Increasing Concern over Rising Sea Levels; Environment Today

Article excerpt

IN the last thousand years, sea levels have risen by an average of less than half a millimetre a year.

But in the last 100 years, that rate has tripled. And in the last 15 years, it has doubled again, said Dr Glenn Milne, Reader in Geophysics at Durham University, who studies climate change-linked sea level rise.

Much of the sea level rise around places like the North East is as a result of melting mountain glaciers, said Dr Milne.

"These glaciers are getting smaller and if it keeps going there won't be many left in the next 100 years or so," he warned.

But the big worry is what happens to the Greenland and Antarctic ice sheets.

The total Antarctic ice mass represents 55-60 metres of sea level, said Dr Milne.

Another factor of climate change is that as the oceans warm, the water expands and sea levels rise.

Over the next 100 years this could result in rises of tens of centimetres.

But Dr Milne said that it was a misconception that sea levels will rise globally in a uniform way. …
