Global warming has been wreaking havoc over Glaciers in Greenland and Antarctica, however for millions, ice is disappearing nearer to home as lakes lose their winter cover.
In a study published in Nature Climate Change journal, researchers evaluated the impacts of rising temperatures on ice cover crosswise over 1.4 million lakes in the Northern Hemisphere. They found that, from Wisconsin to Japan, a huge number of lakes that used to remain frozen every winter have already observed a few years without ice, and that a massive loss of lake ice will happen within the years to come.
The disappearing ice will influence cold-water environments and be felt by a great many individuals who live close to the northern lakes.

"Ice cover goes acts as a temperature reset for a lake each winter," said Catherine O'Reilly, a geology professor at Illinois State University and a co-creator of the investigation.
Without winter ice, lakes start warming prior in the year. Hotter surface water expands the danger of lethal algal sprouts and diminishes oxygen levels in a lake, adding the stress on fish and different life forms. Water temperature likewise influences which angle species can flourish. Certain fish — like walleye, salmon and trout — rely upon cool, oxygen-rich waters and don't adjust well in warm conditions.
People depend on lake ice, as well. Icy lakes bolster social and monetary activities including ice skating, fishing and winter festivals. Ice roads across rivers and lakes likewise give wintertime lifelines to numerous remote zones, incorporating Native American communities in Northern Canada.
With temperatures hitting record lows in the midwest a week ago, it's imperative to comprehend that the loss of lake ice won't occur at the same time.
Actually, winters are truly variable. The situation would be such that one day we won’t be left with ice but in fact it will be an expanding recurrence of winters without ice. That will happen throughout the following decades."
Our grandchildren are not going to have similar encounters we did," Dr. O'Reilly included. They're simply not going to have these winters each year.
