Then when climategate
triggered me to closely examine everything, notably the IPCC's attribution argument, I realized that the fingerprints were «muddy», the climate models are running too hot, the forcing data is uncertain, no account is made for
multidecadal and longer internal
variability, and they have no explanation for the warming 1910 - 1940, the cooling 1940 - 1976, and the hiatus since 1998.
