A crucial system of ocean currents may already be on course to collapse, according to a new report, with alarming implications for sea level rise and global weather — leading temperatures to plunge dramatically in some regions and rise in others. Using exceptionally complex and expensive computing systems, scientists found a new way to detect an early warning signal for the collapse of these currents, according to the study published Friday in the journal Science Advances. And as the planet warms, there are already indications it is heading in this direction.

Le charbon n'a jamais autant été utilisé qu'aujourd'hui. Ici, je me concentre sur les impacts environnementaux et sanitaires que provoquent l'utilisation du charbon.

Finance needs of developing countries now 10-18 times as big as international public finance flows Growing gap results from rising adaptation needs and faltering adaptation finance Failure to enhance adaptation has huge implications for losses and damages

Les économistes sous-estiment les impacts économiques du changement climatique, ce qui n’incite ni le secteur financier...

I'm an independent healthcare analyst with more than 24 years of experience analyzing healthcare and pharmaceuticals. Specifically, I analyze the value (costs and benefits) of biologics and pharmaceuticals, patient access to prescription drugs, the regulatory framework for drug development and reimbursement, and ethics with respect to the distribution of healthcare resources. I have approximately 110 publications in peer-reviewed journals, in addition to hundreds of articles in newspapers and periodicals. I have also presented my work at numerous trade, industry, and academic conferences. From 1999 to 2017 I was a research associate professor at the Tufts Center for the Study of Drug Development. Prior to my Tufts appointment, I was a post-doctoral fellow at the University of Pennsylvania, and I completed my PhD in economics at the University of Amsterdam. Before pursuing my PhD I was a management consultant at Accenture in The Hague, Netherlands. Currently, and for the past 6 years, I work on a freelance ba

As we mark 100 days until the COP28 UN climate summit, the urgency of addressing the climate crisis has never been more palpable. Global failures to mitigate emissions and adapt to the impacts continue to wreak havoc on the planet, and we’re seeing this in a range of ways. Unprecedented extreme weather events have occurred with frightening regularity in 2023. In March, over 500 people lost their lives when Cyclone Freddy struck Malawi. Last month, flooding in the Philippines caused by Typhoons Doksuri and Khanun displaced more than 300,000 people, and the recent wildfires that ravaged Hawaii – in part exacerbated by climate change – continue to make for distressing headlines. This list is likely to become even longer by the end of the year, when COP28 gets underway in the United Arab Emirates (UAE).

L'étude, menée par l'assureur Axa Climate, liste plusieurs conséquences de la crise climatique dans les prochaines décennies.

Le secteur des transports fait régulièrement l'objet de comparaisons, souvent orientées par les promoteurs de tel ou tel moyen, sur leur impact environnemental. Les uns se réclament parfois plusieurs fois plus vertueux que les autres, et réciproquement, à jeu d'arguments plus ou moins fondés, souvent focalisés sur l'aspect ou le poste sur lequel ils excellent.

The populist right has made hay with social tensions climate change is likely to exacerbate.

🧲Notre appétit pour les métaux est responsable de nombreux impacts environnementaux et sociaux. La baisse de teneur des gisements va démultiplier ces impacts alors que notre appétit est grandissant. Du coup, est-il possible de prévoir la fin de l’exploitation minière tout en assurant la résilience de nos économies ? 🎓 Pour nous éclairer sur ces questions j’ai le plaisir de discuter avec Judith Pigneur. Judith est docteure en Génie Industriel. Sa thèse a porté sur la mise au point d’une méthode intégrée d’analyse des impacts des filières de matières premières minérales. Elle est chargée de projet matériaux & sobriété au sein de l’association négaWatt et développe une feuille de route sur des trajectoires de consommation minerais métalliques plus sobres.
