Global warming could cause tsunamis in Britain as melting ice sheets throw the earth’s crust into disarray, scientists have warned.

Top: a map showing the location of channels buried under the North Sea 21.000 years ago, with a superimposition indicating the boundaries of the ice sheet. No other location is shown.

The crust still has much to do to get back on its feet as all of Greenland’s central parts are below sea level and pushed to the bottom by the mass of the three-kilometre (kilometer-mile) thick ice sheet, added Donald Slater, a glaciologist at the University of Edinburgh.

Future research should include shallow drilling, to better time zone tunnels, and a wider sweep of seismic data, the team said.

McGuire said faults in the earth’s crust had accumulation far too much molten ice over a very long period of time.

The therefore obtained data are the most detailed to date on the tunnel valleys undergoing construction under the North Sea.

The wave devastated Doggerland, a low-lying swampy island off the northeast coast of England that spans an area the size of Wales.

The high level of detail of these channels provides an insight into how the ice sheets, when forming, interacted with the channels.
