ABSTRACT
Global climate change influenced by "greenhouse effect" are felt and on the Romanian Black Sea seaside. Given that both in the air and sea water temperature were recorded a slight increase, it is likely that this was due to the thermal expansion and precipitation. According to the latest IPCC report, in 2014, the water temperature in the layer of 0 - 75m shows, so far, a global average warming trend of 0.11 [0.09 to 0.13] °C/decade [1]. This decreases the overall tendency from the surface to the intermediate layer, with a decrease from 0.04 °C per decade down to 200 m, and less than 0.02 °C per decade at 500 m depth.
The sea level is a dynamic parameter that influences the local coastal dynamics. Changes in the hydrological cycle are difficult to assess at this stage, but some features are obvious. The general trend of the sea level is of rising at a rate estimated at approx. 1.7 mm/year. Maintaining this rate, the average levels should increase to about 0.8m in 50 years or 1.7m in the next hundred years. This increased eustatic fluctuation have not as the source the Danube waters, whose flow is decreasing, if takes into consideration the available time series (1959-2004).
The 2014, in terms of trends to the reference period 1959-2013, presents a slight increase in sea surface water temperature (about 0.02 ° C / year) and the trend of salinity in the surface layer is possible to decrease by about 0,01PSU/year. The sea level followed the trend of the last decade, when annual averages were higher (32.4cm in 2005 and 38,7cm in 2010).
