The present trumps the future. The past kicks us in the arse
A very simple reality left in the footnotes of newspapers at the time, and then tabled to giant research papers and committees as this was the only consensus that was able to be reached by fossil fuel addicted committees. "lets plan to form a commission in a few years, to do a study in a few years and look at the results in a few years for re-evaluation".
What matters is the magnitude of the effect: how much difference does it make?
There will be no secondary effect of geothermal energy extraction even noticeable compared to the present unfolding global climate catastrophe. The latter is what deserves attention. Anything else is a petty distraction. Raising petty distractions from it is a fundamentally evil activity.
