Enkele ophefmakende studies die piepkleine plasticdeeltjes vonden in ons bloed, hersenen en teelballen liggen onder vuur. Sommige resultaten zouden niet voldoende gecontroleerd zijn op vervuiling of soms zouden microplastics verward zijn met vetweefsel. Discussie is niet ongewoon, nuanceren Belgische plasticexperten: "Dit is nu eenmaal hoe wetenschap werkt."

A new groundbreaking German study proves that pesticides spread much further from the field than previously believed. A team of scientists led by Professor Dr. Carsten Brühl tested topsoil, vegetation, streams and puddles from 78 locations over a 180 km stretch, from remote areas in the UNESCO forests on the mountain ranges to the farmland in the Upper Rhine area. The research team detected a total of 63 pesticides. Almost all measurement sites were contaminated. Residues were found in 97% of the soil and vegetation samples, often in complex mixtures of several active ingredients. This cocktail of pesticides is especially problematic because interactions can occur and effects can be amplified. The worrying results are consistent with previous smaller-scale studies in the South Tirol area in Italy. Large scale and prolonged pesticide use is a major factor in the sharp decline in populations of insects and other organisms essential for farming, as highlighted in our biodiversity campaign. The researchers see pe

The U.S. military is canceling more than 90 studies, including some that U.S. Defense Secretary Pete Hegseth dismissed as climate change "crap." Military and intelligence officials have over the past decade identified potential security threats from climate change that include natural disasters in densely populated coastal areas and damage to American military bases worldwide.

Key UN reports published in last two days warn urgent and collective action needed – as oil firms report astronomical profits The climate crisis has reached a “really bleak moment”, one of the world’s leading climate scientists has said, after a slew of major reports laid bare how close the planet is to catastrophe.

When people talk about ways to slow climate change, they often mention trees, and for good reason. Forests take up a large amount of the planet-warming carbon dioxide that people put into the atmosphere when they burn fossil fuels. But will trees keep up that pace as global temperatures rise? With companies increasingly investing in forests as offsets, saying it cancels out their continuing greenhouse gas emissions, that’s a multibillion-dollar question.

L'Oxford Institute for Energy Studies (OIES) a consacré plusieurs publications aux impacts de la guerre en Ukraine sur les marchés énergétiques depuis le début de l'invasion russe(1). Dans la publication en anglais ci-après mise en ligne le 7 mars, Michael Meidan(2) décrit en autres les conséquences possibles du conflit pour la Chine à court et plus long terme et la position de Pékin, « dans une impasse d'un point de vue géopolitique » : c'est un partenaire politique proche de la Russie, comme l'attestent plusieurs accords importants conclus dans le secteur énergétique en février 2022 mais le pays ne souhaite pas s'exposer à des risques de sanctions occidentales.

Meer dan 99,9 procent van de wetenschappelijke artikels is het erover eens dat de huidige klimaatverandering voornamelijk wordt veroorzaakt door mensen. Dat blijkt uit een steekproef van maar liefst 88.125 klimaatstudies die door collega-wetenschappers getoetst werden op hun kwaliteit.

ome problems are so big, you can't really see them. Climate change is the perfect example. The basics are simple: the climate is heating up due to fossil fuel use. But the nitty gritty is so vast and complicated that our understanding of it is always evolving. Evolving so rapidly, in fact, that it's basically impossible for humans to keep up.
