Warming Halts 2,000-Year Growth of Arctic Barnes Ice Cap, Study Finds

Research suggests the Barnes Ice Cap in the Arctic began growing roughly 2,000 years ago, driven by cooler summer temperatures that favored ice buildup. That expansion has since been reversed by rising greenhouse gas emissions. The ice cap has shrunk significantly since the 1960s. Scientists stress that human-caused warming has disrupted the natural climate conditions that had supported renewed glacier growth.
