As @IPCC_CH 56th session continues this week towards the approval of the WGIII's assessment report on mitigation, you surely have a question: how does the IPCC approve reports? #ClimateReport #AR6 Image
Well, it is all explained here: ipcc.ch/site/assets/up…
I’ll copy the points for you: Image

So, the role of the report authors in the approval process is to guarantee that the summary is consistent with the underlying chapters and is scientifically robust.
The role of governments delegations is to ensure that statements are clear, unambiguous and understandable for policy makers.
This approval process with governments is useful, it establishes a common scientific foundation that all endorse. Political negotiations, eg within the UNFCCC – UN Framework Convention on Climate Change, can build on this common understanding of the scientific foundations.
I cannot tell you the content of the discussions on-going right now, but you can follow @IISD_ENB for that. See for instance their report of WGII approval session: enb.iisd.org/55th-session-i…

So that you are not caught by surprise by the @IPCC_CH Synthesis Report next Monday, let’s get prepared looking at the conclusion from the reports it synthesizes.
Let’s talk about WGIII report today. #ClimateReport #AR6
The report is on mitigation of climate change, i.e. human intervention to reduce emissions or enhance the sinks of greenhouse gases.
The report synthesizes scientific knowledge on past emissions and future emission pathways, emission reduction options, climate change policies, their financing and the innovations they require.

Afin de ne pas être pris par surprise par le rapport de synthèse du GIEC lundi prochain, préparons-nous en regardant les conclusions des rapports qu'il synthétise. #ClimateReport #AR6
Aujourd’hui, parlons du rapport du groupe III.
Le rapport du groupe II du GIEC @IPCC_CH évalue les connaissances scientifiques sur les solutions et trajectoires d’atténuation, i.e. de réduction des émissions de gaz à effet de serre, dont l’accumulation dans notre atmosphère est la cause du changement climatique.
Le rapport synthétise les connaissances sur le bilan des émissions passées et les perspectives d’émissions futures, les options de réduction des émissions, les politiques de lutte contre le changement climatique, leur financement et les innovations qu’elles requièrent.
