  • Tip of the Iceberg: Polar Ice Loss Effects the Planet

    When the United States purchased Alaska from Russia, Americans considered the “frozen wasteland” to be a reckless, wasteful acquisition. What could ice possibly offer? 

    In fact, polar ice is a critical resource for the Earth. The summer and fall of 2020 marked the lowest sea ice extent ever recorded in the Arctic Ocean, and the Intergovernmental Panel on Climate Change (IPCC) says contemporary September sea ice extents are so low that they are unprecedented in at least 1,000 years. Moreover, collapses in the ice shelves of West Antarctica, Canada, and Greenland raised concerns in 2020. The immediate effects of climate change in the polar regions are merely the tip of the iceberg—ultimately, they have profound effects on climate and communities around the world.

    Truth, trust, and transparency are key aspects to sound and sustainable governance of the Arctic, said Ulf Sverdrup, Director of the Norwegian Institute of International Affairs. He was one of a panel of experts who spoke on Nov. 30 at “The Arctic in a Post-Election World,” the first event in a two-part series sponsored by the Wilson Center’s Polar Institute.

    “If you’re a sea ice person, MOSAiC is the kind of experiment that you just live for,” said Don Perovich, a Dartmouth College researcher with the Multidisciplinary drifting Observatory for the Study of Arctic Climate. “It’s the kind of experiment you dream about. It’s an opportunity to spend a whole year on the ice, just watching how a floe evolves over time.” He spoke at a recent event sponsored by IARPC Collaborations, an Interagency Arctic Research Policy Committee (IARPC) member space where scientists and others involved in Arctic research share knowledge and resources. The researchers on the expedition, said Perovich, aimed to collect data that would shed light on the causes and consequences of the evolving and diminished Arctic sea ice cover. MOSAiC’s mission was to facilitate a breakthrough in understanding the Arctic climate system and improve the world’s climate and weather forecasting models.
