claim: Sea level rise of 65 centimeters, or roughly 2 feet would cause significant problems for coastal cities around the world.
evidence: For example, in 2007 the Intergovernmental Panel on Climate Change ( IPCC ) projected a high end estimate of 60 cm ( 2 ft ) through 2099, but their 2014 report raised the high-end estimate to about 90 cm ( 3 ft ).
