They asked Muller the wrong questions. Warming is miniscule, and the little warming we have seen isn’t primarily due to CO2.
Muller’s graph shows very clearly the effect of the PDO on the “global temperature.” Around 1940 and 1977, PDO polarity reversed. Warming is associated with a positive PDO. The PDO is now negative and there has been no warming over the last decade.
