On this edition of Your Call’s One Planet Series, environmentalist journalist Tina Gerhardt discusses her new book, Sea Change: An Atlas of Islands in a Rising Ocean, which weaves together essays, maps, art, and poetry to show us—and make us see—island nations in a warming world and the impacts of sea level rise on islands around the world. Island nations have contributed the least to CO2 emissions and global warming, but they are suffering the brunt of it. Pacific Island nations are responsible for 0.03 percent of global emissions, according to the Intergovernmental Panel on Climate Change. Figures for islands in the Caribbean Sea are in a similar range. Tina Gerhardt highlights Indigenous and Black voices and communities working to save their nations, histories, cultures, and languages.
