A lot of scary noise has recently been generated about CO2 being high, with accompanying statements that we could warm to conditions not experienced since before the ice ages began 3-million years ago. Crap!Attached is the previous interglacial warm period, the Eemian, 130,000 years ago. Please, note that CO2 rose 800 to 1300 years after the temperature, then continued for 4000-years after temperature deteriorated back into glacial cold.
The logical conclusions one can draw are that 1) CO2 did NOT cause temperature to rise, and 2) did NOT prevent it from falling. It most probably won't again.
The previous interglacial warmth was about 12,000-years long; this one has lasted 10,500 years, unless one counts the Younger Dryas as part of this one--in which case, this one has run 13,000 years, and the cold is overdue.
