Although model-based projections of future climate are now more credible than ever before, the authors note they have no way to say exactly how reliable those projections are.
Cognitive dissonance masquerading as science.
Their "test" of the new models is worse than useless.
These same morons have been arguing that the data of the last 60 years is flawless. Yet they fail to "predict", using their "improved" models, the climate for the 60s, using the data of the 50s because they would fall flat on their interchangeable body ends...
Credible but not reliable.
Sounds a bit like “fake but accurate”.
