TEMPERATURES AND CO2 AND RECENT COOLING
The annual USHCN V2 shows the same cyclical pattern discussed above in the oceans and sun. The Industrial Age went into high gear after WWII. Yet temperatures for the period from the 1940s to the late 1970s fell even as CO2 increased. The Temperatures after the Great Pacific Climate shift of the PDO in the late 1970s began to rise and paralleled the CO2 rise for two decades to the super El Nino of 1998. After that, the Pacific flipped back to the cold mode and temperatures stopped rising and after 2002 began falling.

With a cooling Pacific (PDO and La Nina) and an extended solar minimum, one would expect cooling global temperatures. The MSU satellite data for the lower troposphere from the University of Alabama at Huntsville (Christy and Spencer 2008) shows that has been the case since 2002 despite a continuing rise in atmospheric CO2 by 3.5%.
