Reply to "Ice Breaker Gets Stuck Trying to Rescue Global Warming Scientists Trapped in Antarctic Ice"

Have sea levels risen, yes! Have they risen to the projected levels, no!    Melting ice on land, Greenland, will raise sea levels.  Melting ice on water will not raise sea levels.  Freezing expands the H20 volume, melting decreases the volume. 

 

Again, there were extreme warming periods -- during the high point of the West Roman Empire's expansion and during the medieval era. Which was punctuated by very cold eras -- the last called the Little Ice Age.  Human activity didn't cause those warming periods.  And, didn't cause the last one, which appears to be stabilizing and will decline.
