la plus inspirante de la chaîne selon moi. Il y présente le concept de robustesse, l'outil qui permet de faire face à un monde fluctuant. Il répond toujours avec justesse et beaucoup d'humilité, quel plaisir d'avoir un intervenant de ce niveau. Je vous invite vraiment à regarder l'interview en entier, c'est une masterclass.

Donald trompe. Le journaliste Darius Rochebin a posé une question surréaliste sur le climat à l’eurodéputée d’extrême droite Marion Maréchal, dans une interview sur LCI début février. Un traitement médiatique qui entretient le flou entre les faits scientifiques et la désinformation climatique pure et dure.

Alors que le gouvernement Trump enchaîne les fermetures de sites web fédéraux, de nombreuses organisations non partisanes s’efforcent d’archiver les données scientifiques, concernant notamment la santé et le climat, avant qu’elles ne disparaissent pour toujours. Une tâche ardue, constate “MIT Technology Review”.

Emerging infectious diseases, biodiversity loss, and anthropogenic environmental change are interconnected crises with massive social and ecological costs. In this Review, we discuss how pathogens and parasites are responding to global change, and the implications for pandemic prevention and biodiversity conservation. Ecological and evolutionary principles help to explain why both pandemics and wildlife die-offs are becoming more common; why land-use change and biodiversity loss are often followed by an increase in zoonotic and vector-borne diseases; and why some species, such as bats, host so many emerging pathogens. To prevent the next pandemic, scientists should focus on monitoring and limiting the spread of a handful of high-risk viruses, especially at key interfaces such as farms and live-animal markets. But to address the much broader set of infectious disease risks associated with the Anthropocene, decision-makers will need to develop comprehensive strategies that include pathogen surveillance across s

Atrazine is an herbicide widely used on plantations worldwide. Experimental studies suggest that the herbicide impairs male reproductive function in mammals. This systematic review and meta-analysis aimed to evaluate the impact of atrazine exposure on the levels of hormones from the hypothalamic-pituitary-testicular axis using murine as the animal model. After an extensive literature search, we selected 25 articles for the systematic review.

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.

Cela va faire bientôt six mois que Paul Watson a été arrêté et enfermé dans une prison au Groenland, dans l'attente d'une possible extradition vers le Japon. Six longs mois pendant lesquels toute la rédaction de Vakita s'est mobilisée pour médiatiser le sort du capitaine, qui a fêté son 74e anniversaire le deux décembre dernier, loin des siens.

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
