@chrisnelder Ok, I take your point. I might have been influenced by my country, France, where ecological laws are rather being rolled out.

@chrisnelder To be precise, it is SSP2 basis that took hits recently. It corresponds to a respect of countries' pledges on GHG emissions, and in the recent years we got Trump election and USA out of Paris agreement, the Russian war on Ukraine, and now US and Israël's attack on Iran. These are quite significant events not going in the direction hypothetized by SSP2 ; meanwhile, plane transportation is at its highest.
If we regard SSP2-4.5 emissions, it does seems that up to ~2023 (little more recent data is available), we match that quite well (e.g. https://journals.sagepub.com/doi/10.1177/29768659241304854 figure 3), but the political and economic direction is concerning.

@chrisnelder So, if you want to convince anyone that we are on track for SSP2-4.5, you need to at least adress current level of emissions against the various pathways projections.
Also, because you have an irrelevant piece of information about me (being a mathematician) does not mean you should assume anything about my knowledge of the topic. I happen to have recently trained as an actuary and written a thesis about climate change.

@chrisnelder You seem to make a confusion and ignore both my points 0 and 1 (even though you mean to adress 1 later on, but you don't really: you continue speaking about our current position, and do not give much data about our direction). The confusion: pathways are not primarily about Global Warming Levels, but about a set of socio-economico-political hypotheses leading (through models) to CO2-equivalent emissions then leading (through models) to GWL.
Add 0 : you *cannot* distinguish between pathways in 2026 by looking at GWL, since their uncertainty intervals all overlap!

@chrisnelder I don't quite see what this has to do with me knowing mathematics, but ok.
0. Note that there is little difference in terms of global warming level between these pathways up until ~2030, if I remember correctly from my actuarial thesis.
1. I am not talking about the situation, but about the direction: policies on carbon reductions are being rolled out in some countries, goals are most of the time not met, etc.
2. The situation is not very bright either, that being said: recent years have been quite hot, and I saw several climate scientists wonder if we are in a short term anomaly or if we underestimated global warming.

@chrisnelder @ai6yr @Sustainable2050 @rahmstorf We can do better than SSP2-4.5, but the current direction is rather to do worse. Everyone, especially leaders, need to feel concerned now.

#ESR Imaginons une situation hypothétique où, dans une future formation de profs, dans une UE susceptible d'accueillir un bout de formation sur la transition écologique, un collègue très actif dans le climato-scepticisme se positionnerait pour enseigner.
Qu'est-ce qui pourrait/devrait être fait pour éviter qu'il serve sa propagande de marchand de doute aux futurs profs ?

@burgervege @jmessager J'ai eu l'impression d'une tentative de faire une description clinique, froide, qui ne prend pas parti pour permettre au spectateur ou spectatrice la plus grande liberté de jugement. Mais en ne montrant que le point de vue des collabos, en ne montrant jamais en parallèle ce qui se passe dans les rues de Paris, le film édulcore la réalité d'une façon insupportable, et j'ai regretté être allé le voir (ça m'apprendra à aller voir Dujardin).
