Potential climate change effects, risks, and vulnerabilities:
- Puerto Rico is expected to warm faster than the global average, with increases in both mean and extreme temperatures, including more days per year over 95°F and nights warmer than 85°F.
- Rainfall will decrease, particularly in the wet season, with more frequent dry days.
- The frequency of moderate extreme precipitation (over 1 inch of rain) will decrease, while more extreme precipitation (over 3 inches of rain in a day) will be more common.
- Projected temperature changes are large enough to affect temperature sensitive crops, species, and ecosystems, while the combined effects of changes in temperature and precipitation are likely to increase the demand for energy, the risk of water stress and drought, and the risk of impacts from heavy rainfall events .
