Georgi Guninski: Have high temperature crashes happened before? If so, is there an estimate for the period?

Peep the core samples, son. Randall Carlson quote re: 'Oxygen Isotopes in Greenland': "As [the Earth] began to cool off, the temerature oscillations began to increase in magnitude." "The climate change that took us from glacial to interglacial happened in less than five years." --- Refs: New ice core records show Greenland in sync with the rest of the globe: http://arstechnica.com/science/2014/09/new-ice-core-records-show-greenland-i...
