As reported in the Intergovernmental Panel on ClimateChange’s (IPCC) Special Report on the Ocean and Cryosphere in a ChangingClimate , “[t]he ocean is essential for all aspects of human well-being and livelihood” and ocean warming, acidification and sealevelrise are impacting fisheries and food production and depleting key ecosystem services.
As it flowed south on its way to the sea, the river continually poured sediment into the basin, gifting it with fresh, nutrient-rich river mud that replenished the land and prevented coastal erosion. But some scientists warn that sea-levelrise is ultimately a wild card. Slowing down the bleed.”
The tide is turning against Louisiana’s proposed $2 billion Mississippi River sediment diversion project, that supporters say is needed to save the coast from rapid land loss due to subsidence, damage done by the oil and gas industry, extreme weather events, and sealevelrise quickened by climatechange.
The project’s supporters, including major environmental nonprofits like the Environmental Defense Fund, the National Wildlife Federation, and the Audubon Society, say large river diversions are the most effective way to send land-building sediment streaming into the bayou from the Mississippi River to fight land subsidence and sea-levelrise.
At best the permits minimize coastal erosion and gloss over storm surge and flood risks in relation to climatechange,” he said. Persistent gaslighting by many of Louisiana’s politicians wasn’t restricted to the climate crisis during 2022. Real science isn’t being used to guide their decisions.” Credit: Julie Dermansky.
Most often, climatechange is associated with a decrease in groundwater, fueled by worsening drought and evaporative demand. But in some areas, this water is actually creeping higher, thanks to risingsealevels and more intense rainfall , bringing a surge of problems for which few communities are prepared.

This makes it ripe for disaster capitalism, a phrase Naomi Klein coined in her book “The Shock Doctrine: The Rise of Disaster Capitalism.”

But four hurricanes since 2005 and sealevelrise — it really decimated this coastline.” He estimates that 70 metres of his property has been swallowed up by sealevelrise since he moved there in 1998, with trees and wetlands washed away as the ocean advanced bit by bit with each passing year.
