I recently asked about moving from coastal regions due to rising sea levels. Some people think that sea levels will only rise by a few inches whereas I understand that it could be many metres. Has anyone any idea what is expected if say the ice on Greenland melts fully (Its melting faster by the year at present)

I love East Anglia - and if the caps melted it would all disappear- which I think is tragedy - I can't imagine 4 counties wiped from the UK map! Brummies will only have to travel 10 miles for a coastal holiday.

Even if it is only a few inches, its significant enough to change the coastal areas. The the amount of water a square mile would increase by, if only a few inches were the best case scenario could be the difference between a sea wall containing a Spring tide and flooding a coastal town! Worst case, a few metres could mean the evaquation of a city. Look at the New Orleans floods..........could this be a warning?

Did you know "a 2005 study by a scientist named Ola Johannessen and his colleagues showing that the interior of Greenland is gaining ice and mass and that according to scientists, the Arctic was warmer in the 1930’s than today."
"The National Academy of Sciences report reaffirmed the existence of the Medieval Warm Period from about 900 AD to 1300 AD and the Little Ice Age from about 1500 to 1850. Both of these periods occurred long before the invention of the SUV or human industrial activity could have possibly impacted the Earth’s climate. In fact, scientists believe the Earth was warmer than today during the Medieval Warm Period, when the Vikings grew crops in Greenland"
Ignore the scare mongers. They resemble chicken little more than than do scientists. Unfortunately there are lots of chicken littles around today

if ALL the polar ice caps melt everywhere (including Greenland)...we would be looking at a 300 foot rise...say goodbye to Florida, Louisiana, many of the eastern states, and much of California. That is just what we would lose in the USA, let alone the worldwide effect.

It's the expansion of the existing water that matters more than melting ice adding to total volume of water(water density decreases as temp. rises from 4C).Shift anyway as expansion plus melted ice from Greenland will make coastal areas places to escape from.

About 6 meters.
Surface area of Greenland = 2 million km2
Average ice thickness on Greenland = 1 km. (range 0-3km)
Volume of ice on Greenland = 2 million km3
Surface area of world's oceans = 360 million km2
Hence 0.006 km3 of additional water for each km2 of ocean, or an additional layer of 6 meters (0.006 km)

Perhaps someone should look into desalination plants that run on solar energy to re fill all the natural wells that have run dry leaving us lower seas and an abundance of fresh water to pipe to arid regions so to restore some kind of balance!!

Al Gore (remember him?) thinks it's going to rise dramatically; however, those who are experts in the field say this is not true. So it's only going to rise a few inches in the next several years.

Most projections are for a small rise of only a few inches.

do you have a globe? look at it.. look at the size of greenland.. look at the size of the ocean...
Even so, it doesn't all happen overnight... Coastal residents would just notice the beach is getting smaller... oops.. time to move!
