re: U.N. Predicts Disaster if Global Warming Not Checked

ooops, no rate increase of rising water levels

Technically you are correct but because you are being sarcastic with the "ooops" I bet you don't even realize why and this is part of the problem with the science discussion in the general public.

"Rate of increase" is analogous to acceleration and rate is analogous to velocity. That means the increase in global sea level rise would be nonlinear if there was an increasing rate. But your graph shows a linear rise. That means the rate of sea level rise has been consistent at 2.85 mm per year in New York harbor buoy since the 1850's. There has been no change in rate over that time period.

Here is another one for you:

That buoy location is in Key West Florida with a linear rise in sea levels of 2.42 mm/year. No increase in the rate of seal levels.

Here is another buoy location:

Here we have decreasing sea levels on a linear downward trend at a rate of 3.74 mm/year.

Here's another location with massive rate of sea level decrease:



That's a huge decrease in sea levels of 13.26 mm/year in Juneau Alaska. LINK

And here is another buoy location on the opposite end with increasing sea levels:

So what is going on? At some buoy locations the sea level is decreasing at some locations we see the sea levels increasing. Isn't water supposed to reach equilibrium? If so something else must be causing different rates at different locations.

I included the Grand Isle buoy for a reason. I'm very familiar with south Louisiana. South Louisiana has a land subsidence problem. Since buoy measurements are measured against a land or sea bottom benchmark what the Grand Isle buoy is actually measuring is the subsidence rate. The same goes for your New York buoy and the Key West buoy.

The opposite is true in the Sweden and Alaska charts I provided. We are seeing land growth at these locations.
