Barnes Ice Cap climate research

Overview

Researchers studying the Barnes Ice Cap on Baffin Island, Canada, have published findings in the journal Science suggesting that human-driven greenhouse gas emissions may have halted a natural progression toward a new ice age. Using radiocarbon dating on ancient organic matter, such as mosses and shrubs, scientists determined that the 6,000 square kilometer remnant of the Laurentide Ice Sheet had been steadily expanding for approximately 2,000 years after reaching a minimum size roughly 3,000 years ago.

The warming trend observed in the early 1960s marked a turning point that reversed this growth. Specifically, the expansion was halted around 1960 or 1961, a period that included one of the hottest summers of the 20th century. The study emphasizes that human-induced climate change has disrupted natural glacial cycles, noting that the Arctic is warming roughly three times faster than the global average.

In a related development, a report from the International Cryosphere Climate Initiative and the United Nations Environment Programme warns of irreversible damage to the global cryosphere if warming thresholds are breached. The report indicates that global temperatures must be brought below 1°C by 2150 to maintain polar ice stability, noting that the cryosphere is a highly sensitive element of the climate system.
