Le changement est possible. Plaidoyer pour une recherche en accord avec les limites planétaires Open
Est-il possible de continuer la recherche sans mettre en péril l’habitabilité de la planète ? Peut-être plusieurs d’entre nous se sont-ils déjà posés cette question. Je n’ai pas la réponse, mais j’ai acquis avec mes travaux la conviction q…

How to reduce the carbon footprint of Earth and Space Science? Potential strategies based on a comprehensive greenhouse gas budget for five French labs Open
To maintain global warming below 1.5°C the last IPCC report indicates global greenhouse gas (GHG) emissions should be reduced by 45% and 80% before 2030 and 2050, respectively, reaching an average of 2tCO2e.pers-1.yr-1 on Earth. Recen…
