Otto, Danny; et al. (2021): Exploring Narratives on Negative Emissions Technologies in the Post-Paris Era

Otto, Danny; Thoni, Terese; Wittstock, Felix; Beck, Silke (2021): Exploring Narratives on Negative Emissions Technologies in the Post-Paris Era. In Front. Clim. 3. DOI: 10.3389/fclim.2021.684135.

"Negative Emissions Technologies (NETs)—technologies that remove additional greenhouse gases (GHGs) from the atmosphere—are receiving greater political attention. They are introduced as a backstop method for achieving temperature targets. A focal point in the discussions on NETs are the emission and mitigation pathways assessed by the Intergovernmental Panel on Climate Change (IPCC). Drawing on perspectives from Science & Technology Studies (STS) and discourse analysis, the paper explores the emergence of narratives about NETs and reconstructs how the treatment of NETs within IPCC assessments became politicized terrain of configuration for essentially conflicting interests concerning long-term developments in the post-Paris regime."

The Hill: A realistic response to the climate wake-up call

"Leaders across the world raised the alarm in response to the latest assessment of climate change by the Intergovernmental Panel on Climate Change (IPCC). Christiana Figueres, the former executive secretary of the UN Framework Convention on Climate Change said, 'This is a massive wake-up call that is sounding yet another alarm bell.' Al Gore warned 'There is no time left to waste,' and UN Secretary-General Antonio Guterres said, 'A code red for humanity.'"

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)."

Bloomberg: With New Urgency, Climate Scientists Recommend Carbon Removal

"The latest scientific assessment from the United Nations Intergovernmental Panel on Climate Change generated plenty of grim headlines on Monday, but at least one of its most important findings went largely unremarked upon. Cutting emissions is paramount, they say—but in order to keep warming below catastrophic levels, we now must also find a way to take billions of tons of the carbon dioxide we’ve poured into the atmosphere back out."

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."

IPCC (2021): AR6 Climate Change 2021: The Physical Science Basis

IPCC (2021): AR6 Climate Change 2021: The Physical Science Basis.

"The Working Group I contribution to the Sixth Assessment Report addresses the most up-to-date physical understanding of the climate system and climate change, bringing together the latest advances in climate science, and combining multiple lines of evidence from paleoclimate, observations, process understanding, and global and regional climate simulations."

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."

Hansson, Anders; et al. (2021): Boundary Work and Interpretations in the IPCC Review Process of the Role of Bioenergy With Carbon Capture and Storage (BECCS) in Limiting Global Warming to 1.5°C

Hansson, Anders; Anshelm, Jonas; Fridahl, Mathias; Haikola, Simon (2021): Boundary Work and Interpretations in the IPCC Review Process of the Role of Bioenergy With Carbon Capture and Storage (BECCS) in Limiting Global Warming to 1.5°C. In Front. Clim. 3. DOI: 10.3389/fclim.2021.643224.

"This paper contributes to recent debates about the role of the IPCC, and its framing of BECCS, at the science-policy interface."
