I wonder if the recent increase of ppm of (some) atmospheric greenhouse gases has an equilibrium-shifting effect back that would result in increased disturbances/mini tectonic movements because of pressure against the surface of the earth? Just curious, because it would be neat to know if there is such a link, or even if there is such a link and that e.g. fracking causes more earthquakes because of 'adjusting geological densities' or something like that.
