Great Lakes Winter Ice Down 30 Percent Since 1973

So Halloween is over and it’s near that time of year again. Snow will soon be falling in northern Michigan, snow shovels a shoveling, and the Great Lakes will be freezing over. But to what extent of the lakes will be ice covered? Since Great Lakes ice record keeping began in 1973, ice coverage has declined by an average of 30 percent. Records also show that the lakes are icing over later in the winter yet still melting around the same time in the spring. Back in the 1970's Lake Superior used to typically nearly freeze over completely in the winter. Below is a graph from the National Snow and Ice center for the western half of the Great Lakes on Jan 29, 2012. Notice the large swaths of Lake Superior that were ice free [the white part, blue represents ice].

The climate change will continue to accelerate every year if we don’t act. We can’t pretend it isn't happening or its just natural and leave this problem for our children and grandchildren to fix. Insulate your home. Drive a hybrid instead of an SUV. Get a Geothermal Heat Pump. Throw some solar panels on your house or business. But above all demand change from the politicians who continue to do the bidding of the plutocrats that have an undue influence on our politics and continue to pump out denier propaganda.
