OK let's math Mr glowie. 100% ice melt. About 1000 years in the future Ave water depth on earth is 2700m deep. Therefore a 2.7% further addition of water is an extra 73m increase in water levels. Except : -.7% locked as groundwater lakes etc. Already melted and physically unable to enter the ocean. This leaves 2% possible. Except 1.7% is already in the ocean as ice and won't raise Sealevels. So 1000 years with 100% melt. (not actually possible = 10m rise. Which explains why after 100 years of muh globalism scare mongering we haven't seen sea level rises. The ocean is basically already at max height. What is the greater threat is soil erosion and tectonics.
