This suggests to me that he was getting the basics more or less right, which in turn emphasises the point that the best
models and theory we have all
predict and have consistently
predicted the same thing: warming, and quite a bit of it
by the end of this century if we keep dumping CO2 in the atmosphere at our
current rates.
Kevin Hamilton, who co-authored the report, warns: «If our

by greenhouse gases than
current global
models predict, and even the highest warming predictions would underestimate the real change we could see.»

My Reply - Even IF the climate
model could
predict the
current statistics of the occurrence of ENSO, the NAO, the PDO, etc [which is proving quite a daunting challenge], this,
by itself is not sufficient to justify their use to provide projection of CHANGES in the statistics of ENSO, the NAO, the PDO, etc events in the coming decades.
A significant and serious concern among mainstream climate scientists in this regard is the inability of the
models to
predict climate surprises, that is, rapid non-linear changes in the climate system that have happened in the historical climate record and that may be triggered
by current human activities.
Since the only climate crisis is a
predicted one, and the
current models have no predictive skill (either theoretically,
