According to the UN panel, sea level rise was supposed to be about 6 inches per decade, but it seems a linear trend was suggested. However, if you look at past ice ages sea level rise could have been about 100 m, ofcourse it might be less if only a part of the artic and antartic zones are thawed, but could this be nonlinear? In other words, could sea level rise due to global warming be linear for the first degree or two and then accelerate?
