Let's wait to make a new geological period until we have built a Mars colony. Not that it matters to geology.

If When humans will tragically perish the natural biosphere and then restore it back with artificially engineered biological species, it will be very easy to distinguish Anthropozoic era creatures, too.

Just try to do carbon dating without taking into account the bikini atoll (and similar) tests.  The changes are measurable already, and piling up.

I imagine this type of thing will significantly change the way we look at nuclear power.  Until global warming smacked us with the obvious, "the solution to pollution is diffusion" was considered absolute.  Now we've realized that the Earth's entire atmosphere isn't big enough for some pollutants.  Nuclear power allows the pollutants to be concentrated and sequestered (and potentially moved off-planet, but I suspect that sooner or later someone will want the stuff).  I suspect there are other cases were pollutants can be concentrated instead of diffused, but that is the obvious one.
