“The last million years (a mere heartbeat on the geological time-scale) has been atypically cold, with extraordinarily large fluctuations in temperature. This period can be described as a series of 100,000-year-long cycles of dangerously cold ice ages (10C colder than today) and warm interglacials (where we are now). The interglacials are relatively short, usually a few thousand years, and we are already 12,000 years or so into this one. The record would suggest we might soon descend into another dangerously cold glaciation.”
It seems we should be pumping as much CO2 into the atmosphere as possible during this brief interglacial period, as earth is going to need a nice cosy blanket very soon.
Such a shame that humans are incapable of creating the massive CO2 quantities required to provide this warm blanket.
