Out now! Past Global Changes Magazine (30)2: “Sea ice in the polar regions”
Past Global Changes Magazine vol.30 no.2: "Sea ice in the polar regions" with a special section on "Early-career perspectives on ice-core science" is available to read.
Understanding past, present, and future changes in Arctic and Antarctic sea ice is crucial to understanding a wide range of interconnected impacts. This special issue contains articles describing novel proxies and reconstructions of sea ice at a range of timescales from both poles, highlighting some state-of-the-art knowledge in this field.
Sea ice in the polar regions guest editors: Matthew Chadwick, Karen E. Kohfeld, Amy Leventer, Anna Pieńkowski, Heike Zimmermann and Sarah Eggleston
Special section: Early-career perspectives on ice-core science guest editors: Jessica Badgeley, T.J. Fudge, Bess Koffman and Summer Rupper.
