"Climate displacement is becoming one of the world’s most powerful — and destabilizing — geopolitical forces."
"Climate change is not equally felt across the globe, and neither are its longer term consequences. This map overlays human turmoil — represented here by United Nations data on nearly 64 million “persons of concern,” whose numbers have tripled since 2005 — with climate turmoil, represented by data from NASA’s Common Sense Climate Index. The correlation is striking. Climate change is a threat multiplier: It contributes to economic and political instability and also worsens the effects. It propels sudden-onset disasters like floods and storms and slow-onset disasters like drought and desertification; those disasters contribute to failed crops, famine and overcrowded urban centers; those crises inflame political unrest and worsen the impacts of war, which leads to even more displacement."
