Widespread loss of safe lake ice access in response to a warming climate

Acknowledgments We would like to thank the Arctic Mobilities team, including Alison Cook, Jackie Dawson, Chris Derksen, Stephen Howell, and Lawrence Mudryk, for extensive discussions and critical feedback on this research. We would also like to thank Aman Basu for assistance with data processing. Finally, we thank the Academic Editor and two anonymous reviewers for their constructive comments and helpful feedback. The CESM2-LE simulations presented here have been conducted through a partnership between the Institute for Basic Sciences (IBS) Center for Climate Physics (ICCP) in South Korea and the Community Earth System Model (CESM) group at the National Center for Atmospheric Research (NCAR) in the United States, repre- senting a broad collaborative effort between scientists from both centers. The simulations were conducted on the IBS/ICCP supercomputer “Aleph”. Author Contributions Conceptualization: Joshua Culpepper, R. Iestyn Woolway, Sapna Sharma.
