This article examines the technocentric bias that characterizes climate mitigation literature, focusing on the reports of the IPCC's Working Group III. This bias stems from structural features of the scientific field that prioritizes innovation, leading to the overrepresentation of technological solutions in climate research. Funding mechanisms further reinforce this tendency by incentivizing collaboration with industrial R&D, creating a self-reinforcing loop in which scientific authority and industrial interests converge. The IPCC's institutional positioning—as a policy-relevant yet politically cautious body—amplifies this dynamic by favoring allegedly “cost-effective” technological pathways that lack practical feasibility.
Climate sensitivity is substantially higher than IPCC’s best estimate (3°C for doubled CO2), a conclusion we reach with greater than 99 percent confidence. We also show that global climate forcing by aerosols became stronger (increasingly negative) during 1970-2005, unlike IPCC’s best estimate of aerosol forcing. High confidence in these conclusions is based on a broad analysis approach. IPCC’s underestimates of climate sensitivity and aerosol cooling follow from their disproportionate emphasis on global climate modeling, an approach that will not yield timely, reliable, policy advice.

Mitigation of Climate Change - Working Group III contribution to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change
The IPCC is currently in its Sixth Assessment cycle, during which the IPCC will produce the Assessment reports of its three Working Groups, three Special Reports, a refinement to the methodology report and the Synthesis Report. The Synthesis Report will be the last of the AR6 products, due for release in March 2023.
INTERLAKEN, Switzerland, March 20, 2023 -- There are multiple, feasible and effective options to reduce greenhouse gas emissions and adapt to human-caused climate change, and they are available now, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report released today. ...

Contribution du Groupe de travail I au sixième Rapport d’évaluation du Groupe d’experts intergouvernemental sur l’évolution du climat - traduction officielle
Météo, climat et GIEC Quel que soit l’endroit où nous habitons, nous vivons tous avec la météo : comment les conditions de notre atmosphère évoluent au fil des minutes, des heures, des jours et des semaines. Nous vivons également tous avec le climat, c’est-à-dire, en un lieu donné, l’ensemble des caractéristiques météorologiques moyennes sur plusieurs décennies. On parle de changement climatique lorsque ces conditions moyennes commencent à se modifier, du fait de causes naturelles ou du fait des activités humaines. La hausse des températures, les variations des précipitations, l’intensification de phénomènes météorologiques extrêmes sont autant d’exemples de changements climatiques, parmi bien d’autres caractéristiques
L'unité de travail du Groupe I du GIEC/@IPCC_CH a produit un "Résumé tout public" clair et concis 🙏, je me suis permis d'en faire une traduction citoyenne. Pour les profs, les gnomes, les décideurs, les élus, chefs d'entreprise, le voisin, etc. Enjoy!😉 Yann Webb
En 2019, environ 15% des émissions de gaz à effet de serre d’origine humaine provenaient du secteur des transports. La croissance moyenne de ces émissions dues aux transports a été constante entre 2010 et 2019, d’environ 2% par an. En France, le poids des transports est de 30%
The Working Group III report provides an updated global assessment of climate change mitigation progress and pledges, and examines the sources of global emissions. It explains developments in emission reduction and mitigation efforts, assessing the impact of national climate pledges in relation to long-term emissions goals.

The IPCC has finalized the second part of the Sixth Assessment Report, Climate Change 2022: Impacts, Adaptation and Vulnerability, the Working Group II contribution to the Sixth Assessment Report. It was finalized on 27 February 2022 during the 12th Session of Working Group II and 55th Session of the IPCC. Read the report here
BERLIN, Feb 28 – Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. People and ecosystems least able to cope are being hardest hit, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report, released today.
The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.
