claim: A recent study led by Lawrence Livermore National Laboratory climate scientist Ben Santer found that while the models ran hot, the ‘overestimation’ was ‘partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.’
evidence: While it is believed that the modeled climate-cooling-effects from the mass of soot injected into the stratosphere by 100 firestorms ( one to five teragrams ) would have been detectable with technical instruments in WWII, five percent of that would not have been possible to observe at that time.
