Probably a very long time from now. Water levels are lower today then they were 170 years ago.

Some experts are theorizing that global warming wont cause a water world scenario. Yes, the polar ice caps are melting, however at the rate they are melting, the water levels on the coasts may rise but only slightly. the big problem lies where as the ice caps melt, the fresh water ice and bergs start to dilute the salt water in the oceans. This would deviate and possibly stop the gulf stream ocean current, which right now is what is keeping northern europe (Great Britain, France, and Scandinavia) from looking like Northern Canada. They are on similar latitudes. The gulf stream brings the warmer waters from the caribbean and the equator up north. with that effect gone, the possibility exists to enter another ice age. just a theory

Sea levels are rising very slowly - just over half the rise is caused by thermal expansion of the seas and oceans, the remainder is the additional burden of meltwater being introduced by the melting of parts of the ice caps.
If every last bit of ice on the planet melted it would still fall far short of a Waterworld scenario.
How long before all the ice melts? Thousands of years, it would require massive warming before the deep interior of Antarctica started to melt.
How fast are sea levels rising now? The global average is currently 3.1mm (⅛ inch) a year, it's accelerating and by the end of the century rises of approx 750mm (30 inches) are likely.

If all the ice in the world melts, the oceans will rise another 263 feet, comparable to the amount they've already risen since the last ice age. The oceans may rise another 40 feet beyond that due to themal expansion. That's it---300 feet of ocean rise is the absolute maximum. There's plenty of land above that altitude.

about one hundred years on the speed of human inhabitants explosion. we are already eating 50% of the entire annual biomass production of our in worry-free words residing house. that does no longer go away a lot for something of existence does it. All this is going to take is a million extra p.c. for human beings to be eating better than 1/2. Mass extinctions have began already with bee's and amphibians and there are a sort of creatures on the endangered record. after we've destroyed the food chain our volume is up. it is the upshot of our activities and senseless 'pass forth and multiply' ideas-set. And till humanity is composed of its senses at present or there's a substantial calamity to wipe us out, there is not any wish in any respect. because human beings idiotically overlook about all warnings to their destruction. this is going to effect in mass starvation, ailment and shortage of existence. training Shaman... quantum physics rocks.

hmm? I don't believe their is enough water to submerge all the land... but you can say goodbye to all the current islands.. most of Florida, half of Texas and several major coastal cities... and that's just here in the US!
Lol, I've never watched Al Gore's movie.. but thanks for trying.
Look up the elevation above sea level of the middle of Texas... 30 inches would make MOST of Texas a bay (under water)
same with Florida
Same with most Islands.
Same with many major Coastal cities.

i think that the earth is just going through a natural phase just like the ice age e.t.c what happens, happens but i don't think all the land will be gone even if everything did melt

Obviously "pip" gets his information from Al Gore's movie. Actually the IPCC says that the MAXIMUM increase in the sea level will be 34 inches by the year 2100.

By the time that happens there probably won't be anyone left to worry about it. Too much fighting for ridiculous reasons.
