Effects of Global Warming

Though it is difficult to connect specific weather events to global warming, an increase in global temperatures may in turn cause other changes, including glacial retreat and worldwide sea level rise ( http://en.wikipedia.org/wiki/Global_Warming). Changes in the amount and pattern of precipitation may result in flooding and drought (http://en.wikipedia.org/wiki/Global_Warming). There may also be changes in the frequency and intensity of extreme weather events (http://en.wikipedia.org/wiki/Global_Warming). Other effects may include changes in agricultural yields, reduced summer streamflows, species extinctions, and increases in the range of disease vectors (http://en.wikipedia.org/wiki/Global_Warming).
