Looks like Kristian is using Slayer approaches to argue with you Stephen (see July 0, 0000 at 00:00 PM). He says there is no IR-absorbed energy from below to fuel the evaporation b/c the IR source is from a lower temp. I'd have to go through all the comments on this thread to see who's specifically pushing the Slayer approach vs who isn't, but I wouldn't be surprised if almost all of the people I've argued with are using the Slayer misunderstanding as their reasoning.
