Why coastal flood maps are wrong: the tale of compound hazards

Coastal flooding is expected to increase in frequency due to future sea level rise and more extreme weather, but most coastal flood hazards maps do not portray the increase risk. We dive deeper into how these maps are made and uncover why the current flood hazard maps may be misleading.

Endangered Species Act: Headed for Extinction?

The Endangered Species Act (ESA) is a law designed to protect and recover endangered species of plants, animals, and ecosystems, and in turn, preserve our nation’s ecological history and functionality. However, there has been a recent push to overhaul the ESA in favor of economic opportunities. This would relieve the burden carried by landowners and industries who have been hampered by ESA restrictions, but would strip protections on species already listed on the ESA and make it more difficult to add species to the list. Left unprotected, those endangered species would be left to go extinct, and the ecological functions they serve within their ecosystem could collapse or irreversibly shift their biomes. With human activity responsible for current accelerated extinction rates, this is the time for urgent action on conservation, not a time to overhaul the law designed to protect our nation’s species and ecosystems.

The hidden value of coral reefs

Coral reefs act as natural breakwaters reducing wave energy along coasts and, thus, can mitigate flooding. Reef structures currently avert more than $4 billion of flood damage annually. The viability of coral reefs is threatened by rising ocean temperatures, changing seawater chemistry, and physical anthropogenic disturbances. The expected damages to coastal infrastructure from flooding would at least double if reef height is reduced by only one meter. The reduction in flood protection services underscores the importance of investments in reef management, protection, and restoration.

Reducing Plastic Pollution through Economic Incentives

Strolling along the beach, especially during peak tourist season anywhere and you will inevitably stumble upon someone’s cast away plastic bottle. Whether left by a beach-goer or washed onto the sand from upland, plastic litter can cost you the enjoyment of your beach day. Not only that, but collectively this nuisance plastic waste costs lost revenue from decreased tourism as well as harm to public, wildlife, and overall ecosystem health.
