"One reason is that the cost of control is likely to be much lower than the cost of rebuilding the World. Coastal cities could be abandoned and rebuilt inland, for instance, but improving energy efficiency and reducing greenhouse gas emissions in order to stave off rising sea levels should be far more cost effective."

Please note - the claim is that the control of greenhouse gases will REMOVE the need for dealing with the consequences. THAT is what I object to- the charts presented by Wolfgand, and the data on OTHER planets lead me to think we will still have to deal with those increased seal levels. - But without the industry to be able to support the effort.
