The report analyzes disinformation surrounding the Saguaro Project, finding that a significant portion of content on Facebook (43%) and YouTube (39%) used misleading narratives to frame the fossil gas project as a climate solution and driver of economic growth. Government accounts and media outlets were primary sources of this content, often employing 'transition fuel' rhetoric to legitimize the project despite its environmental impacts and legal challenges.

The project utilizes paleotempestology—analyzing sediment cores from lagoons, stalagmite isotopic records, tree rings, and corals—to reconstruct past tropical cyclone activity. Key findings indicate that higher sea surface temperatures in the Atlantic correlate with increased hurricane activity, with notable peaks during the Medieval Warm Period (AD 900-1100) and since 1980. The research also identifies an inverse phase relationship in hurricane landfalls between Central America, the Eastern Caribbean, and the US East Coast, suggesting that the Intertropical Convergence Zone (ITCZ) and tropical anticyclones are critical drivers of coastal risk. Additionally, the study expanded its scope to the Pacific coast of Mexico, identifying an extreme event in Baja California Sur approximately 500 years ago.

The project utilizes paleotempestology—analyzing coastal lagoon sediments, stalagmites, tree-rings, and corals—to reconstruct past hurricane activity in the Caribbean and Mexico. Key findings link increased hurricane activity to warmer sea surface temperatures and specific climate patterns like the Atlantic Multidecadal Oscillation (AMO) and El Niño-Southern Oscillation (ENSO). The research identifies peaks in activity during the Medieval period (AD 900-1100) and since 1980, while also noting an anti-phase relationship in landfall activity between Central America and the eastern Caribbean/U.S. East coast. Additionally, the study assesses coastal vulnerability in the U.S., noting millions of people live in low-elevation areas.

The document is an amicus curiae application and submission in the case of Odyssey Marine Exploration, Inc. v. United Mexican States. The applicants argue that the Don Diego Project, which involves dredging 91 thousand hectares of the Gulf of Ulloa seabed to extract phosphate rock, would cause irreversible ecological damage and violate human rights. They contend that the Mexican State's decision to deny the environmental permit is supported by the precautionary principle and obligations under UNCLOS, the Rio Declaration, and various human rights treaties, including the ICESCR and the American Convention on Human Rights.

The amicus curiae brief argues that the Mexican state was obligated to deny the environmental permit for the Don Diego project due to severe risks to the marine ecosystem of the Golfo de Ulloa and the human rights of local fishing communities. The authors contend that the project, which involves dredging 91,000 hectares of the seabed to extract 7 million tons of phosphate rock annually, would cause irreversible biodiversity loss and contaminate the area with radioactive elements like uranium and thorium. They assert that the precautionary principle and international treaties—including the UN Convention on the Law of the Sea and the American Convention on Human Rights—mandate the protection of the environment and the right to work and health for the 128 families of the Puerto Chale Cooperative and other regional residents.

The document outlines the increasing likelihood of exceeding the 1.5°C warming threshold and the resulting interest in 'emergency' options like solar radiation modification (SRM) and carbon dioxide removal (CDR). It highlights a critical lack of formal international and national governance for SRM, noting a specific instance in Mexico where a private US company conducted unauthorized aerosol experiments. The text details efforts by IAI, CEPAL, and C2G to raise awareness and build regional governance frameworks in Latin America and the Caribbean to manage these climate interventions.
