The rise in sea level of the Mediterranean is accelerating

"The sea level in the Mediterranean has risen by between 1 and 1.5 millimetres each year since 1943, but this does not seem set to continue, because it now seems that the speed at which it rises is accelerating", Manuel Vargas Yáñez, main author of the book Cambio Climático en el Mediterráneo Español, and researcher in the Spanish Oceanography Institute (IEO), tells SINC.

The publication, which in its second edition includes, for the first time, climate figures from 1943 to 2008 using a marine observation system which is unique in Spain and pioneering in Europe, confirms that the Mediterranean is becoming warmer. Its salinity is also increasing, and the rise in sea level is accelerating. Since the start of the 21st century the level has already risen by 20 centimetres.

However, "during the last three years which were added to the study (from 2005 to 2008) the rise in temperatures has been slower than at the end of the 20th century, when the sea temperatures rose significantly", points out Vargas Yáñez, who insists on the necessity to study long series of figures to show the impact of in the Mediterranean.
