'"About half the world's population lives in the extratropical regions where storm tracks dominate weather," says Charles Gertler, a graduate student in MIT's Department of Earth, Atmospheric and Planetary Sciences (EAPS). "Our results show that solar geoengineering will not simply reverse climate change. Instead, it has the potential itself to induce novel changes in climate."'

Abatayo, Anna Lou; Bosetti, Valentina; Casari, Marco; Ghidoni, Riccardo; Tavoni, Massimo (2020): Solar geoengineering may lead to excessive cooling and high strategic uncertainty. In PNAS. DOI: 10.1073/pnas.1916637117.

"We study the governance of solar geoengineering using a laboratory experiment in which participants engage in a public good-or-bad game. Results confirm that too much geoengineering can occur, leading to considerable economic losses and increased inequality. The experiment also highlights unforeseen governance risks associated with such technologies."

"The world's climate scientists are charged with a difficult task: to create a crystal ball with which to skry a future that promises to be hotter than today. But exactly how much hotter depends on innumerable factors, both natural and human. Creating the crystal ball is thus a two-stage process. First, you have to build a simulacrum of how Earth’s climate works. Then, you try to perturb this simulacrum with plausible future human actions, to see what picture appears."

"Climate economist Dr. Gernot Wagner discusses how solar geoengineering can be a major solution to climate change. He considers Carbon taxes versus carbon taxes and talks about the issue of uncertainty as we find creative, market-based fixes for our warming planet."
