I'm quite clearly not a climate modeller, although I have in my life worked on a number of occasions with climate modellers. It's a very complex exercise. It's not magic. It's mathematics. We use modelling in all sectors of our society. We use it in the economy. We use it in health. We use it in employment sectors. We use it in the climate change sector as well.
We have provided information, and you have our chief modeller—I don't know if it's your title, Derek, but let's call you that for the sake of argument—here with us today, so he can answer your questions.
I'll be the first one to recognize that it is complex, and you want simple answers. I'm sorry. There's no simple answer when it comes to climate change or modelling.
