Hansen & Geden (2023): Knowledge Politics in the Context of International Climate Negotiations – The IPCC Synthesis Report will shape COP28 and the Global Stocktake

Gerrit Hansen & Oliver Geden IN: SWP Comment 2023/C 25, 09.05.2023, 8 p., doi:10.18449/2023C25

The IPCC reports, and in particular the respective Summary for Policy Makers (SPM), provide a scientific basis for negotiations under the United Nations Framework Convention on Climate Change (UNFCCC). They are a key reference in the global climate debate. The most recent Synthesis Report (SYR) is considered one of the most important sources of information for the first Global Stocktake under the Paris Agreement, which is to be concluded at the UNFCCC Conference of the Parties (COP28) in Dubai in December 2023. The knowledge politics surfacing in controversies that were visible during the report’s adoption reflect the conflicting interests that will shape the upcoming round of new emission reduction and financing pledges.


Prütz et al. (2023): Understanding the carbon dioxide removal range in 1.5 °C compatible and high overshoot pathways

Ruben Prütz, Jessica Strefler, Joeri Rogelj, Sabine Fuss IN: Environ. Res. Commun. 5 041005DOI 10.1088/2515-7620/accdba

The authors analyze the range in CDR volumes in AR6 WGIII pathways by exploring relationships between variables as potential driving forces, focusing on CDR in 2050 and scenario properties linked to reaching net-zero CO2. It is also shown how the relative and absolute contribution of CDR to total mitigation up until reaching net-zero CO2 substantially differs across scenarios.


Q&A: IPCC wraps up its most in-depth assessment of climate change

CarbonBrief, 23 March 2023 17:01

Carbon Brief’s team of journalists has delved through each page of the IPCC’s AR6 full synthesis report to produce a digestible summary of the key findings and graphics. „The synthesis report is the last in the IPCC’s sixth assessment cycle, which has involved 700 scientists in 91 countries. Overall, the full cycle of reports has taken eight years to complete. The report sets out in the clearest and most evidenced detail yet how humans are responsible for the 1.1C of temperature rise seen since the start of the industrial era. It also shows how the impacts of this level of warming are already deadly and disproportionately heaped upon the world’s most vulnerable people. The report notes that policies in place by the end of 2021 – the cut-off date for evidence cited in the assessment – would likely see temperatures exceed 1.5C this century and reach around 3.2C by 2100.“


What is the IPCC AR6 synthesis report and why does it matter?

by Fiona Harvey, on The, Sun 19 Mar 2023 11.00 GMT

„Summary report by world’s leading climate scientists sets out actions to stave off climate breakdown.[…] What should governments do? Reduce emissions sharply and give up fossil fuels, through investments in renewable energy and other low-carbon technologies, increase energy efficiency, rethink agriculture and restore forests and degraded natural landscapes. It may also be necessary to develop technologies that suck carbon dioxide from the air, called “direct air capture”, or explore other means of “climate repair”.“


Webinar: Carbon Removal at Scale: A Call to Action from the IPCC Report

Thu, March 23, 2023, 10 AM – 11:30 AM EDT by World Resources Institut

The high-level webinar features IPCC authors, government representatives and leading carbon removal experts to discuss how carbon removal is a critical tool in our toolbox to address the climate crisis. Speakers will examine what the latest IPCC report says about carbon removal, which approaches are progressing the fastest, who are the frontrunners in the carbon removal market, how to address equity concerns, and what investments governments and businesses need to make now to rapidly scale up CDR deployment over the next 10 years.


C2GLearn: How does the Working Group-II report of the IPCC 6th Assessment address CDR and SRM?

by C2G Carnegie Climate Governance Initiative

This C2GLearn webinar (ca. 1h) aims to provide expert overviews of how the Working Group II contribution to the Sixth Assessment report addresses Carbon Dioxide Removal (CDR) and Solar Radiation Modification (SRM)? Speakers’ presentations were pre-recorded and played to the webinar audience. Afterwards, the speakers participated in the live Q&A session and the audience was able to ask clarifying questions.
