If the latter can benefit from CCS technologies, albeit in a small way, let us proceed full steam ahead.

Scientists have clearly established that global warming is due to CO2 / GHG emission post the industrial revolution. I also know of quite a few Princeton Ph.D qualified scientists who have worked with the IPCC and hold views which are quite different from that attributed to a particular faculty there.

Cost is always a factor. Dr. William Happer at Princeton University presented an on campus collquia CO2: Friend or Foe? within the last year or so. That presentation is available as an archived presentation if anyone is interested. I also have the PowerPoint set of slides that accompanied that presentation. Dr. Happer presents data that show temperatures rising BEFORE CO2 concentration increases in the Vostok Ice core data. What led me to recall that data was the indication from the data in this white paper that shows increasing temperatures (the slope of the curve) at a time which proceeds widespread burning of hydrocarbon by humans. Dr. Happer also presents data showing CO2 concentration in the geological past at levels as high as 7,000 ppm in the Cambrian, 2,500 ppm in the Jurrasic with an almost linear decline from that 2,500 ppm value to the 380 ppm value we measure today. That decline emphatically happened due to natural causes, not because of CCS technology. I would further find issue with the white paper in its reliance on the IPCC. The data and personal integrity of some of the participants in that group has been called into question. While this author embraces the truth of variability in average global temperatures over time, I do not embrace the concept that (1) it means the end of the earth for humans and (2) that humans are in any position to actually do anything about the variability. The universe is not static, nor is Earth's climate. The American Physical Society has just opened a new group dedicated to the real science of global climate variability. The group should provide a great deal of positive input to this discussion over the coming years. Recent publications seem to infer that CCS will not be viable for a variety of reasons.
