“if not for global warming all of North America would still be covered by glaciers”…Not at all!Glaciers are caused by global warming, as water vapor is forced by thermal energy into far corners of the globe, there to become trapped as ice and extruded under gravitational force in huge flowing rivers of chilling fresh water resources.The cooling this creates stops the flow of vapor, thus creating glacial recession, desert encroachment and localized atmospheric heating for lack of fresh water resources.
