Melting of land ice, unlike sea ice, increases sea levels very slightly. In the 1990s, Greenland didn't add to world sea level rise; now that island is adding about half a millimeter of sea level rise a year, NASA ice scientist Jay Zwally said in a telephone interview from the conference.
At 1/2 a millimeter a year, how long do you think it will take the coastal regions to become uninhabitable, fueling a recovery of the Chicago housing market?
