Tropical savanna climates are most commonly found in Africa, Asia, Central America, and South America. The climate is also prevalent in sections of northern Australia , the Pacific Islands, in extreme southern North America in south Florida , and some islands in the Caribbean .
The U.S. Virgin Islands have a tropical savanna climate, with warm, dry winters, and rainy summers (Köppen Aw), typical of the Caribbean. The wet season is from May to October. In 2015, the Wall Street Journal reported that U.S. territories such as Puerto Rico are the areas of the U.S. most vulnerable to climate change. [7]
In addition, climate change impacts oceanic currents and sea levels, further altering fish distributions and habitats. Furthermore, ocean acidification , resulting from increased CO2 levels, compromises the ability of shellfish and corals to form shells and skeletons, further endangering marine ecosystems and the communities that depend on them.
The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between 90–150 centimetres (35–59 in) per year. [1] Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions.
The Köppen climate classification is the most widely used climate classification system. [2] It defines a tropical climate as a region where the mean temperature of the coldest month is greater than or equal to 18 °C (64 °F) and does not fit into the criteria for B-group climates, classifying them as an A-group (tropical climate group).

As with other regions of the country, climate change is already upending weather patterns in the ... resulting in an additional 200 to 550 premature deaths in the region per year by 2050.” ...
[2] [3] Climate change represents long-term changes in temperature and average weather patterns. [4] [5] This leads to a substantial increase in both the frequency and the intensity of extreme weather events. [6] As a region's climate changes, a change in its flora and fauna follows. [7]
[7] [8] [9] Climate change's impacts on tropical cyclones and sea level rise also affect regions of the country. Cumulatively since 1850, the U.S. has emitted a larger share than any country of the greenhouse gases causing current climate change, with some 20% of the global total of carbon dioxide alone. [10]
