Climate change poses a significant threat globally, and for small island nations like Barbados, it presents unique challenges and vulnerabilities. This section explores the fundamentals of climate change as they pertain to Barbados, providing an overview of its effects, historical climate data, and the particular vulnerabilities faced by Small Island Developing States (SIDS) like Barbados.

Overview of Climate Change Effects

Climate change refers to the long-term alteration of temperature and typical weather patterns in a place. While climate change is a global phenomenon, its effects are often felt more acutely in island nations due to their geographical and socio-economic contexts. In Barbados, the impacts of climate change manifest in diverse ways, including rising sea levels, increased frequency and intensity of hurricanes, and shifts in precipitation patterns.

One of the most pressing concerns is the rise in sea levels. According to the Intergovernmental Panel on Climate Change (IPCC), sea levels are projected to rise between 0.3 and 1.1 meters by the end of the century, depending on global greenhouse gas emissions scenarios. For Barbados, this means that low-lying coastal areas are at risk of flooding, threatening infrastructure, freshwater resources, and ecosystems. Coastal erosion, exacerbated by higher sea levels and more intense storms, further endangers the island’s beaches and coastal habitats, which are crucial for tourism and local fisheries.

Additionally, the frequency and intensity of tropical storms and hurricanes are expected to increase, with studies suggesting that warmer ocean temperatures contribute to more powerful storms. Barbados, situated in the Atlantic hurricane belt, is particularly vulnerable to such events. Hurricanes not only cause immediate destruction but also have long-term impacts on the island's economy, particularly in the tourism sector, which is a significant source of revenue for the nation.

Another critical effect of climate change is the alteration of local ecosystems. Changes in temperature and rainfall patterns threaten biodiversity, impacting both terrestrial and marine ecosystems. Coral reefs, which are vital for marine biodiversity and coastal protection, are under stress due to warmer water temperatures, leading to coral bleaching. This phenomenon not only diminishes the reefs' health but also affects the numerous species that rely on them for habitat and food.

Historical Climate Data of Barbados

To understand the current and future impacts of climate change, it is essential to examine historical climate data. Barbados has a tropical maritime climate, characterized by a wet season from June to November and a dry season from December to May.
