Dec. 16 (UPI) -- The National Oceanic and Atmospheric Administration unveiled Tuesday its annual Arctic Report Card painting a grim picture for the polar region as experts say winter's "whole concept" was reportedly being "redefined" amid its environmental breakdown.

NOAA reported that from October 2024 to September this year the Arctic experienced its hottest year in 125 years. It marked the tenth straight year of record warmth.

"Across these changing landscapes, sustained observations and strong research partnerships, including those led by communities and Indigenous organizations, remain essential for understanding and adaptation," NOAA officials warned in its report.

Ongoing global fossil fuel emissions have been causing the Arctic to warm four times faster than the rest of the planet, which has disrupted Earth's natural climate regulator.
