Hello Phil’s Dad,
If I’m guilty of anything, it’s too much brevity. I shouldn’t have covered the totality of global warming potential effects in one short sentence…bound to lead to confusion. Your explanation of how tsunamis have been cuased by techtonic plate shift is fine, but your statement “tsunamis have never been caused by climate change” indiactes premature closure of inquiry. I don’t think many would rationally deny the melting of polar ice when there are massive changes in glaciers, the effects of which are pronounced.

Techtonic plates are affected as a result of changes in isostasy/eustasy and post glacial rebound on glacial isostatic adjustment. This can have an effect on seismic activity(i.e.: volcanic activity, earthquakes and, yes…tsunamis). Granted all this is a worst case scenario, current thinking is that the impact takes place over a hundred years or more, but we can’t say with certainty, given the current rapid pace of deglaciation. We, hopefully, have time to change our energy infrastructure before we reach that point.
