a rising sea level is not the only risk Britain faces from climate change, according to a paper that warns that warmer oceans also mean more storm damage, disease and job losses.  Previous studies on the effect of rising temperatures on the oceans around Europe have concentrated on coastal erosion and rising sea levels.  The new study suggests the rise in temperature will cause storm surges and flooding across coastal Europe. In Britain that will mean 20 per cent more damage from extreme weather events every year. In warmer seas bacteria is able to thrive. In the UK, this will mean a rise in poisoning from infected shellfish.  Ocean acidification and less oxygen in the sea will harm many species. as certain fish move north, some jobs will be lost.  a collaboration of European institutions, known as Project CLaMER, looked at reports on climate change and the marine environment published since 1998. Carlo Heip, director of the Royal Netherlands Institute for Sea Research, said: "We must all heed the clear warnings of the hazards we face from what amounts to an uncontrolled experiment on the marine environment."
