Precis:

The sea level is getting higher. Forecasts indicate in 2007 that sea level grow about 28cm by the year 2010. It is a global average. The researchers began to study different regions of the world. The biggest impact on sea level rise are:
- ocan currents
- differences in the temperature
- salinity 
- land movements.                                                                                                             
The global warming is imprtant in this topick, because it has influence on the currents. The biggest rise in sea level is expected to be in New York. An interesting occurrence is that in the areas closer the melting ice, sea level will be smaller than futher away. 
If the ice melts, the sea level will rise, but gravitation force decreases, so the local water levelmay decrease. There are many uncertainties in this studies, but it is certain that some parts of the world sea level to rise faster than other parts.
