"Sea level reaches record high: Following sharp decreases in global sea level in the first half of 2011 that were linked to the effects of La Niña, sea levels rebounded to reach record highs in 2012. Globally, sea level has been increasing at an average rate of 3.2 ± 0.4 mm per year over the past two decades."

I listened to an interview with Dane Wiggington a scientist who has uncovered what chemtrails is doing to the earth and he predicts a 21 foot rise when Greenland completely melts. I have heard before that a 3 foot rise would take out New York City and they have just decided to build more and higher sea walls, this seems to be more serious than I thought. Trusting NOAA with the correct figures is questionable.
The raises mentioned are small, but as it grows, it is predicted to take out coastal cities. But the methane is a problem, no doubt.
I don't consider that the real problem, the real problem seems to be the methane releases because the ice is melting.
