A guaranteed future for low lying areas in in US jurisdictions is in jeopardy according to the US Department of Defense. This means massive infrastructure costs to protect what can be saved, but also investing in harm reduction strategies as well.

The impacts of climate change are accelerating around the world, but perhaps nowhere faster than for islands and coastal areas. In fact, a study by the United States Department of Defense suggests that more than a thousand low-lying tropical islands risk becoming “uninhabitable” by the middle of the century as rising seas bring battering waves, aquifers inundated with salt water and, eventually, full submergence. For these communities to survive, we must find ways to reduce the emissions driving climate change and help them adapt to the impacts they already experience. For coastal communities, an overlooked set of solutions—protecting coastal wetlands and the blue carbon they store—could help with both goals. What is Blue Carbon? Despite international progress made since the 2015 Paris Climate Agreement and accelerating renewable energy investments in the years since, technological solutions alone probably won’t keep our climate in safe boundaries. We must also invest in natural climate solutions—practices that maximize the carbon storage potential of our natural ecosystems. When considering natural climate solutions , forest carbon—avoided deforestation and reduced-impact logging, for example—attracts most of the limited attention. But coastal wetlands—tidal marshes, seagrass meadows and mangrove forests—sequester billions of tons of carbon from our atmosphere at […]
