Mr. Paul Price:

I did not mean to misconstrue it. That is absolutely essential. We saw it play out really well yesterday between the committee and the Climate Change Advisory Council regarding the carbon budget committee. There was a brilliant back and forth about that. It was a brilliant example of what can happen and what needs to happen more often. We also saw this with the Citizens' Assembly, which was leading edge.

The issue of model types came up a lot yesterday, and it has been raised here. We have models for economic optimisation, but really we need modelling. Professor McMullin and I have talked about this. One really needs to play out scenarios in order to ask what is the worst case, to look at the worst-case scenario and to plan to avoid that. One of the worst-case scenarios is not meeting the Paris Agreement quantity budgets. We must look to see how we can do that. That would create positivity and show that we are really thinking about this. It is important.

At yesterday's meeting, Dr. Hannah Daly referred to openness of models. This is extremely important. If we are going to talk between us, between policymakers and scientists, and between scientists looking at what other scientists are doing, then things must be open. We need open data and open modelling. Professor McMullin has been pushing for this for years. It is super important. I was a bit alarmed when there was talk yesterday of agricultural modelling being too difficult for us to look at. That is not good. We must have open modelling, which is essential to these discussions.
