The way the modelling community tends to work is.... Obviously, there are different models out there. Let's talk specifically about climate change.
What the modelling community is trying to do is work together to ensure that, despite the fact we are using different models—I mean, there aren't 15 of them out there, but there are some—we understand what the underlying elements are of each of those models so that, when different people use different models, we can at least agree on what goes into the models.
