there is an overall decrease in Great Lakes ice cover over the past 40 years, with a decrease in variability as well. This graph shows the downward trend in ice cover area (in square kilometers) since 1973.[2] The total loss in area was 71 percent for all of the Great Lakes. What are we learning [...]

A note about identifying climate change impacts
Many events are linked to climate change by virtue of fitting a long-term trend. For example, the record-breaking “once in one thousand years” rains that drove the recent Nashville flood is part of the long-term trend of increasing heavy precipitation events in the Southeastern United States that has been fully documented and firmly attributed to climate change. While one cannot say with certainly that event was "caused" by climate change, one can and should say it is linked to climate change.
