Marine cloud brightening, a geoengineering approach to cooling the surface of the Earth by increasing the reflectivity of marine clouds, may be more difficult to execute than anticipated, according to a new NOAA study.
A new, fine-scale modeling approach developed by NOAA and CIRES scientists now projects that there will still be enough high-elevation snow by the middle of the 21st Century to support - according to federal biologists - the denning habits of one iconic North American mountain-dweller, the wolverine.
