Effects of Climate Change on Narragansett Bay
The effects of climate change are occurring on a global scale. These changes will only accelerate as carbon dioxide, the primary greenhouse forcing continues to accumulate in the atmosphere. In addition, numerous positive feedback loops resulting from warming temperatures will exacerbate the amount and rate of warming. At the start of the Industrrial Revolution, the level of atmospheric carbon dioxide was 280 ppm. Today, carbon dioxide levels have risen to 394 ppm. The abstact below, briefly details some of the effects rising carbon dioxide levels have had on Narragansett Bay. These data provide a glimpse of the rapidly changing world our children will inherit unless we act responsibly and immediately. jj

Abstract
The objective of this paper is to examine the impacts of global climate change on Rhode Island's coastal ecosystems. Average annual air temperature in Rhode Island has increased by 1.7 °C since 1880, water temperatures of Narragansett Bay have increased by 1.2 °C since 1950, precipitation increased 27% between 1895 and 1999, and sea level rose 0.13 m between 1931 and 2007. We can already see the effects of these climatic changes on the Narragansett Bay ecosystem, including ecological changes in the Bay's food web from phytoplankton and Zooplankton to fish, e.g., changes in phenology of seasonal phytoplankton blooms and dominant fish species (e.g., Pseudopleuronectes americanus [Winter Flounder]). These climatic changes have increased freshwater inputs and the concomitant pollutant loads into the Bay. Rising sea level has contributed to ongoing erosion of the coast and has put waterfront homes at increased risk. It is imperative to continue monitoring these effects.
