Abstract

Lakes and rivers covered by seasonal ice are extensively used by people. Although ice cover duration has been declining over the past 150 years for Northern Hemisphere lakes and rivers, we still know relatively little about how inland ice loss directly affects humans. In this presentation, the cultural ecosystem services that are supported by lake and river ice will be synthesized. Empirical examples that give quantitative evidence for a winter warming effect on a wide range of cultural ecosystem services will also be provided. In particular, in recent decades, warmer temperatures delayed the opening date of winter ice roads and led to cancellations of religious celebrations, skating races, and winter ice fishing tournaments.
