Salter S. 2020 Sea Level Rise and Ice Recovery

This is a MathCad worksheet which calculates the number of spray vessels needed to reverse the rise in
sea levels using John Latham's proposal for marine cloud brightening. I was surprised at the result and
would like the arguments and assumptions checked.
Any initial engineering calculation to assess feasibility has to make use of many approximate assumptions
with questionable accuracy. These are marked with red text. If there is any chance of a feasible outcome
it will be necessary to increase confidence in them. Single lumped numbers should be replaced by
multi-decade variables. Blue is plain text. Black is live algebra with automatic unit handling. I can
easily adjust the final spray vessel calculation for any other assumptions and would like to know your
values.
Key points are that the power to cool ocean water is about 25 times the power needed to save the ice and
nearly 600 times the peak electrical generating capacity of the United States in 2018 and just over 35
times total world energy use.
