Abrahm Lustgarten's work, The Great Climate Migration, uses both individual human stories and data modeling tell the story of how climate change has already begun forcing people to flee their homes, and how it is likely to cause unprecedented levels of human migration... 'If you look at any issue through the lens of climate change, you can start to see its fingerprint,' he said. 'A larger takeaway is that this is the kind of issue that starts to show the real human impact of climate change, rather than looking at the science and debating facts and figures.'
