Ice sheet expansion may have started 2,000 years ago, but we canceled that

New research indicates that the Barnes Ice Cap, a remnant of the Laurentide Ice Sheet, shows evidence of re-expansion beginning around 2,000 years ago. This suggests the onset of a new ice age that was underway until human-caused climate warming reversed the trend around 1960. The findings provide direct physical evidence from the ice cap's base temperature about these long-term climate cycles and the impact of recent anthropogenic warming.
