New research published by Filazzola et al in Geophysical Research Letters analyzed a global ice phenology dataset spanning 80 years and 122 lakes. They show that many of these lakes increasingly have ice-free winter and this is expected to become even more common in the future as winter air temperature warms with continued climate change. None of these lakes analyzed were in Alaska and we don't think ice-free lakes are common or will be common in the future here. But are there already lakes that you know of that show this behavior in some years?
