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.
