The Great Lakes are experiencing their lowest ice cover in decades, with only 18% of the lakes' surface covered in ice as of February 2023. This is the lowest ice coverage since records began in 1973, and it is more than 20% below the average for this time of year.

The low ice cover is due to a combination of factors, including warmer temperatures, less snowfall, and increased wind speeds. The average temperature in the Great Lakes region was 3.5 degrees Fahrenheit (1.9 degrees Celsius) above average in January, and the region received less than half of its average snowfall. The increased wind speeds have also helped to break up the ice that does form.

The low ice cover has a number of implications for the region. It can lead to increased evaporation, which can in turn lead to droughts. It can also make it more difficult for fish to survive, as they rely on the ice to protect them from predators and the elements. The low ice cover can also make it more dangerous for people to travel on the lakes, as it can be difficult to see where the ice ends and the water begins.

The low ice cover is also likely to have a negative impact on the region's economy. The tourism industry relies heavily on the ice for activities such as ice fishing, snowmobiling, and skiing. The low ice cover is also making it more difficult for ships to navigate the lakes, which can lead to delays and increased costs for businesses.

The low ice cover on the Great Lakes is a sign of the changing climate. The region is warming faster than the rest of the world, and this is leading to a number of changes in the environment, including the loss of ice cover on the lakes. The low ice cover is a reminder of the need to take action to address climate change.

What it means for the rest of winter

The low ice cover on the Great Lakes is likely to have a number of implications for the rest of winter. It is likely to lead to more rain and less snow in the region, as the warmer temperatures will cause more of the precipitation to fall as rain. The low ice cover is also likely to make it more difficult for snow to accumulate on the ground, as the warmer temperatures will cause the snow to melt more quickly.

The low ice cover is also likely to lead to more flooding in the region, as the increased runoff from the melting snow and ice will put a strain on the region's drainage systems. The low ice cover is also likely to make it more difficult for people to travel on the lakes, as it can be difficult to see where the ice ends and the water begins.
