>"The total TTT trend found in this study was only one-half of the climate model simulations," the STAR researchers note. "Possible reasons for the observation-model differences in trends may include climate model biases in responding to external forcings, deficiencies in the post- millennium external forcings used in model simulations, phase mismatch in natural internal climate variability, and possible residual errors in satellite dat sets." Translation: The models simply run too hot, the historical inputs like volcanic aerosols and ozone to the models may be wrong, a temporary natural cooling trend could be masking warming, and adjustments t the satellite data may be wrong.
