Why they need to talk to each other:
Most of climate science is in ‘shut up and calculate’ mode. This is a very dangerous place to be given the substantial uncertainties, ignorance and areas of disagreement, not to mention the problems/failures of climate models. Climate science needs reflection on the fundamental assumptions, re-interpretations, and deeper thinking. How to reason about the complex climate system, and its uncertainties, is not at all straightforward. And then of course there are the ethical issues, including understanding how the climate debate has gone so badly wrong.
