Why the new “Letter of Support for Solar Geoengineering Research” is misguided
The normalization of solar geoengineering as part of climate policy is progressing, with growing numbers of journal articles by geoengineering research advocates, editorial pushing by some science journals, and supportive actions by a few science networks in the United States. However, the opposition to solar geoengineering in global academia is growing as well, and more […]
Response to Overshoot Commission Report
The privately funded “Global Commission on Governing Risks from Climate Overshoot” released on 14 September 2023 a report that proposes a range of measures to reduce risks from climate “overshoot,” which the commission defines as exceeding the goal of limiting average global warming to 1.5oC. The report attempts to be comprehensive by acknowledging the need […]
The UK’s gamble on solar geoengineering is like using aspirin for cancer
Professor Raymond Pierrehumbert, Professor of Physics at the University of Oxford, and Professor Michael E. Mann, Director of the Penn Center for Science, Sustainability, and the Media at the University of Pennsylvania, critique the UK’s Advanced Research and Invention Agency (ARIA) funding for solar geoengineering field trials in a recent opinion piece. They describe the […]
ARIA’s ‘Exploring Climate Cooling’ Folly
On 7 May 2025, the UK Advanced Research and Invention Agency (ARIA) announced the list of projects to be funded under its £60 million solar geoengineering research initiative. Readers of this blog will already be familiar with solar geoengineering (also known as Solar Radiation Modification, or SRM for short), why it is a false response […]
Africa Is Not a Solar Geoengineering Test Site
In a recent Project Syndicate article, Chukwumerije Okereke, Professor of Global Governance at the University of Bristol and Co-Director of the Center for Climate and Development at Alex Ekwueme Federal University Ndufu-Alike, and Nnimmo Bassey, Director of the Health of Mother Earth Foundation, warn that experimenting with speculative solar geoengineering technologies on the African continent […]
