Summary
Arctic sea ice has reached record lows for the fourth consecutive month, with the lowest maximum extent recorded at 14.4 million square kilometers on March 20, 2025, according to Copernicus. The Arctic is warming at a rate up to four times that of the rest of the planet, prompting increased military and commercial vessel activity, particularly from Russia, as some regions may become ice-free by the summer within a decade. This decline in sea ice could make northern sea routes economically viable for longer periods, raising strategic interest, especially regarding Greenland’s resources.
