Cloud brightening hits a salty snag
The proposal known as solar radiation management is complicated. It just got moreso. Released Wednesday: Fossum, K.N., Ovadnevaite, J., Ceburnis, D. et al. “Sea-spray regulates sulfate cloud droplet activation over oceans“, Climate and Atmospheric Science, 3(14): (2020). https://doi.org/10.1038/s41612-020-0116-2 [open access] … Continue reading

A proposal: Challenge for the Green New Deal
