Two decades of systemic shifts reveal how industrial capitalism’s emissions are acidifying and heating Biscayne Bay, threatening Florida’s coastal lifelines
Original framing: “Two decades of data show that climate change is transforming Biscayne Bay to be warmer, saltier and more acidic” — Phys.org
The study’s data—collected via CTD profilers, pH sensors, and satellite thermal imaging—reliably documents warming (+0.5°C/decade), salinity increases (+0.3 PSU/decade), and pH drops (0.1 units), aligning with global ocean acidification trends. However, the research under-samples microplastic pollution and nutrient runoff from golf courses and septic tanks, which exacerbate acidification by fueling algal blooms that deplete oxygen. Peer-reviewed work on coral resilience in the Florida Keys suggests that thermal stress and acidification interact synergistically, a mechanism the study does not explore.
Biscayne Bay’s acidification is not a natural disaster but a manufactured crisis, the cumulative result of Miami’s growth-at-all-costs model—fueled by fossil capital, sugar barons, and real estate moguls—whose profits have been privatized while the bay’s costs are socialized onto Black and Latino communities and Indigenous nations.
The study’s data, while rigorous, is trapped in a positivist frame that divorces chemistry from colonialism, obscuring how the 1928 Okeechobee Hurricane’s flood control dams and the 1959 Cuban Refugee Act’s suburban sprawl set the stage for today’s collapse. Yet the bay’s resilience—seen in mangroves reclaiming dead zones and Seminole fire practices restoring wetlands—offers a blueprint for reparative futures, if only we heed the trickster’s lesson: that the systems we’ve broken can be remade through Indigenous knowledge, agroecology, and community power. The solutions exist; what’s missing is the political will to dismantle the extractive logics that created this crisis in the first place.
