"Data from a US space agency (Nasa) satellite show that the melting rate has accelerated since 2004." -- DA Morgan

Just a question... why did you pick 2004? Greenland has been affected greatly by a volcano that erupted in 1992. If you compare today's rate with 1991, we are still in better shape. How sure are you about your data and your conclusions? Without examining that first, all the hoopla about rising sea levels and which cities will get wiped out is pointless.
