The 2007 IPCC report was full of mistakes, like the claim that Himalayan Glaciers would be gone by 2035. Another error appears to have been a graph which indicated 2mm/ sea level rise per year
a “best estimate” by the UN’s Intergovernmental Panel on Climate Change (IPCC) in 2007, which projected that by today, the rise would be 2 mm (0.078 inches) per year.
AFP: Seas rising 60% faster than UN forecast: study
If the IPCC did say that, it was an error. The sea level graphs which their numbers are based on showed more than 3.1 mm/year prior to 2007, and a sharp slow down since 2007.

Based on this nonsense, the Washington Post reports :
a group of climate researchers released calculations that indicate the world’s oceans are rising 60 percent faster than the U.N. Intergovernmental Panel on Climate Change anticipated five years ago
sea levels appear to be on track to rise by several feet over the next century, with every inch putting more Americans at risk. Sea-level researchers Robert Kopp and Benjamin Strauss estimate that a five-foot rise would produce Sandy-like floods in New York every 15 years, on average.
Holding back the sea – The Washington Post
An honest statement would be that the train has fallen off the one foot per century track, and that since 2007 sea level is rising 50% slower. The Washington Post is engaging in classic Soviet journalism.
We finished second, and the other team finished next to last
