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.

“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.
