I don’t myself visit Watts’ blog unless someone points to something particularly funny or egregious, and the comment threads are so long and monotonous it is even rarer that I go there.
That said, I am always grateful to others who have occasion to do that hard work and who come back out to highlight particularly mind-blowing examples of…of… of whatever it is that adequately describes what passes for dialogue over there. So, many thanks to Holly Stick over at Rabett Run who points us to the Gray Monk at WUWT who writes:
Actually the question is whether or not CO2 is the ‘evil game changer’ it is claimed. Research on nuclear submarines suggest a different scenario. The average CO2 level on an operational submarine may be as high as 2,000 ppm, but is generally around 700 ppm (I think Anthony has a post on this somewhere) which rather refutes some of the claims of ‘heat’ trapping as the submarines are able to maintain a fairly stable internal temperature, admittedly with air conditioning to regulate it. The bigger problem at the upper end of the scale is the narcotic effect on the brain. But at 700 ppm it is not measurable.
If Hansen et al are to be believed, these submarines should be unbearably hot after a very short patrol. They’re not. In fact some compartments have a heating problem.
