Here is the sea level rise in the last century. Note that the trend has not changed much since the early years of the twentieth century, when CO2 emissions were a small fraction of what they are today. If the trend continues, the sea level will be less than a foot higher in another century or two.

you may be right but there is serious and rapidly increasing ice melting in greenland which cannot be explained other than warming temps It is not true that only warming temps can explain melting glaciers in Greenland. Increased volcanic activity can also be responsible. Of course, one cause does not rule out the other. EARTH'S HEAT ADDS TO CLIMATE CHANGE TO MELT GREENLAND ICE researchnews.osu.edu Furthermore, just to reiterate a point which should be obvious but is not, observed warming temperatures do not in themselves prove anthropogenic global warming. The climate has been warming since the end of the Little Ice Age in the middle of the 18th century. If all the ice on greenland goes the seas rise 20 ft. Nobody but Al Gore even suggests such a thing.
