HERE'S an interesting lingering effect of the Ice Age: reduced gravity in northern Canada. Check out this excerpt from the CBC News article:
Moving to northern Canada won't make it any easier to fit into your old swimsuit, but it will help fool your bathroom scale into thinking you've lost a gram or two, thanks to a lower force of gravity in some regions.
That's according to researchers studying the impact of a massive glacial sheet that covered Canada during the last Ice Age. According to a study published Friday in the journal Science, the crushing weight of a massive glacier more than three kilometres thick caused rock beneath to compress and sink, displacing some of the semi-fluid mantle underneath the Earth's crust.
