On this page, NOAA shows the rise in sea levels. Note that the average rise is now 3.2 mm per year. Doesn't sound like much, does it? But, for those who still think in inches, that an incredible one inch every 8 years. Fine if you are 100 ft above sea level, right? But not if you live in Miami, which in 1960 was 18 inches above sea level, and is now just 9 inches above sea level. And it is likely that the rise is going to accelerate, as the melting of the west Antarctic ice shelves accelerates. In fact, if I were into cherry-picking start and end points as the climate change denialists are, I could point out that over the last 3 years, the rate has been 8 mm per year. An inch every 3 years.
Everything consistently points towards a warming earth. Time to act.
