You would now use laser measurements from satellites, which are very accurate. Sea level measurements in the past were very difficult to judge accurately.
Yes, the enhanced greenhouse effect is the reason of melting the ice of north pole.
If the North Pole keeps melting, it will have an end.
In the Arctic the polar ice cap is melting, losing about 3% ice every year. In the summer of 2007, for the first time in recorded history, the North-West Passage was open for shipping.
This higher temperature may be causing some floating icebergs to melt, but this will not make the oceans rise. Icebergs are large floating chunks of ice. In order to float, the iceberg displaces a volume of water that has a weight equal to that of the iceberg. But the rising temperature and icebergs could play a small role in the rising ocean level. Icebergs are chunks of frozen glaciers that break off from landmasses and fall into the ocean. The rising temperature may be causing more icebergs to form by weakening the glaciers, causing more cracks and making ice mo re likely to break off. As soon as the ice falls into the ocean, the ocean rises a little.
•The rising air then proceeds south and north toward the poles. From approximately 20° to 30° North and South latitude, the air sinks.aTT: Sheila
Rising of the North happened in 1569-11.
The level remains the same, revealing that melting (north) polar ice wont alter the sea level
North moon is the main cause because
Yes, the enhanced greenhouse effect is the reason of melting the ice of north pole.

spinosaurus thought that the carcharodontosaurus was tyrannosaurus rex that's why they get into fights.
due to the melting of the icebergs the water levels are rising real quickly Rubbish icebergs are floating they displace exactly their own volume of sea water. Don't believe everything you read, try doing a little research yourself you might just be surprised at what you find. It is even possible you might discover the truth.

The water at the south pole is not melting till now. But the melting water from the north pole will elevate the ocean water and then we are flooded near the coasts.
he went to the north pole
because the ice at north and south pole has melt
The north pole and the south pole melting causing sea level to rise dangerously. http://abcnews.go.com/Technology/GlobalWarming/story?id=1678441&page=1
