49 feet? Over the whole jillion square miles of the seas surfaces? Pity the person who believes this stuff.
360 million square kilometers is the coverage of the oceans, X 49 feet in meters which is 15 meters...
360,000,000,000 Meters square * 15 meters = 5,400,000,000,000
5 trillion, 400 billion CUBIC meters of extra water....
is needed....
An ice shelf is already in the water...
These alarmists are NUTS!
Not only that, but there is more air in the ice than water ...
I think you're off by three orders of magnitude. One square kilometer is 1,000,000 square meters.
Or.. they think we're stupid.
By the way.. your math is right on.
I hate it when the ice in my glass melts and it overflows on the table.
