Study: Human-Driven Warming Reversed the Start of a New Ice Age

A Science study of Canada's Barnes Ice Cap finds a glaciation that began 2,000 years ago was stopped by fossil-fuel warming in the 1960s.

What to know

  • A Science study used the Barnes Ice Cap, the last remnant of the Laurentide Ice Sheet, as a proxy to track the onset of the next glaciation.
  • The ice cap began expanding about 2,000 years ago, which researchers say marks the start of a new ice age, but fossil-fuel-driven warming from the 1960s onward reversed that advance.
  • The findings challenge prior research suggesting the next ice age would not begin for thousands of years, reframing when glaciations actually 'start'.

    ScienceAlert details how warming cut the glaciation short

    Expanded coverage explains the dating methods (cosmogenic beryllium-10 and carbon-14) and reports that by the 1960s rising summer temperatures caused the growing Barnes Ice Cap, the shrunken remnant of the Laurentide Ice Sheet, to retreat again, halting the nascent ice age.

    “It was just getting started, everything was normal, the next glaciation was about to happen – and yet it stopped…”

  2. background

    Study finds Barnes Ice Cap advance signaled a new ice age — Using carbon dating of ancient vegetation and beryllium-10 dating of exposed rock, researchers reconstructed the Barnes Ice Cap's history and found it began expanding around 2,000 years ago, which they argue marks the start of the next glacial period.
