where we overview the challenges of skillful multi-decadal regional and global climate predictions. Not only must current multi-decadal climate statistics be accurately calculated, but CHANGES in these statistics must be skillful.

the global models have not yet passed the needed tests.
“Better models are not what is needed, in my view, but a new approach to assess risk from climate and other environmental (and social) threats as we present in our second paper listed above.
