""A worldwide conversion to white roofs," they found, could actually warm the Earth slightly due a complex domino effect. Although white surfaces are cooler, the increased sunlight they reflect back into the atmosphere by can increase absorption of light by dark pollutants such as black carbon, which increases heating. "
So by analogy, increased snow/ice cover would "actually warm the Earth slightly" ? I don't think so, but please clue me in. - Greg ________________________________________ From: geoengineering@googlegroups.com [geoengineering@googlegroups.com] On Behalf Of Stephen Salter [s.sal...@ed.ac.uk] Sent: Friday, October 28, 2011 4:22 AM To: geoengineering@googlegroups.com Subject: [geo] White roof snag Hi All See http://www.guardian.co.uk/environment/2011/oct/27/white-roofs-global-warming and Jacobson, M., & Ten Hoeve, J.
