Ulric:
You Fibber! 
Actually, I did follow the debate for a while. It all seemed to boil down to that the large variations in Model Output means that GCM's can never be wrong statistically within a range of +-2.5C in the next 50 Years. So, does this mean turning them all off and rolling a Die instead will tell us just as much and be alot cheaper (plus save on co2 emissions from all those PETAFLOP Supercomputers using all that energy) 
P.S. I notice Hadley isn't even in the Top 100 Supercomputers anymore. Infact I don't think the UK has any non-military Petaflop Supercomputers, except for the one at Edinburgh Uni I think.
