Increasing levels of greenhouse gases, particularly during the past century, have been associated with rising global average temperatures, extreme temperatures, and heat waves. At the same time, other climatic changes in New York State (NYS) have included increased frequency and duration of extreme weather events and coastal storms, increased variability of temperature and precipitation, and higher average precipitation levels. These climatic changes have resulted in flooding events from extreme precipitation and rising sea level due to warmer waters and glacial and sea ice melt.
