Ongoing Project: 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, supporting the accelerating warming of the planet.  All lakes are not equal and part of this analysis is to compare trends across the globe. A paper analyzing trends was published in 2021 in JGR Biogeosciences with contributions from CBFS.  Additional analyses of these data set are ongoing, as is a data paper that is in preparation.
