Point/Counterpoint

In "Open Source Climate Model Development Is Worth It," Isaac Held explains that a fully open source climate-modeling effort could be of great pedagogical value and maybe even of direct scientific importance by providing a toolbox for active researchers and people new to the field. In "Should Climate Models Be Open Source?" David Randall explains that ommunity-based climate model development can be facilitated by coding the model in a modular fashion, but it can cause problems because the real climate system isn\´t modular.
