New York City and climate change

In 1800, when the city still consisted primarily of Manhattan, the population of New York was only 60,515. After rapid growth in the 19th and 20th century the city now counts 8 million inhabitants. The projected population in Metropolitan New York (MET) in 2050 could be as high as 23 million residents.

New York City has a temperate, continental climate, with hot and humid summers and cold winters. Records show an annual average temperature between 1971 and 2000 of approximately 12.8°C. The annual mean temperature in New York City has risen by 1.4°C since 1900, although the trend has varied substantially. Between 1971 and 2000, New York City averaged 13 days per year with 25.4 mm (1 inch) or more of rain, 3 days per year with 50.8 mm (2 inches) or more rain, and 0.3 days per year with more than 101.6 mm (4 inches) of rain.
