The report finds that human-induced climate change has reduced rainfall in Jamaica by approximately 6% and in Puerto Rico by about 9%. These changes have increased the likelihood of severe effective precipitation events in both regions compared to a pre-industrial climate. The study highlights that warmer temperatures intensify drought severity through higher evaporation, making the 2026 early wet season rainfall deficits more frequent and severe.

Hurricane Beryl, the earliest Category 5 hurricane on record, was fueled by ocean temperatures 2°–3°F warmer than normal, conditions made 100–400 times more likely by human-caused climate change.

Montserrat has reached 50 percent renewable energy installed capacity through the installation of a 750 kW solar system and 1 MWh battery storage, which powers 300 households. The project, supported by RMI, focused on hurricane resilience—designing for 180 mph wind speeds—and equity, as the utility-owned facility allows diesel savings to be shared among all customers via reduced fuel surcharges. While the island aims for 100 percent renewable electricity by 2030, further progress is constrained by the size of the economy and requires continued grant funding.

The Reefs at Risk Caribbean project workshop focused on improving a threat assessment model for coral reefs using proxy indicators. Key discussions centered on refining data for coastal development, watershed-based pollution, overfishing, and coral bleaching. Participants recommended incorporating higher-resolution data, adjusting population density metrics for fishing pressure, and treating coral bleaching and disease as separate analysis layers rather than integrated threat model components. The workshop also addressed the need for better mapping of Marine Protected Areas (MPAs) and the economic valuation of reefs.
