Les projets de croissance des aéroports européens, dont Brussels Airport et Brussels South Charleroi Airport (BSCA), sont incompatibles avec les objectifs climatiques européens, estime une étude de l'ONG Transport & Environment (T&E).
Global energy and materials are essential to the functioning of the economy and have significant implications for macroeconomics and the environment. At the same time, the world is not on track to meet Paris Agreement goals. This paper documents two stylized facts that connect these observations. First, the world economy is characterized by large embedded emissions and materials: different energies and materials are deeply entwined and interdependent. This has historically led to additive – rather than substitution – dynamics in energy and materials on a global scale. Second, historically there has been a strong positive correlation between efficiency in resource use and total resource use at a global scale. We synthesize these observations by introducing the Generalized Jevons Paradox (GJP). We argue that the GJP reflects the direct and indirect energy/material demand effects of long-term energy and material interdependencies, themselves shaped by market and geoeconomic power, trade arrangements, and financi
Le riz nourrit plus de la moitié de l’humanité depuis 9 000 ans. Mais selon une étude publiée dans Communications Earth & Environment, le réchauffement climatique progresse désormais 5 000 fois plus vite que la capacité d’adaptation de cette plante. Les régions rizicoles atteignent des températures jamais enregistrées dans toute l’histoire de cette culture — et le milliard de personnes qui en dépendent directement commence à manquer de temps.
La construction d'un datacenter en Utah a entrainé une opposition farouche des habitants. La course à l'IA repose la question de l'équilibre entre technologie et ressources limitées en eau, en terres arables et terres rares, en électricité. De nombreux datacenter vont utiliser des énergies fossiles.
L’ONG Transport & Environment calcule que la demande pour ces carburants produits à partir de ressources agricoles pourrait bondir de 30 % en 2026 et de 70 % d’ici à 2030.
Patrick Pester is the trending news writer at Live Science. His work has appeared on other science websites, such as BBC Science Focus and Scientific American. Patrick retrained as a journalist after spending his early career working in zoos and wildlife conservation. He was awarded the Master's Excellence Scholarship to study at Cardiff University where he completed a master's degree in international journalism. He also has a second master's degree in biodiversity, evolution and conservation in action from Middlesex University London. When he isn't writing news, Patrick investigates the sale of human remains.
Climate change is causing measurable harm globally1,2. Political and legal efforts seek to link these damages with specific emissions, including in discussions of loss and damage (L&D)3,4; however, no quantitative definition of L&D exists5,6, nor is there a framework to link past and future emissions from specific sources to monetized, location-specific damages. Here we develop such a framework, which is integrated with recent efforts to estimate the social cost of carbon7. Using empirical estimates of the non-linear relationship between temperature and aggregate economic output, we show that future damages from past emissions—one component of L&D—are at least an order of magnitude larger than historical damages from the same emissions. For instance, one tonne of CO2 emitted in 1990 caused US$180 in discounted global damages by 2020 ($40–530) and will cause an additional $1,840 through 2100 ($500–5,700). Thus, settling debts for past damages will not settle debts for past emissions. In other illustrative esti
Most research on “forever chemicals” focuses on how best to remove them from the environment. But solutions to tricky problems often emerge from the most unexpected of places—as demonstrated by a new study that instead redirects the pollutants into becoming tools for extracting precious lithium. In a recent Nature Water study, a team led by Rice University researchers describes a novel way to use spent perfluoroalkyl and polyfluoroalkyl substances, or PFAS, to recover lithium from high-salinity brine pools. The team tapped into the fluorine content inside PFAS leftovers, using it to attract lithium from briny water. Remarkably, the team was able to collect lithium fluoride at 99% purity and confirmed that the sample was pure enough to boost the stability and performance of lithium-ion batteries.
