 Recently there have been calls for discipline-level changes in the practice of climate modeling, in order to better serve some of the purposes just mentioned. To improve climate change projections, for instance, Shukla et al. (2009) call for a “revolution” in climate modeling, such that both expertise and computing power are consolidated in a few international modeling centers, allowing for much-higher-resolution simulations. Katzav and Parker (2015) critically examine this and other leading proposals and reflect on their potential benefits and costs.
