Comment supprimer progressivement les subventions aux combustibles fossiles afin de soutenir la transition climatique ? Cette question est analysée dans une récente « spending review » consacrée aux subventions aux combustibles fossiles, élaborée par un groupe de travail inter-administration auquel notre Service a également participé. Le rapport propose une série d’options politiques visant à réduire progressivement ces subventions dommageables pour le climat et ainsi accélérer la transition vers une économie plus durable.

Food security (FS) remains a pressing issue at the global scale. Current literature about FS points to a plethora of causes of food insecurity, among which climate change and the loss of biodiversity are critical to all facets of food security. Building on this notion, we advocate for a comprehensive understanding of drivers of food security, thus contributing by examining climate change and biodiversity as drivers of food security. The interest in this subject stems not only from the scientific community, but also from practitioners and policymakers. However, holistic encapsulation of the relevant literature addressing this subject is currently lacking. This review systematically analyses and categorises the drivers of FS induced by climate change and biodiversity. Following the Systematic Literature Review approach, 342 peer-reviewed studies were selected and synthesised. Our findings identified 11 categories of climate change drivers and 9 categories of biodiversity drivers of FS. These drivers were found

A climate monster is growing right now in the Pacific Ocean, perhaps the most fearsome El Niño since before scientists even began modeling them. They now know the pattern quite well: A marine heat-wave in the Pacific Ocean scrambles global weather and produces in some places more intense droughts and in others more intense rainfall and flooding; disruptions to hurricane patterns and monsoon seasons, which can cause widespread crop failures; and much more punishing heat.

This year, ExxonKnews reported on Big Oil targeting its critics, pushing false solutions, and encouraging political allies to help the industry escape accountability.

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.

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.
