Finally, food for thought...

Nuclear bomb testing and nuclear power-plant disasters has created a new identifiable sediment boundary preserved in Holocene sediments worldwide. This boundary is now associated with a proposed new epoch of the Quaternary Period called the Anthropocene — when human activities became plausibly the dominant force causing changes to Earth's global physical environment.

The United States conducted surface nuclear testing at Bikini Atoll in the South Pacific. Testing took place between 1946 and 1958. During that time, 23 nuclear devices were detonated at seven test sites on the reef itself, on the sea, in the air and underwater. So far, 8 nations in 2016 have successfully tested nuclear weapons. Whereas the last atmospheric nuclear test was in 1980, underground testing has continued.

Another proposed epoch name, not yet adopted, is perhaps.... Weshouldhavecene.
