BOULDER, COLORADO — Arctic sea ice has reached its lowest recorded winter level, according to new data from the National Snow and Ice Data Center, adding to concerns about long-term climate trends.
Scientists said the seasonal maximum ice extent remains preliminary but warned the low level could accelerate melting during the upcoming spring and summer. Researcher Walt Meier noted that while a single year is not definitive, the continued decline since 1979 reflects significant changes in Arctic conditions.
Sea ice plays a critical role in regulating global temperatures by reflecting sunlight. As ice declines, more heat is absorbed by the ocean, contributing to warming and affecting ecosystems that depend on stable ice conditions…
