A local ice fisherman says warmer temperatures in the fall make it harder to ice fish come winter time. Captain J.J. Malvitz is a professional ice fishing guide in Door and Kewaunee Counties. The success of his business, J.J.'s Guide Service, depends on how much Lake Michigan and other lakes freeze over. If temperatures are colder over the course of the fall, that makes it easier for the lakes to freeze up safely for ice anglers. 

Malvitz has not noticed temperatures being higher consistently but will fluctuate from year to year. He is not sure about the effects of climate change. But higher temperatures would be bad for his business and other ice anglers in the area.
