Civil society briefing on the Working Group II Report of the IPCC’s Sixth Assessment: Beyond the Limits. How Gambling on Overshoot is Pushing the Planet Beyond a Point of No Return

by the Germany-based Heinrich Böll Stiftung (HBF) and the U.S. Center for International Environmental Law (CIEL)

The joint HBF-CIEL briefing summarizes the IPCC’s latest findings on the risks of temperature overshoot and of strategies premised on the possibility of returning from such overshoot through the use of solar radiation modification (SRM) or technological carbon dioxide removal (CDR).

IPCC report – Climate Change 2022: Impacts, Adaptation and Vulnerability

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.

The Summary for Policymakers of the Working Group II contribution to the Sixth Assessment Report (AR6) as well as additional materials and information are available at https://www.ipcc.ch/report/ar6/wg2/

Video: Recording: Webinar: Negative emissions and net zero: how do technologies for carbon dioxide removal measure up? (CCUS Projects Network)

“The European Union is committed to keeping the average temperature rise to well below 2°C, preferably closer to 1.5°C, which according to the Intergovernmental Panel on Climate Change (IPCC) requires bringing global GHG emissions to net zero by 2050. The IPCC scenarios show that alongside implementing other climate mitigation policies it is essential to remove CO2 from the atmosphere, known as carbon dioxide removal (CDR) which includes negative emission technologies (NETs). Various options are being reviewed and discussed, including both nature-based solutions and CCS-based solutions. The most common CCS-related solutions identified are direct air carbon capture and storage (DACCS) and CCS on energy production from biomass (BECCS). This event will discuss policy mechanisms for the delivery of CDR, storage longevity and the role of offsetting, and present some real project examples and the potential range of biogenic sources that combined with CCS can enable CDR.”

Dunford, Eric; et al. (2021): Deploying Low Carbon Public Procurement to Accelerate Carbon Removal

Dunford, Eric; Niven, Robert; Neidl, Christopher (2021): Deploying Low Carbon Public Procurement to Accelerate Carbon Removal. In Front. Clim. 3. DOI: 10.3389/fclim.2021.686787.

“Carbon dioxide removal (CDR) will be required to keep global temperature rise below 2°C based on IPCC models. Greater adoption of carbon capture utilization and storage (CCUS) technologies will drive demand for CDR. Public procurement of low carbon materials is a powerful and under-utilized tool for accelerating the development and of CCUS through a targeted and well-regulated approach. The policy environment is nascent and presents significant barriers for scaling and guiding emerging technology solutions. The concrete sector has unique attributes that make it ideally suited for large-scale low-carbon public procurement strategies. This sector offers immediate opportunities to study the efficacy of a supportive policy and regulatory environment in driving the growth of CCUS solutions.”

Truthout: Chomsky and Pollin: We Can’t Rely on Private Sector for Necessary Climate Action

“In this exclusive interview for Truthout, Noam Chomsky, one of the world’s greatest scholars and leading activists, and Robert Pollin, a world-leading progressive economist, offer their own assessments of the IPCC report. Chomsky and Pollin are co-authors of Climate Crisis and the Global Green New Deal: The Political Economy of Saving the Planet (Verso, 2020).”

Yale Environment 360: In the New UN Climate Report, a Better Understanding of Solar Geoengineering

“The latest report from the UN Intergovernmental Panel on Climate Change offers not only a clearer view of the causes and consequences of global warming, but also a better understanding of some extreme and untested solutions to the climate crisis, including solar geoengineering — the process of modifying clouds or spraying tiny reflective particles into the upper atmosphere to block a portion of the sun’s light, thereby cooling the planet, Reuters reported.”

Beck, S.; Oomen, Jeroen (2021): Imagining the corridor of climate mitigation – What is at stake in IPCC’s politics of anticipation?

Beck, S.; Oomen, Jeroen (2021): Imagining the corridor of climate mitigation – What is at stake in IPCC’s politics of anticipation? In Environmental Science [&] Policy 123, pp. 169–178. DOI: 10.1016/j.envsci.2021.05.011.

“The article examines how the Intergovernmental Panel on Climate Change (IPCC) performs its self-proclaimed role as ‘mapmaker. We seek to contribute to the emerging literature on global environmental assessments (GEA) and climate politics by reconstructing how the IPCC imagines the corridor for climate mitigation.”

Keyßer, Lorenz T.; Lenzen, Manfred (2021): 1.5 °C degrowth scenarios suggest the need for new mitigation pathways

Keyßer, Lorenz T.; Lenzen, Manfred (2021): 1.5 °C degrowth scenarios suggest the need for new mitigation pathways. In Nat Comms 12 (1), p. 2676. DOI: 10.1038/s41467-021-22884-9.

“As a first step to address this gap, this paper compares 1.5  °C degrowth scenarios with IPCC archetype scenarios, using a simplified quantitative representation of the fuel-energy-emissions nexus. Here we find that the degrowth scenarios minimize many key risks for feasibility and sustainability compared to technology-driven pathways, such as the reliance on high energy-GDP decoupling, large-scale carbon dioxide removal and large-scale and high-speed renewable energy transformation.”
