"... in a world", reads much better in the original PLOS abstract 😄
For a 67m turbine, the highest regional wind generation change was for December-February under G4cdnc in a world but under G4 in a world for the same period. For a turbine, the highest change was an increase of for August-September under G4cdnc in a world and a decrease of −4.11% for December-January under G4 in a world. Marine Cloud Brightening-based SRM scenarios (G4cdnc and G4SeaSalt) produce the most consistent spatial increases in wind power resources and generation compared to Stratospheric Aerosol Injection (G4). > ---------- Forwarded message --------- > De : Geoengineering News <[email protected]> > Date: dim. 8 juin 2025 à 15:19 > Subject: [geo] The effects of solar radiation modification on solar and > wind resource and power generation in the Caribbean > To: geoengineering <[email protected]> > > > https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0325226 > > *Authors* > Matthew St. Michael Williams,Leonardo A.
