Ten to thirty inches of sea level rise this century. That is what the latest report of the Intergovernmental Panel on Climate Change (IPCC) says. We should be so lucky. Those summary 'headline' numbers are misleading to the poimt of being irresponsible.
I don't mean to be disrepectful of the IPCC's generally excellent review of climate science, but the way they portray sea level rise is deceptively low, just like their last report issued in 2007. This really is worth understanding and sharing so that we can realistically assess what is possible for sea level rise in the decades ahead.
Let me explain what the IPCC includes in those figures, what they don't, and why many scientists think they are creating a very wrong impression. Even most journalists and policy makers are left with the impression that three feet of sea level rise ("SLR") is the worst that could happen this century. That could very well be the best case on our present course. (BTW, even three feet of SLR would be a huge problem, considering that the shoreline moves about 300 feet inland for each foot of SLR, as a global average.)
The 10-32 inches (26-82 cm) cited in their table SPM2 is a just a summary of the chapter about sea level, but it is as far as most readers get. You can see the full report online, or I will reproduce the relevant part of that table here.
