Restitution du rapport de synthèse sur les "Terres rares" de l'Expertise Scientifique Collective (ESCo) menée par le CNRS (auquel j'ai pu participer en tant qu'auteur contributeur) On y parle de sobriété : ➡️ www.calameo.com/read/0080830...

La crédibilité se mesure en acte, pas en mots!

Nice paper by my former colleague @yannquilcaille.bsky.social: each of the 180 historical world’s largest oil, gas, coal, and cement producers are at least responsible for 16 heatwaves "that would have been virtually impossible in a preindustrial climate"

So proud of this collaboration led by @cssn.org 110 top experts from around the world 13 chapters on who is blocking or slowing action on climate change A quantum leap in our understanding of why society has failed to solve this Will be free online Oct 14 1/x global.oup.com/academic/pro...

Something I did not expect about the impact of Climate Change and Heatwaves: ➡️ it raises violence against women news.un.org/fr/story/202...

#IPCC's 2022 #ClimateReport shows heatwaves in Europe will become more frequent, more intense & will last longer. By 2050, about half of the European population may be exposed to high or very high risk of heat stress during summer. ➡️ bit.ly/IICpt13

Cities are hot today in Europe! Besides, there is also the "growth-vs-environment" hot topic at the urban scale you can discover by reading this nice perspective by @charlotteliotta.bsky.social & @profjeroenbergh.bsky.social

Exceptional year for @cired.bsky.social at the ongoing @eaere.bsky.social conference: - Best Doctoral Dissertation Award for @romainfillon.bsky.social - Award for Outstanding Publication for Arnaud Goussebaïle Congrats to both of them and to @celineguivarch.bsky.social, Romain's supervisor!

Quick calculation by my collegue Houssein Guimbard at @cepii-paris.bsky.social : average US tariffs are larger today than they were yesterday (=increase on China more than compensate decreases on other countries). For other countries tariff levels remain high (25% auto/steel/alu still implemented).

L’OFCE rejoint désormais Bluesky 🦋 pour partager l’actualité de ses chercheurs 🥳. De nouvelles publications à suivre très prochainement 📊 📉👀!

With global warming closing in on 1.5C, one aspect is clear: some countries' emissions have exceeded their fair share. To deal with this, we present the concept of carbon debt in a new paper in @pnas.org. Lead author @setupelz.bsky.social explains in a long thread 👇🧵

This is actually a really nice visualization tool to watch how the climate has evolved 🤩

Just finished this book by Christian Arnsperger! Interesting to think about economic fundamentals from an existentialist angle: how fear and denial of being finite beings are distributed throughout the economic system and perpetuate it.

Agreed! AR7 will need to be more representative of SSPs But not only: scenarios with increase GDP convergence between South and North are also welcomed

Climate Mitigation Scenarios becoming more accessible ➡️ A major scientific effort to envision future low-carbon worlds

Trump's trade war could cost 0.5% of global GDP (1.3% for the US and China). This reminds the IPCC SR15 report, in which additional energy-related investments to reach the 1.5°C climate were said to be an annual average of $830 billion - about 0.83% of current global GDP. It's a matter of choice

"In most scenarios, AI will likely worsen overall inequality [...] It is crucial for countries to establish comprehensive social safety nets and offer retraining programs for vulnerable workers" Says IMF bit.ly/4hCRnHh Should AI be taxed to finance labor market transition costs? Just wondering.

Nice perspective paper by @andrijevic.bsky.social Linking Gender inequalities and Climate change ➡️ Review on exposure, vulnerability, adaptative capacities of women, but also direct mitigation benefits and behavioral disparities ➡️ Nice proposition for an extension and inclusion in SSP narratives

Inequalities widening outrageously in favour of the top rich! Not only an economic issue, but also an ethical dilemma for what @cecileduflot.bsky.social calls the Billionocracy era @lemonde.fr

You had a hunch climate change impacts would increase economic inequalities? You were right! 1/10

Great article by @glenpeters.bsky.social Crossing 1.5°C global temperature increase is near -> we can still hope for other targets. A call to shift scenarios and modelling scientific research questions from "How to reach this target?" to "Which target can be reached under reasonable assumptions?"
