When coral reef records were analyzed, it was found that recent climate variability had lessened as compared to the period from 1850-1920. Additionally, climate variability appears to be associated with the Pacific Ocean's ENSO cycle, not CO2. Further empirical evidence that the IPCC climate models are incapable of any degree of correctness.
