It’s coming sooner than we realized, a CU researcher says (KUNC) David J Lubinski Tue, 12/10/2024 - 16:02 Categories: Research Tags: Jahn Alexandra Jahn speaks with KUNC's Erin O'Toole about her recent research to predict when the first ice-free day on the Arctic Ocean might occur. Jahn and her collaborator found that day could happen within the next 20 years – and possibly in as few as three years. An ice-free Arctic could significantly impact the ecosystem and Earth’s climate. window.location.href = `https://www.kunc.org/podcast/inthenoco/2024-12-10/an-ice-free-day-on-the-arctic-ocean-its-coming-sooner-than-we-realized-a-cu-researcher-says`;

Moreover, sea ice volume was very low in the Arctic. Alexandra Jahn notes that human-caused emissions “are required to get an Arctic sea ice loss as large as observed”. window.location.href = `https://www.carbonbrief.org/antarctic-sea-ice-maximum-in-2024-is-second-lowest-on-record`;

In this article, they highlight five projects that are changing how researchers think about plastic and what happens after it is tossed away. One of these projects is a study led by Alexandra Jahn about how sea ice moves microplastics in polar regions. Working with her are colleagues from NCAR, U Washington, and WHOI.

The findings suggest that the first ice-free day in the Arctic could occur over 10 years earlier than previous projections. window.location.href = `/today/2024/03/05/arctic-could-become-ice-free-within-decade`;
