The larger trend of global warming we're experiencing now (or aren't experiencing) has occurred in similar degree 4 TIMES IN THE LAST 1000 years (pg 16). Periods of abrupt and severe global warming took place as long ago as 900 AD.
Global warming took place before humans had the capability to produce large amounts of greenhouse gases!
