'Antarctic sea ice has again fallen to a near-record low as a new study shows
the system is undergoing a significant "structural change".
Scientists have been using satellite images over the past 45 years to track the
extent of sea ice on the fringe of the continent.
During that time, sea ice has fallen below 2 million square kilometres on four
occasions — 2022, 2023, 2024 and 2025 — according to the Australian Antarctic
Program Partnership (AAPP).
This year's data, captured on March 1, was the third-lowest annual daily
minimum on record, it said.
Will Hobbs, an AAPP sea ice researcher at the University of Tasmania, said the
recent repeated lows were part of a downward trend observed since about 2016.
"What's alarming about it is how we're not alarmed anymore, because this is now
the new normal," Dr Hobbs said.
"It's another summer with really low sea ice and that's not surprising to us
anymore, because we've seen it back-to-back.
"It's just really worrying that we're seeing this long-term structural
change."'
