Paul R. Ehrlich will be remembered as a scientist whose books about population and threats to the environment shaped the idea of limited growth in the modern era.

We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the climate are no longer future threats but are here now. This unfolding emergency stems from failed foresight, political inaction, unsustainable economic systems, and misinformation. Almost every corner of the biosphere is reeling from intensifying heat, storms, floods, droughts, or fires. The window to prevent the worst outcomes is rapidly closing. In early 2025, the World Meteorological Organization reported that 2024 was the hottest year on record (WMO 2025a). This was likely hotter than the peak of the last interglacial, roughly 125,000 years ago (Gulev et al. 2021, Kaufman and McKay 2022). Rising levels of greenhouse gases remain the driving force behind this escalation. These recent developments emphasize the extreme insufficiency of global efforts to reduce greenhouse gas emissions and mark the beginning of a grim new chapter for life on Earth.

It is said that George W. Bush Jr. decided to invade Iraq in 2003 because he had read some papers on oil depletion by the Association for the Study of Peak Oil (ASPO). Of course, it may be just a legend, but I don’t see it as impossible, and perhaps not even improbable. Politicians make decisions on the basis of vague ideas, often on the spur of the moment, and in many cases making terrible mistakes. But they normally understand some of the critical elements that keep alive the system. For the US, the critical resource was, and still is, crude oil. So, it is possible that Bush thought that it was necessary to compensate for the decline of the US oil production by seizing the Iraqi resources. That didn’t necessarily imply to start a war, just like filling the tank of your car doesn’t imply shooting dead the service station operator. But that’s the way some people’s minds work.

C’est bientôt Noël et avec le nombre de politiciens bien sages qu’il y a sur notre planète, le Père-Noël n’a pas eu besoin de passer trop de temps dans le BlackFriday. Aura-t-il acheté le parfum pour enfant que Nabilla vient de lancer avec son fiston de 5 ans ? A elle seule, cette dernière phrase indique l’état actuel du monde. Une certitude : les démocraties ne sont pas faîtes pour survivre à la frénésie des réseaux sociaux et des médias.

Alors que l’Agence internationale de l’énergie s’apprête à publier son rapport annuel, mercredi, les pays producteurs qualifient de « fantasme » ses prévisions qui annoncent une diminution de la consommation de charbon, de pétrole et de gaz d’ici à 2030.

TotalEnergies va continuer à répondre à la demande de pétrole dans le monde, dont le pic interviendra "quelque part entre 2030 et 2040", tout en montant en cadence sur les autres sources d'énergie, le gaz et les renouvelables, a affirmé Patrick Pouyanné, son PDG dans un entretien aux Echos.
