Koko Warner works at the UN university and is a world authority on an issue which is gaining more and more attention: climate change and displacement. Warner has undertaken pioneering work on environmentally induced migration and was a lead author for the recent IPCC report on adaptation. Despite headlines describing a “prophecy of doom” with hundreds of millions of people displaced, as the Climate Change and Migration Coalition argued, the report suggested migration could provide ways for some people to escape the worst impacts of climate change, and expanding opportunities for mobility may reduce vulnerability for many populations. This marked some change from the last IPCC report, but is reflects current thinking on climate migration.
