Sea level rise is accelerating the loss of ecological and economically critical coastal wetlands. In a new peer-reviewed study, Climate Central modeled the outcomes for American coastal wetlands based on three factors: how fast seas rise, how much undeveloped land is conserved for wetlands migration, and how fast wetlands can grow vertically. We found that conserving land for wetlands migration is a decisive factor in whether coastal wetlands thrive or drown. Assuming moderate wetlands growth and modest cuts to emissions, conserving all available land for wetlands migration would limit coastal wetlands loss to a 17% reduction in wetlands area by 2100, down from a 63% reduction if all that land is developed. To complement our research, we have built a pair of interactive mapping tools which allow users to explore the possible futures of coastal wetlands in their area. This presentation will share our findings and demo our interactive maps.
