As pollution levels rise, the planet warms and sea-levels rise, planning for environmental challenges is crucial. William Moomaw, Gillian Davies and Max Finlayson explain why wetlands, storing huge quantities of carbon, are some of the world’s most undervalued weapons against climate change. When disasters do strike, Daniel Aldrich explains how social media influences decisions on whether people evacuate or stay in place. Meanwhile, Luciana Esteves argues that sometimes relocation is the only safe climate-proof response.

But it’s not just natural disasters that need to be planned for. Britta Denise Hardesty, Chris Wilcox, Kathy Ann Townsend and Qamar Schuyler argue that if we can estimate how much plastic it takes to kill a turtle, we can figure out just how much of a threat plastic is to endangered sea turtle populations.
