On the ancient glaciers and global sea level

An international team of scientists from France, Japan and the UK has shown that during one of warming and melting glaciers about 14,600 years ago in the world's oceans has lived critical flood. Period is known Bolling warming. Then the water level rose by as much as 14 meters as a result of the collapse and the melting of huge blocks of ice.

The study was carried out in 2005 as part of the expedition. Tahiti. The fall of the glacier into the ocean has been called Melt-Water Pulse 1A (MWP-1A). The main source of information have become fossilized coral samples from the interior of the coral reefs of the island, as these creatures are extremely sensitive to any changes in the environment. In addition, this is a fairly accurate gauge of time, because the error in the calculations using the coral is only 30 years old.

The choice fell on about. Tahiti, as it is located at a great distance from the place where underlain glaciers, and thus may help in determining the mean sea level for the entire planet and make it more accurate.

Most of the water in the ocean come from Antarctic glacier. While scientists are not restored the chain of events that led to the collapse of the ice blocks during the last warming. It is not known what was the first, global warming, caused massive melting of glaciers and the influx of fresh water, or is it melted water has spurred further growth temperature.

Scientists sincerely hope to successfully complete their research, which will help to model scenarios of climate change, the key to control the behavior of modern glaciers and ultimately make more accurate predictions about the level of water in the ocean and warming.

To date, half of humanity (about 3.2 billion) live within 200 km of coastline. One-tenth of the world's population is below 10 meters above sea level. For all these people, as for the Tahitians, it is important that the issue of global sea level did not remain unresolved.
