Do you think that in your lifetime the ocean levels will rise more than 6"-8" ?

I think that would be pretty extreme, but I suppose if the "big melt" continues, it is certainly a possibility. Guess I'll miss Assateague Island...

Well according to Al Gore's movie: Since the navy has been measuring Ice thickness for subs in the Arctic since the start of the cold war (1950's) the ice has melted 40%. That's less than 60 years. If 40% more melts they say i will raise the sea level 30 some feet. That is very bad for anyplace near coastal. And remember the ice is melting at a much faster rate now. So yes late in our life time the maps will need to be changed if you believe the scientists. 6-8 inches no problem-yes

No. Unless there was some cataclysmic upheaval like the Hawaiian Islands suddenly rise and become a continent larger than Australia. The forces needed to create that much water or decrease the land mass enough are beyond the ability of mankind.

G'day Willievanillie,
The short answer is no.
Models referenced by the Intergovernmental Panel on Climate Change (IPCC) predict that global temperatures may increase by between 1.4 and 5.8 °C (2.5 to 10.5 °F) between 1990 and 2100. The uncertainty in this range results from both the difficulty of predicting the volume of future greenhouse gas emissions and uncertainty about climate sensitivity.
With increasing average global temperature, the water in the oceans expands in volume, and additional water enters them which had previously been locked up on land in glaciers and the polar ice caps. An increase of 1.5 to 4.5 °C is estimated to lead to an increase of 15 to 95 cm (IPCC 2001).
The sea level has risen more than 120 metres since the peak of the last ice age about 18,000 years ago. The bulk of that occurred before 6000 years ago. From 3000 years ago to the start of the 19th century, sea level was almost constant, rising at 0.1 to 0.2 mm/yr; since 1900, the level has risen at 1–2 mm/yr [25]; since 1992, satellite altimetry from TOPEX/Poseidon indicates a rate of about 3 mm/yr
Life expectancy for an Australian male is 80 years. I was born in 1962 which gives me until 2042. I don't expect sea levels to be much greater by then. Even by 2100, it won't rise by much more than a metre. There is a lot of scaremongering going on about this issue.
I have attached sources for further reading on the issue.
Regards

Not likely, sure there's problems w/global warming and whether we take action quick enough or not won't make that much diff in my lifetime. Now if I lived near the beach I'd be a little more cautious in my remarks. I still think we won't notice a big diff for several hundred more to a thousand or so years.

No. And I live 56 feet above sea level.

Not in my life time, but i do think in the next 100 years they will. thats if were still here on earth to see it.

because frozen water takes up more volume than liquid water, I would have to say not in my lifetime.

No. Global warming is a myth.
