They admit that we had virtually no ocean data that has 1000 times the heat capacity
of the atmosphere and is in direct contact with the atmosphere yet they are willing to make predictions without really any
robust data from that variable data at all (pre-2000) and they admitted they didn't understand
clouds yet that variable could easily swamp all other
effects yet they said with 95 % surety the heating from 1975 - 1998 was caused by CO2 (110 % according to Gavin).
