Barnes Ice Cap study suggests human emissions halted a new ice age

Barnes Ice Cap Laurentide Ice Sheet climate change glaciation radiocarbon dating

A study published in the journal Science suggests that human-driven greenhouse gas emissions may have interrupted the onset of a new glacial period. Researchers focused on the Barnes Ice Cap, a 6,000 square kilometer remnant of the Laurentide Ice Sheet located on Baffin Island in Canada’s Nunavut territory.

By using radiocarbon dating on ancient mosses and shrubs, scientists reconstructed the history of the ice margin. The data indicates that after reaching a minimum size approximately 3,000 years ago, the ice cap began a steady expansion around 2,000 years ago. This expansion continued for nearly twenty centuries until modern warming reversed the trend.

Researchers noted that the expansion was halted around 1960 or 1961, a period marked by significant warming. The summer of 1961 was recorded as one of the hottest of the 20th century. The study highlights how human-induced climate change has disrupted natural glacial cycles, noting that the Arctic is warming roughly three times faster than the global average.
