This SRM problem can be addressed with bettter geograpic accuracy from the bottom up, than the top down- the authors seem to have overlooked Kerry Emanuel's exmination of the parallel possibilities of altering hurrricane track SST's and hence storm intensity by modulation of sea surface a

[geo] Re: New paper of modelling SRM on coral reefs

As Tom Goreau of UNEP and other coral conservation biologists have pointed out, SRM for coral survival in the face of anthropogenic or natural SST changes is best carried out locally, not globally. There is no need for geoengineering mission creep. On Thursday, October 12, 2017 at 5:53:48 AM U

How do green roofs, which cool by evapotransportation ( rooftop lawns require water much as those on the ground do) compare in cooling efficiency with higher albedo white roofs combined with an equal volume of water spraying when the sun is high? On Saturday, November 11, 2017 at 12:16:10 AM
