Once upon a time, way back in pre-history, these latitudes were covered by a vast rain forest, which was the habitat for dinosaurs. On the other hand, the Great Lakes were carved by glaciers during the ice ages. Is it possible that the climatic pendulum may now be swinging back toward a warmer Earth? Could it be that the increasing use of fossil fuels over the last 150 years may be speeding up that pendulum? Only time will tell, but if that is the case, the use of non-polluting sources of the energy that we all depend on to support our way of life must be increased.
