Disclaimer. After nearly 40 years managing money for some of the largest life offices and investment managers in the world, I think I have something to offer. These days I'm retired, and I can't by law give you advice. While I do make mistakes, I try hard to do my analysis thoroughly, and to make sure my data are correct (old habits die hard!) Also, don't ask me why I called it "Volewica". It's too late, now.

BTW, clicking on most charts will produce the original-sized, i.e., bigger version.

Rising sea levels

If you look across the evidence that global warming is real, everything is consistent: air temperatures are rising; sea temperatures are rising; glaciers are retreating; Arctic ice extent is at record lows; the Greenland and Antarctic icecaps are melting; and sea levels are rising.

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.
