UN sustainable energy initiative could put world on a path to climate targets

A new study shows that reaching the 3 energy-related objectives proposed by the United Nations in their Sustainable Energy for All (SE4All) initiative, launched in 2011, would reduce emissions of greenhouse gases that contribute to climate change and, in combination with other measures, could help keep global temperature rise from exceeding the internationally agreed target level of 2 C.

Solar geoengineering by coalition

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.
