Solar geoengineering is a proposed approach to reduce the effects of climate change due to greenhouse gasses by deflecting some of the sun's incoming radiation. This type of proposed solution carries with it a number of uncertainties, however, including geopolitical questions about who would be in charge of the activity and its goals. New modeling work shows that if a powerful coalition ever decided to deploy a geoengineering system, they would have incentive to exclude other countries from participating in the decision-making process.
The robustness of food webs of Arctic and Antarctic ecosystems has been compared for the first time, revealing that global warming can affect the biodiversity of these ecosystems in different ways despite the similarities between them.
