“...contains enough ice to contribute more than 2 feet to sea level rise...”
Maybe >2”, but I doubt 2ft, worldwide.
Smells like AGW BS to me.

It more like a drop in a bucket. The oceans of the world are approximately 140 million square miles. The size of Florida is approximately 65,755 square miles.
