ScienceIce sheet expansion may have begun 2,000 years ago—until humans reversed it
Physical evidence from the Barnes Ice Cap on Baffin Island indicates the Laurentide Ice Sheet reached its smallest extent about 3,600 years ago and began expanding again roughly 2,000 years ago. Researchers interpret that growth as the opening of the next glaciation, a trend reversed around 1960 by human-caused warming.
