I got interested in uncertainty kind of right from the start of when I went into climate modelling, actually through joining a project which had a statistician involved - which was perhaps relatively unusual at that time – through a mutual friend of ours called Jonty Rougier, and I just got I got kind of bitten by the bug really. Of uncertainty, of exploring possibilities of being kind of open to not just thinking about the things that we didn't know, but trying to anticipate the things that might happen that we haven't yet, you know, the unknown unknowns and all of that, and the almost kind of philosophical aspect of trying to predict the future when we have all that uncertainty in how something behaves in something as complicated as the planet with a relatively limited amount of data to base it on and there's always going to be kind of limits to our knowledge. So I yeah, I just really kind of fell in love with the subject.
