Arctic Sea Ice Flows South: Northwest Passage Navigation Season Shortens, Safety Risks IncreaseIn recent years, the accelerating melting of Arctic sea ice due to global climate change has not only raised concerns about rising sea levels and ecological changes but also brought new challenges to the safety of navigation in the Northwest Passage. A new study has found that from 2007 to 2021, the amount of thick sea ice flowing south from the Arctic Ocean has increased, resulting in a shorter ice-free navigation season in some parts of the Northwest Passage and increased risks to navigation safety...
