Raise the sea level by 11 feet??? Preposterous! Do these clowns have any idea how large the sea area is, and how to do simple arithmetic?
Just the Atlantic, Pacific and Antarctic = ~913,000 cu. km. = ~213,000 cu. mi. = ~200 quadrillion (2 followed by 17 zeroes) gallons.
Add in the Arctic and Indian oceans plus Caribbean, South China and Mediterranean seas plus salt water bays and you’ve got a truly ludicrous number.
