Well, I just went to the CCNF website and read one of the first articles I saw:
http://climatechangenationalforum.org/dr-james-white-atmos-co2-changes-from-180-to-280-ppm-between-glacials-interglacials-we-just-hit-380-ppm-2009-last-time-we-had-380-was-3-million-years-ago-arctic-was-ice-free-sea-level-was-7/
Dr. White seems to think that we might get 75 feet of sea level rise because CO2 levels are now over 380 ppm, and he states “Bye bye to Florida for the most part.”
If this is the level of science on that blog, then count me out. This particular blog post is unfortunately, quite ignorant of solid, recent science.
To try to be fair to CCNF, there is some gentle dissent to White’s prognostications. Dr. Schmittner says “The 380-400 ppm is a good estimate, although 75 ft seems a little high…” And Dr. Pelto says “Will just point out some recent research indicating soils that have been buried continuously beneath the Greenland Ice Sheet for the last 3 million years….”
But these comments are far too mild. Any scientist knowledgeable about sea level rise in the last several million years would be aware of the recent science on Greenland. To wit, during the Eemian, the previous interglacial, Greenland was 8 degrees warmer than today for 6,000 years, 60 centuries. And during that considerably warmer time period it lost about 1/4 (one quarter) of its ice. That is less than two meters of sea level rise over 60 centuries, or a bit over an inch a century. Here is the link:

And the key quote: “But despite the warm temperatures, the ice sheet did not disappear and the research team estimates that the volume of the ice sheet was not reduced by more than 25 percent during the warmest 6,000 years of the Eemian.”
Surely that says that Greenland will contribute very little to sea level rise in a warmer world, even a warmer world that stays warm for two or three centuries.
What Dr. White seems to think is that both CO2 and temperatures will continue to rise for, seemingly, many centuries to millennia. But surely the world will switch to solar as soon as it becomes cost effective, which is likely to start somewhere between 10 and 20 years from now for urban locations (sides and tops of buildings) in places like the US.
Solar is already the electricity technology of choice in rural Africa and India; it is even possible that as with cell phones (which leapfrogged land line technology, making it obsolete before it was built in places like Thailand), solar panels might make an electric grid obsolete, at least for a while, in many rural and developing parts of the world. All the while becoming cheaper with more manufacturing.
The point that Dr. White studiously ignores is that society isn’t going to keep on burning fossil fuels at an ever increasing rate. His scenario cannot come about unless we continue, as a world, to keep increasing CO2 for several centuries to come, and no one wants or will allow that to happen.
So it is hard for me not to see this new web site as tending toward alarmism.
