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 […]

When Do We Know Enough to Say Stop?

There is a large and growing mountain of literature about solar geoengineering that clearly expresses the conclusion that an advertent, planetary-scale manipulation of the Earth’s reflectivity is a very risky and uncertain endeavor. Here on this website you can read about many of the risks and potential adverse side effects, which are legion. You can […]

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 […]
