Recent changes in ice dynamics across the globe

Sapna Sharma, Gesa Weshenmeyer, John Lenters, John Magnuson, Rudstam and others in GLEON.

This project is an update of the Magnuson et al. 2000 Science paper using data through 2019, including Oneida Lake and Cazenovia Lake.  Overall, the ice data shows faster declines in the number of ice days in the 2000s, which unfortunately supports the observations of an accelerating warming of our planet.  All lakes are not equal and part of this analysis is to compare trends across the globe. A data paper to support these analyses was published in 2022 in Scientific Data (Sharma et al. 2022).
