Its about 200-250 feet. Now we just have to calculate the probability of all the ice melting.
I can't prove anything but my gut tells me there are bigger forces than us out there. Sea levels have been going up and down since time began. Nothing we do is gonna make any difference.

Islands are disappearing.
news.mongabay.com... Carteret Islands are almost invisible on a map of the South Pacific, but the horseshoe scattering of atolls is on the front-line of climate change, as rising sea levels and storm surges eat away at their existence.
For 20 years, the 2,000 islanders have fought a losing battle against the ocean, building sea walls and trying to plant mangroves. Each year, the waves surge in, destroying vegetable gardens, washing away homes and poisoning freshwater supplies.

Papua New Guinea's Carteret islanders are destined to become some of the world's first climate change refugees. Their islands are becoming uninhabitable, and may disappear below the waves.

I have a wee question for the agw pushers.
Suppose over the next few years the data does not show rising sea levels, and as some are suggesting that there is a period of global cooling.
What do you guys do ?
Global sea level rose by about 120 meters during the several millennia that followed the end of the last ice age (approximately 21,000 years ago), and stabilized between 3,000 and 2,000 years ago. Sea level indicators suggest that global sea level did not change significantly from then until the late 19th century when the instrumental record of sea level change shows evidence for an onset of sea level rise. Estimates for the 20th century show that global average sea level rose at a rate of about 1.7 millimeters per year. Satellite altimetry observations, available since the early 1990s, provide more accurate sea level data with nearly global coverage and indicate that since 1993 sea level has been rising at a rate of about 3 millimeters per year.
Antarctica and Greenland, the world's largest ice sheets, make up the vast majority of the Earth's ice. If these ice sheets melted entirely, sea level would rise by more than 70 meters.
