What does 10 TRILLION gallons of water even equate to?

I get so tired of seeing this constant GW being blamed on the people in the USA and Canada when it's a total and complete LIE! Wake up people! GW and GC is a normal and recurring event on the planet earth just like ice ages. We live where it was once tropical and was under the ocean and then later was under 1-1/4 miles thick ice glacier that carved out and created the 5 VAST Great Lakes in the USA and is presently 600 feet above sea level and still rising and rebounding from the massive ice's weight. Talk about naturally occurring changes??? Where have all you nay-say'ers been all you lives? Come out from deep under that rock and smell the real fresh air! We have very clean air and water too! Get smart for once as you are aging day by day until...!
