A map of the last ice area (red outline) defined by the World Wild Biological Fund. The map includes a part of the Queen Elizabeth Islands (QEI, red), the north of the Canadian Arctic Islands (LIA-N, green), and CAA-SOUTH (yellow). , CAA-S (orange) and Northern Buffin Bay (white). These are Qei-in Gates (Ballantyne Strait), Wilkins Strait, Prince Gustaf Adolf Sea (PRL), SVERDRUP CHANNEL (SV.), EUREKA EI-OUT GATES (Fitzwilliamiam STRAIT (Fitz.), Byam Martin Channel (byam M.), Penny Strait, Cardigan Strait and Hell Gate (Hell), Fram Strait, Jones Sound, Lancaster SEN GULF (Amund.), M’Clure Strait 。 TUVAIJUITTUQ Marine Protected Areas (LIA-N) has been hashed and is scattered with multiple years of sea ice in the Arctic and water poly polyphs.

The North Pole’s “Last Ice Area” (LIA) -an important habitat of Ice -dependent species disappears within 10 years since the Chuo Arctic Ocean has no ice in the summer. Research by MCGILL UNIVERSITY researchers using high resolution models has been found.
This study is published in Journal Communications Earth & Environment.
Earlier, the low -resolution model suggested that the LIA could last for decades from that point. The stability of this area is to provide a habitat suitable for ice -related and ice -concentrated species, such as polar beetles, Beluga, bow head whales, walnuts, ring seals, beards, and ivory turrets that are suitable for ice -enriched species. It is important to save ecology.
“These discoveries emphasize the urgency of reducing global warming to ensure stable predictions of the LIA and the Arctic’s habitat,” said the master of a scientific paper. One Madeleine Fol said.
In 2019, the Canadian government designated a part of the LIA located north of the Canadian Arctic Islands as a protected area for the Tuvaijuittuq Marine Corps. In August 2024, the provisional protection of the area was extended for up to five years, but the Canadian government cooperates with partners to consider long -term protection.
The Inuit Community is deeply invested in protecting the unique Ecosystem of LIA. Environmental organizations, including the World Wild Biological Funds, have long been exercising to protect the LIA as a whole to support the resilience of the Arctic Economy.
“Our survey was based on a high -resolution model that considers sea and ice transportation through the Arctic Islands of Canada,” said Bruno Tremburay, a professor of the Ministry of Air and Maritime Research, who co -led this research. I mentioned it. “These suggest that LIA may disappear much faster than before.”
These new simulations revealed that a considerable part of the remaining ice of LIA flows south on the island, enters warm water, melts rapidly, and may have a potential LIA sea ice for 10 years. It became. The quick flushing of the LIA, which passes through the islands of the Canadian Arctic Islands, is only possible when there is no ice without ice on the central ocean of the Arctic Ocean. Saving thick ice in LIA is essential for protection because it hinders transportation of sea ice through the islands.
