Asked about the persistence of the Los Alamos lab's problems, former NNSA director Miller smiled and said her colleagues at the nuclear oversight agency sometimes told the following joke: If Washington sent all three of America's nuclear weapons labs an order to study how to «jump,» they would all respond differently.
It seems clear enough from evidence of the geologic past that before the earth started ringing like a bell every 120K years from glacial to interglacial with the former dominating the other 10:1 in
persistence, the Eocene optimum 50 million years ago the earth was ice - free, green from pole to pole, it was
about 11F warmer overall, with the most dramatic warming in the highest latitudes (right where you'd want it if you could
ask for it), and atmspheric CO2 was several times what it is today, which makes sense in light of much warmer global ocean not able to hold as much CO2.
