But when those same models failed to anticipate the lack of warming over the past decade or so, the IPCC admitted that their models failed to account for the fluctuations in natural forces.
In other words, if it warms, we have the models right and man is the cause. If it doesn't warm, we don't have the models right.
Just not reliable enough to me.
