Ice coverage for all the Great Lakes was at historical lows, with the coldest of the lakes — Lake Superior — having just 1% ice coverage as of Tuesday. The historical average is 40%.
The official start of spring on Tuesday highlighted an issue over the winter that will likely have environmental ramifications throughout the spring, summer and fall.
So, just how drastic has the change in ice coverage been in the past 10 years? The images below show that.Now, contrast that to a satellite image taken by the NOAA last month, nearly 10 years later.

Planetary scientists use physics and images of impact craters to gauge thickness of ice on EuropaSometimes planetary physics is like being in a snowball fight. Most people, if handed an already-formed snowball, can use their experience and the feel of the ball to guess what kind of snow it is composed of: packable and fluffy, or wet and icy.
