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.

本数据集为一份MathCad工作表，基于约翰·莱瑟姆（John Latham）提出的海洋云增亮方案，计算用于逆转海平面上升所需的喷雾船数量。本人对该计算结果感到意外，希望能对其中的论证逻辑与前提假设进行校核。任何用于评估可行性的初始工程计算，均需采用诸多精度存疑的近似假设，此类假设已以红色文本标注。若要使该方案具备可行的可能性，则必须提升这些假设的可信度。单一集中参数值应替换为数十年尺度的变量。蓝色文本为普通注释文本，黑色文本为可自动处理单位的动态代数表达式。本人可便捷地根据其他假设调整最终的喷雾船数量计算结果，期待获取各位的测算参数。核心要点如下：用于冷却海水的功率约为拯救冰盖所需功率的25倍，近乎2018年美国峰值发电装机容量的600倍，同时略高于全球总能源消耗量的35倍。
