Yes, that's a really good question.
As a lot of people are aware, the United Nations publishes, on a periodic basis, a forecast with respect to the global impacts of climate change. On that basis, within the PBO, we've actually taken that modelling and mapped it to ECCC's modelling of rainfall and temperature levels at a very granular basis across the country. On that basis, in turn, we've used it to feed into our macroeconomic model.
We published a paper in 2022 based upon this micro-information, again drawing from the UN and from the government's own data from ECCC on a very granular basis to update our macroeconomic modelling. That, in turn, feeds into our fiscal modelling and our other models because, of course, the predictions that we're making are based on other people's predictions. At the same time, it's important to have something on the table so that people can plan around it.
