Dans cet échange entre Vinz et Théo, un ingénieur en IA et co-président de l'ONG Data for Good, on explore l'impact écologique et social de l'intelligence artificielle. Théo Alves Da Costa analyse l'explosion des données et des algorithmes et met en lumière les défis liés à la croissance exponentielle de l'IA, notamment en matière de consommation énergétique et de perte de compétences. Ils discutent de l'optimisation continue de notre société par les GAFAM, des questions éthiques et écologiques autour de l'IA, et de l'importance de réguler l'usage de ces technologies pour éviter un futur où la machine prendrait trop de contrôle sur l'humain. Le tout est abordé avec un regard critique sur l'avenir et des propositions alternatives pour une IA plus responsable.

04/17/2024 - Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19 % until 2050 due to climate change, a new study published in “Nature” finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists at the Potsdam Institute for Climate Impact Research (PIK) assessed future impacts of changing climatic conditions on economic growth and their persistence.

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

Since the late 1990s, I’ve covered energy, beginning with the rise and fall of Enron — first as a magazine writer before becoming a columnist and editor. For more than 11 years, I’ve been a columnist for Forbes. My focus has shifted from the ‘old energy economy’ to the ‘green energy economy.’ My stories, which cover the globe, have appeared in, and have been cited by, dozens of publications and broadcasts. I’m also the editor-at-large for Environment+Energy Leader and the Coalition for Rainforest Nations, which represents 53 rainforest countries worldwide. My job is to research and write about these countries, helping them get to net zero to fulfill their Paris pledges. My features and my columns have won several national awards.

Potential external cost savings associated with the reduction of animal-sourced foods remain poorly understood. Here we combine life cycle assessment principles and monetarization factors to estimate the monetary worth of damage to human health and ecosystems caused by the environmental impacts of food production. We find that, globally, approximately US$2 of production-related external costs were embedded in every dollar of food expenditure in 2018—corresponding to US$14.0 trillion of externalities. A dietary shift away from animal-sourced foods could greatly reduce these ‘hidden’ costs, saving up to US$7.3 trillion worth of production-related health burden and ecosystem degradation while curbing carbon emissions. By comparing the health effects of dietary change from the consumption versus the production of food, we also show that omitting the latter means underestimating the benefits of more plant-based diets. Our analysis reveals the substantial potential of dietary change, particularly in high and upper-

The damage functions in the models, which relate GDP to temperature and sea-level rise, account for impacts on agriculture, forestry, fisheries, floods, road infrastructure, energy supply and demand, and labor productivity. Using this novel approach, the researchers estimate that the avoided damages are 1.5-3.9 times higher than the costs of climate mitigation. In other words, one euro invested in climate solutions saves the world about 1.5 to 4 euros in effects from climate change.

The modern agricultural production system relies heavily on the use of synthetic pesticides, but over the course of recent decades various concerns have been raised on the associated negative externalities touching a variety of dimensions, such as human health and the environment. Yet, the magnitude of those effects is still unclear and data availability is scattered and heterogenous across dimensions, regions, and time. The public sector is called upon to develop and implement strategies to face those externalities and their associated social costs. This study aims to provide an assessment of social costs of pesticides in France in the prospect of an integration to the public budget spending, helping public authorities to identify financial flows of public funding with an impact perspective, within a methodological framework based on the social norms at the core of the public system. The results show that the social costs attributable to synthetic pesticide use in France amounted to 372 million euros, of whi
