Evidence shows a continuing increase in the frequency and severity of global heatwaves1,2, raising concerns about the future impacts of climate change and the associated socioeconomic costs3,4. Here we develop a disaster footprint analytical framework by integrating climate, epidemiological and hybrid input–output and computable general equilibrium global trade models to estimate the midcentury socioeconomic impacts of heat stress. We consider health costs related to heat exposure, the value of heat-induced labour productivity loss and indirect losses due to economic disruptions cascading through supply chains. Here we show that the global annual incremental gross domestic product loss increases exponentially from 0.03 ± 0.01 (SSP 245)–0.05 ± 0.03 (SSP 585) percentage points during 2030–2040 to 0.05 ± 0.01–0.15 ± 0.04 percentage points during 2050–2060. By 2060, the expected global economic losses reach a total of 0.6–4.6% with losses attributed to health loss (37–45%), labour productivity loss (18–37%) and i
Parce qu’elles cherchent à atteindre une frugalité efficace, ces initiatives intéressent un public grandissant à l’heure des dérèglements environnementaux et de la raréfaction des ressources.
Machine learning is producing impressive results, and, for better or worse, researchers are now using it to address the climate crisis, writes Frederick Hewett.
Wind, water and solar energy is cheap, effective and green. We don’t need experimental or risky energy sources to save our planet
The world’s reliance on hi-tech capitalist solutions to the climate and ecological crises is perpetuating racism, the outgoing UN racism rapporteur has warned. Green solutions including electric cars, renewable energy and the rewilding of vast tracts of land are being implemented at the expense of racially and ethnically marginalised groups and Indigenous peoples, Tendayi Achiume told the Guardian in an interview.
Two of the UK’s leading hospitals have had to cancel operations, postpone appointments and divert seriously ill patients to other centres for the past three weeks after their computers crashed at the height of last month’s heatwave.
The federal effort could set the stage for more studies into the feasibility, benefits and risks of one of the more controversial means of combating climate change.
Agriculture has come a long way in the twenty-first century. From precision irrigation systems to face recognition in livestock to deploying drones for improved crop yield, emerging technologies are reinventing farm country. Whether it’s hyperspectral monitoring (scanning soils and plant health) or tracking cattle’s movement and health, computing advances are making new technologies – powered by data – readily accessible for agriculture. The revolution in agriculture is delivering savings along with improved productivity. It is also big business: precision agriculture is expected to grow to a $11.1 billion industry in the next five years.
Selon des recherches américaines publiées mercredi dans la revue scientifique Environmental Science & Technology, divers produits pour enfants - des vêtements aux housses de meubles et aux taies d'oreiller - contiennent des substances per- et polyfluoroalkylées (PFAS).
Metals will play a central role in successfully building Europe’s clean technology value chains and meeting the EU’s 2050 climate-neutrality goal. In the wake of supply disruptions from the COVID-19 pandemic and Russia's invasion of Ukraine, Europe’s lack of resilience for its growing metals needs has become a strategic concern. This study evaluates how Europe can fulfil its goal of “achieving resource security” and “reducing strategic dependencies” for its energy transition metals, through a demand, supply, and sustainability assessment of the EU Green Deal and its resource needs . It concludes that Europe has a window of opportunity to lay the foundation for a higher level of strate- gic autonomy and sustainability for its strategic metals through optimised recycling, domestic value chain investment, and more active global sourcing. But firm action is needed soon to avoid bottlenecks for several materials that risk being in global short supply at the end of this decade.
Au début des années 1970, le club de Rome1 s’interroge sur la pérennité de la croissance dans un mode fini. Il confie une étude au Massachusetts Institute of Technology (MIT). Une équipe de recherche, emmenée par Dennis Meadows2, conçoit une modélisation du système socio-économique humain et de ses interactions avec la planète : le modèle World3. En 1972 paraît The Limits to Growth (Les limites à la croissance). Ce rapport, qui montre que la croissance a des limites, et que sa poursuite au-delà conduirait à l’effondrement du système, fait grand bruit.
The war in Ukraine and surging oil prices are other factors that could prompt PBOC action when it announces its policy loan rates Tuesday, as the nation aims to achieve a growth target of 5.5% for the year. The Hong Kong and China stocks sold off Monday, led by losses in technology shares, due to risks from Beijing’s close relationship with Russia and regulatory concerns.
Il y a 50 ans jour pour jour paraissait Les limites à la croissance, un rapport scientifique qui fit l’effet d’une bombe. Cette étude du Massachusetts institute of technology (MIT), supervisée par le professeur Dennis Meadows, concluait que la poursuite de la croissance économique nous mènerait inévitablement à dépasser les limites planétaires, provoquant un effondrement de la population humaine. Devenu une référence, ce document a pourtant été ignoré pendant plusieurs décennies. Alors qu’une nouvelle édition paraît aujourd’hui chez Rue de l’échiquier – quelques jours seulement après la sortie à bas-bruit du dernier rapport du Giec – Dennis Meadows s’exprime au sujet de l’actualité brûlante de son étude et confie son espoir pour le futur.
En mars 1972, il y a cinquante ans, une équipe de quatre jeunes chercheurs du Massachussetts Institute of Technology publie un rapport qui fera l’effet d’une bombe dans le monde occidental. Grâce à un ordinateur très puissant pour l’époque, ils ont essayé de comprendre ce qu’il se passerait sur la planète si le nombre d’êtres humains continuaient d’augmenter et si la croissance économique se poursuivait sur le même rythme.
We submit that the safe operating space of the planetary boundary of novel entities is exceeded since annual production and releases are increasing at a pace that outstrips the global capacity for assessment and monitoring. The novel entities boundary in the planetary boundaries framework refers to entities that are novel in a geological sense and that could have large-scale impacts that threaten the integrity of Earth system processes. We review the scientific literature relevant to quantifying the boundary for novel entities and highlight plastic pollution as a particular aspect of high concern. An impact pathway from production of novel entities to impacts on Earth system processes is presented.
Des sommets aux profondeurs. Après les microplastiques découverts mardi sur le Pic du Midi, dans les Pyrénées, voilà ces minuscules particules détectées dans nos selles. Et particulièrement lorsque l’on est atteint de troubles intestinaux. Comme le révèle le Guardian, une étude publiée dans la revue Environmental Science & Technology montre que les personnes atteintes d’une maladie inflammatoire de l’intestin (MII) présentent 50% de microplastiques en plus dans leurs selles.
The fundamental assumption underlying these beliefs is that economic growth can be “decoupled” from resource and ecological demands and impacts. That is, it is claimed that the rate of production and consumption can continue to increase while the resources needed to do this can be reduced to sustainable levels, along with the environmental damage it causes. It is disturbing that this tech-fix faith persists despite the mountain of evidence that it is wrong.
Al Gore shares examples of extreme climate events (think: fires, floods and atmospheric tsunamis), identifies the man-made systems holding us back from progress and invites us all to join the movement for climate justice: "the biggest emergent social movement in all of history," as he puts it. An unmissable tour de force on the current state of the crisis -- and the transformations that will make it possible to find a way out of it.
From turning CO2 into rock to capturing the breath of office workers, a growing number of companies think the answer is yes
The recent spike in natural gas prices has closed many plants that make fertiliser in the UK – sending a shockwave through lots of other industries.
Saint Graal rêvé, car promesse d’énergie propre « infinie », la fusion a peut-être franchi un cap le week-end dernier, au sein du Massachussetts Institute of Technology. Des chercheurs ont testé un nouveau type d’aimant pour confiner le plasma en fusion et produire plus d’énergie que consommée.
Operators say the Orca plant can suck 4,000 tonnes of CO2 out of the air every year and inject it deep into the ground to be mineralised
The industry has been pushing through policies devoting billions of dollars to the technology, and much more is likely to come with legislation pending before Congress.
A group of leading international researchers have issued a stark new warning to governments that relying on technology alone will not be enough to address the growing climate emergency, saying that presumptions that economic growth can continue unchecked should be challenged.
Behind the headlines about billionaire jaunts into space, there's a deeper motivation – the belief that spreading into the cosmos will save humanity's future. How did this idea emerge?
New research suggests social transformations that prompt “degrowth” could cut humanity’s climate footprint in time to meet the Paris climate agreement target.
Dennis Meadows: The notion that there is some kind of fairly attractive sustainable society ahead of us if we can only find it is now a fantasy. The global population, its use of materials, its generation of wastes has grown so far above the sustainable capacity of the planet that there is nothing ahead [of the kind] that the sustainable utopia people are talking about.
CCS - Carbon Capture and Storage: A research brief published by the Institute for Energy Economics and Financial Analysis (IEEFA) concludes that the abrupt recent shutdown of the Petra Nova coal-fired carbon capture plant in Texas should be seen as a strong signal for investors to avoid such projects.
Only 17.4 per cent of 2019’s e-waste was collected and recycled. This means that gold, silver, copper, platinum, and other high-value, recoverable materials conservatively valued at US $57 billion — a sum greater than the Gross Domestic Product of most countries — were mostly dumped or burned rather than being collected for treatment and reuse.
