During the most recent ice age (about 20,000 years ago) the world's sea level was about 130m lower than today.
Since early 1970s, global sea level has risen an average of 3.2 mm a year. Glacier mass loss and ocean thermal expansion from warming together explain about 75% of the observed global mean sea level rise.
End of 21st century, very likely sea level will rise in more than about 95% of the ocean area, 70% of coastlines worldwide expected to experience sea level change. Hurricane Sandy- city becoming aware that action needs to be taken (Lower Manhattan Resilliency Project)
