The short answer is no, the long answer is no, but the really long answer is that everybody pretends that it's 100% safe but I guarantee nobody predicted global warming occurring when fossil fuels first started being used. There will be secondary effects, we just don't know what they are yet
People predicted global warming occurring when fossil fuels started being used.
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".
"Secondary effects" is meaningless put up against well-known global catastrophe. Everything has secondary effects. New shoes means your old shoes go unused. Eating now makes you crap later.
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.
No one can predict anything when they don't have access to the larger model. Assuming the real world corresponds to big models rather than the small models and understanding people usually have.
