I searched on "temperature rise over last 120 years" to find the data I used, what did you use to find data that showed much less than a 0.07 degree increase?
Discussing sea level rise will take more time than I am willing to spend. Some data points I found:
- The 432ft rise was from 21,000 years ago to about 3,000 years ago
- At the end of the 432 ft rise the seas were at their current level which means there was a great deal more ice to melt in those 18,000 years than there is now
- While 8" over 120 years seems correct it is important to know that half of that was over the last 30 years indicating the rate of sea level rise is increasing
- The seas will not rise another 432 ft (not enough ice) but at a rate of more than one foot per century and increasing, sea level rise could be a big problem not too long from now

Well, whether it be a 10,000 or 18,000 year period to rise 432 feet, I'm sure in those 100-180 centuries there were periods where the rise was more in a 30 year period than the other 70, which of course means that an increase in the rate of rise was followed by a decrease. Again, we are talking hundreds of thousands of year cycles over the last 4 1/2 million years of the current ice age. The last 30 years is not reflective of anything---we simply don't have enough data over a long enough period to know.
