The level of the Mediterranean Sea is rising rapidly and could increase by up to half a metre in the next 50 years, scientists in Spain have warned. 
A study by the Spanish Oceanographic Institute says levels have been rising since the 1970s with the rate of increase growing in recent years.
It says even a small rise could have serious consequences in coastal areas.
The study noted that the findings were consistent with other investigations into the effects of climate change.
