Paleotempestología de la región caribeña: un estudio multi-proxy de la variabilidad espacial y temporal de la actividad de los huracanes en el Caribe en múltiples sitios
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.

Hurricane Helene Exposes Insurers’ Climate Hypocrisy
The document examines the intersection of the climate crisis and the US insurance system, focusing on the aftermath of Hurricane Helene in North Carolina. It highlights a disconnect where insurers seek significant rate hikes—up to 99% in some coastal areas—despite historical profitability, while many homeowners remain uninsured for flood damage. The authors argue that the insurance industry exacerbates the climate crisis by investing over $500 billion in fossil fuel-related assets and underwriting fossil fuel projects, thereby profiting from the drivers of the extreme weather that leads to higher insurance claims.

People Exposed to Climate Change: June-August 2024
The report finds that June through August 2024 was Earth's hottest season on record, with human-induced climate change significantly increasing the frequency and intensity of extreme heat worldwide. Using the Climate Shift Index (CSI), the analysis shows that one in four people experienced temperatures made at least three times more likely by climate change every day of the season. Global exposure peaked on August 13, 2024, affecting 4.1 billion people. The average person experienced 17 additional 'risky heat days' (temperatures above the 90th percentile) due to climate change. Over 2 billion people experienced 30 or more such days, with extreme concentrations in the Caribbean, Western Asia, Micronesia, Northern Africa, and Southern Europe. Additionally, 72 countries experienced their hottest June-August period since 1970, and 180 Northern Hemisphere cities faced dangerous extreme heat waves that were, on average, 21 times more likely due to human-caused warming.

The Climate Crisis Domino Effect
The report examines how the increasing frequency and severity of climate-driven disasters lead insurance companies to raise premiums or withdraw coverage, particularly in high-risk areas of the US. This process creates a 'domino effect' where the lack of affordable insurance makes homes unmortgageable, reduces property values, and increases homelessness. The authors highlight a cycle where insurers profit from these increases and reinvest in fossil fuels, further exacerbating the climate crisis. The document warns that widespread mortgage defaults and the devaluation of lender security could lead to a systemic financial crisis with global implications.
