New York State's Changing Climate Figure Gallery

Two maps of New York State, each with an inset map of New York City. The top map is colored and labeled by assessment region and overlaid with county divisions. The bottom map shows the locations of 19 stations with temperature, precipitation, and extreme event data, eight stations with temperature and precipitation data, three stations with observed and projected sea level data, and one station with observed sea level data. The bottom map is overlaid with assessment region boundaries and labels.
