I put a disagree here, not because the Thwaites risk is not real, but because the risk is not imminent hence Curt's western Florida solar-powered project will probably long outlast his presently young life.
Once the Thwaites ice shelf collapses there still will not be catastrophic sea rise since the present melting is under the ice shelf. The catastrophe follows the shelf collapse over time as the land borne ice rapidly moves to the sea, so the dual effects of new fresh water in the Antarctic ocean and rise of ground level in Antartica do definitely produce catastrophe worldwide, with this handy mapping device showing the consequences:

It is worthwhile to note that the consequences of such and event would decimate most of the world's most consequential cities. from New York, Washington and Miami to Shanghai, London, the Netherlands, Bangladesh, Kolkata and so much more.
All the TSLA considerations disappear, as does the planet as humans have known it.
'Doomsday' is obviously not alliterative. The real questions are: one, is there anything that can be done to stop that; two, what about Greenland?; three, what about the arctic regions and permafrost melting?; four; how can mankind stop destruction and simultaneously resuscitate the health of our planet?
On a pessimistic day I am convinced Elon Musk may well be the only really influential person who understands we are destroying our planet. Thus on slight less pessimistic days I HODL TSLA and and some others. Surely those will endure well beyond my lifetime. I rather doubt my nephews and nieces will live so well, if they survive. My spouse and I are the only ones who live in edifices above that zone of rise, and our second home is well below the future water level.
Of course all this will not effect any material change in human behavior until the catastrophe strikes.
