New York City must prepare for higher temperatures, more rain and an increased risk of coastal flooding in the coming decades as a result of global climate change, an advisory panel said on Tuesday.
The panel, formed by Mayor Michael R. Bloomberg to study the potential effects of global warming on the city, said that mean annual temperatures in New York could increase by up to 3 degrees and the average sea levels rise by 2 to 5 inches by the 2020s. By the 2080s, temperatures could increase by up to 7 ½ degrees, and sea levels could rise 12 to 23 inches by the end of the century, the panel said.
Cynthia Rosenzweig, a senior research scientist at the Goddard Institute for Space Studies at Columbia University, who is the chairwoman of the panel, acknowledged that it was difficult to make predictions about the effects of climate change on specific regions and that climate models that attempt to do so carried uncertainties.
