Major new paleoclimatology study shows global warming has upended 6,500 years of cooling
Over the past 150 years, global warming has more than undone the global cooling that occurred over the past six millennia, according to a major study published June 30 in Nature Research's Scientific Data, ''Holocene global mean surface temperature, a multi-method reconstruction approach.'' The findings show that the millennial-scale global cooling began approximately 6,500 years ago when the long-term average global temperature topped out at around 0.7°C warmer than the mid-19th century.
