Climate change refers to any significant change in measures of climate, such as temperature, precipitation, wind, and other weather patterns, that lasts for decades or longer. The world’s climate is showing signs of a shift, becoming warmer, with more precipitation and weather extremes. Potential effects of this climate change are likely to include more variable weather, stronger tropical cyclones, stronger and longer heat waves, more frequent heavy precipitation events, more frequent and severe droughts, extreme weather events such as flooding, rises in sea level, and increased air pollution.        More »
