Its interesting that the lake froze over implying that the water temp must have been low despite what that says. Global warming doesn't always mean warmer temperatures and drier weather, it means changes in weather patterns and an on average increase.Global warming has had a surprising impact on the Great Lakes region of the U.S. – more snow. A comparative study of snowfall records in and outside of the Great Lakes region indicated a significant increase in snowfall in the Great Lakes region since the 1930s but no such increase in non-Great Lakes areas.

Syracuse, NY, one of the snowiest cities in the U.S., experienced four of its largest snowfalls on record in the 1990s – the warmest decade in the 20th century, ...
“Recent increases in the water temperature of the Great Lakes are consistent with global warming,” said Burnett. “Such increases widen the gap between water temperature and air temperature – the ideal condition for snowfall.”
The research team compared snowfall records from fifteen weather stations within the Great Lakes region with ten stations at sites outside of the region. Records dating back to 1931 were available for eight of the lake-effect and six of the non-lake-effect areas. Records for the rest of the sample date back to 1950.
“We found a statistically significant increase in snowfall in the lake-effect region since 1931, but no such increase in the non-lake-effect area during the same period,” said Burnett. “This leads us to believe that recent increases in lake-effect snowfall are not the result of changes in regional weather disturbances.”

"In some glaciers, like the South Cascade Glacier in Washington ... the present rate of melting is greater than it ever has been for the last 5,000 years."
* Arctic temperatures during the late 20th century appear to have been the warmest in 400 years.
* Satellite data suggest that the extent of snow cover has declined by 10 percent since the late 1960s.
* Since the 1950s, the extent of northern hemisphere spring and summer sea-ice decreased by about 10 to 15 percent, and researchers have measured a decline of roughly 40 percent in the thickness of Arctic sea-ice during late summer and early autumn during the past several decades.
* Since the 1950s, Alaska has warmed by an average of 4 degrees Fahrenheit.
* Pine Island Glacier, part of the West Antarctic Ice Sheet, thinned by up to 1.6 meters (5.2 feet) per year between 1992 and 1999.
