| Stephen Salter (2012) |
Stephen Salter was a giant who persisted to dedicate his life to combating climate change, and he did so in many ways until the very end.
Stephen's work on wave energy led to Salter's Duck (1974), a device able to both generate energy and reduce wave strength. In 1977, Stephen built a multi-directional wave tank at the University of Edinburgh.
In 2011, Stephen looked at ways to capture methane released in the Arctic, such as by covering lakes and parts of seas by sheets to collect the methane (drawing below).
In the video below, by theedinburghreporter, Stephen Salter talks about marine cloud brightening.
Stephen Salter (2022): "A jolly small change in reflectivity of the clouds will be sending solar energy back out to space enough to balance what the excess is that's being retained here by greenhouse gases (4:26-4:41). Maybe 10 cubic meters of water a second as sub micron drops sprayed in the right place would offset all the damage we've done since pre-industrial times (5:15-5:24)."
Our hearts are saddened by this huge loss, and our thoughts are with Stephen's family and his many friends. Stephen's work will not be forgotten.

Stephen was perhaps best known for his work on marine cloud brightening, i.e. deploying vessels to spray salt particles into the air in an effort to reduce sea surface temperatures thus also reducing sea ice loss and reducing the strength of extreme weather events including storms and hurricanes. In the video below, Stephen discusses marine cloud brightening in a TEDx talk in 2016.
