I also want to follow up on a question from the previous panel that my colleague Mr. Johns asked about climate refugees. It was about 20 years ago that a Canadian author named Gwynne Dyer wrote a book called Climate Wars. At the time, it was very prophetic in terms of how people would be displaced because of climate and the huge issues it would cause for urban centres and for conflict.
I wonder if you could comment a little on the impact that climate is having on migration.
