If 1996 was almost 100 percent iced over, how can 1979's level of 94.7 percent be "the most on record."

Sure is quiet in climate change land. This is one cold winter and there is no reason that we couldn't have another.

Because davidgshaffe, it was Lake Superior that was nearly 100% iced over in 1996, but in 1979 it was ALL the Great Lakes that were iced over at 94.7%.

Serious question: Is climate change uni-directional, or can temps only go up under this definition?

honeyboo: You present a good question. Since the earth is round, it heats unevenly. It also tilts give or take about 22 degrees. Because of both factors, it creates winds. Depending on how much of the earth is covered by frozen or unfrozen (water) is determined by the evaporation (more or less, depending on wind and sun or clouds). With that said, climates tend to be cyclical because it can years, decades and even centuries for a climate to adjust to those conditions. I hope that answers your question.

Hmm, close to an 18 year cycle? 1996+18=2014, 1996-18=1978... Weather cycles, who would have thought.

It's beautiful, as Mother Nature intended.

Honeyboo - it's an accelerated warming of the entire planet in general. Even though there's cold weather in much of the U.S. this year, the temp evens out when you factor in other areas of the world being warmer than normal. The problem many people have is differentiating between extreme weather (cold snaps or heat waves), and more long term change. Basically, one cold winter in one part of the world doesn't mean the entire planet is cooling.

I live in Duluth and drove down by the Lake yesterday and it was open water for as far as the eye could see. I don't really understand this report. I've seen more ice than this on the big lake before.
