For 150 million people living in coastal areas around the world, rising sea level will become a genuine threat according to a new international study which found convincing evidence the sea level has been rising over the past 200 years - and continues to rise.

Lubrication to add a maximum of 8mm by 2200 Concerns that melting water would speed up the decline of Greenland's ice sheet have been allayed by new research which shows the lubricating effect of water beneath glaciers will not significantly add to sea-level rise.Scientists had feared that melt-water that trickles down through the ice could dramatically speed up the movement of glaciers as it acts as a lubricant between the ice and the ground it moves over.But in the paper'Enhanced basal lubrication and the contribution of the Greenland ice sheet to future sea-level rise', a team led by scientists from the University of Bristol, found it is likely to have a minor role in sea-level rise compared to other effects like iceberg production and surface melt.The results of computer modelling, based on fieldwork observations in Greenland, revealed that by the year 2200 lubrication would only add a maximum of 8mm for that year to sea-level rise - less than 5% of the total projected contribution from the Greenland ice sheetIn fact in some of their simulations the lubricating effect had a negative impact on sea-level rise - in other words it alone could lead to a lowering of sea-level (ignoring ...

Due to global warming A new study estimates that global sea levels will rise about 2.3 meters, or more than seven feet, over the next several thousand years for every degree (Celsius) the planet warms, Science Daily reports This international study is one of the first to combine analyses of four major contributors to potential sea level rise into a collective estimate, and compare it with evidence of past sea-level responses to global temperature changes.Results of the study, funded primarily by theNational Science Foundation and the German Federal Ministry of Education and Research, are being published this week in theProceedings of the National Academy of Sciences."The study did not seek to estimate how much the planet will warm, or how rapidly sea levels will rise," noted Peter Clark, an Oregon State University paleoclimatologist and author on the PNAS article. "Instead, we were trying to pin down the 'sea-level commitment' of global warming on a multi-millennial time scale. In other words, how much would sea levels rise over long periods of time for each degree the planet warms and holds that warmth?""The simulations of future scenarios we ran from physical models were fairly consistent with evidence of sea-level rise from the ...
