But there\u2019s more going on than has been studied in just our region of the world.<\/p>\n\n\n\n<p><strong>Consequences of less ice on lakes<\/strong><\/p>\n\n\n\n<p>While there\u2019s much more to be studied, here\u2019s a brief summary of what this study has compiled from around the world:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The ways people are able to take advantage of iced-over lakes are being affected. <a href=\"https:\/\/www.mprnews.org\/story\/2023\/12\/20\/warm-weather-forces-cancellation-of-planned-minnesota-ice-festival\">Ice festivals<\/a> and cultural events such as <a href=\"https:\/\/www.twp-northfield.org\/newsdetail_T10_R125.php\">ice hockey<\/a> <a href=\"https:\/\/www.mlive.com\/sports\/2024\/02\/up-pond-hockey-tournament-forced-to-move-indoors-due-to-lack-of-ice.html\">tournaments<\/a>, <a href=\"https:\/\/windspeaker.com\/under-northern-sky-xavier-kataquapit\/ice-roads-are-melting\">ice roads<\/a> for transportation and ice bridge connections, for example Mackinac Island to St. Ignace by snowmobile, as well as the spiritual connections some people have with the ice are being disturbed.<\/li>\n\n\n\n<li>Ice fishing is not only part of some cultures, but a source of food for many people. Access to certain kinds of fish and even the nutritional quality of fish can be affected by lack of ice.<\/li>\n\n\n\n<li>Winters could become wetter and warmer (as reported <a href=\"https:\/\/www.michiganpublic.org\/environment-climate-change\/2024-08-29\/great-lakes-winter-trends-mean-warmer-and-wetter-storms\">here<\/a>) because of a lack of ice coverage. Open water contributes to lake-effect snow.<\/li>\n\n\n\n<li>Scientists suggest that longer ice cover, cooling lake water, lowers nitrous oxide emissions, a potent greenhouse gas.<\/li>\n\n\n\n<li>Lake ice creates unique ecosystem for native biodiversity (for example, some native species need ice protection for eggs to reproduce, such as whitefish).<\/li>\n\n\n\n<li>Without ice, there could be further declines in native organisms and increased chances for further non-native species invading lakes.<\/li>\n\n\n\n<li>Less ice could mean <a href=\"https:\/\/www.youtube.com\/watch?v=ow0UrBkhLJQ\">more algal blooms<\/a> that are linked to warmer temperatures which could lead to nutrient overloads. That could mean an increased amount of cyanobacteria appearing in lakes, which is a current trend.<\/li>\n<\/ul>\n\n\n\n<p><strong>More lake ice study needed<\/strong><\/p>\n\n\n\n<p>Dugan said one of the reasons we\u2019re only putting together some of this information now is that there are few researchers spending time studying ice-covered lakes.<\/p>\n\n\n\n<p>\u201cTraditionally, we get out on lake in the summer and study them really intensively. And there\u2019s been a pretty major awareness of really needing to get more data in the winter to be able to answer some of these questions (about ice cover).\u201d<\/p>\n\n\n\n<p>As the Great Lakes and the regional inland lakes continue to see less ice over the decades, Dugan said we will still see some significant ice some years.<\/p>\n\n\n\n<p>\u201cWe\u2019re in this climate zone, where we can have mild winters punctuated by these massive polar vortex events that bring really cold weather. And so, winter overall, it\u2019s warming, but it\u2019s also getting a lot more variable. And so we\u2019re going to live through some interesting winters that are going to be all over the place.\u201d<\/p>\n\n\n\n<p>She concluded we will still see some good lake ice years. However, it\u2019s going to be a lot more uncertain as climate disruption continues because of continued fossil fuel use.<\/p>\n\n\n\n<p><em>This article was originally published on Michigan Public and is re-posted here with permission:<\/em><\/p>\n\n\n\n<p><a href=\"https:\/\/www.michiganpublic.org\/environment-climate-change\/2024-10-14\/consequences-of-less-ice-on-lakes-due-to-climate-change\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.michiganpublic.org\/environment-climate-change\/2024-10-14\/consequences-of-less-ice-on-lakes-due-to-climate-change<\/a><\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>About the Author:<\/strong><\/p>\n\n\n\n<p><a href=\"https:\/\/www.michiganpublic.org\/people\/lester-graham\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Lester Graham<\/strong><\/a><\/p>\n\n\n\n<p>Lester Graham reports for The Environment Report.
