In 2008, New York City’s Mayor Bloomberg brought together leading climate scientists, academics and members of the private sector to advise the city on adapting to the impacts of climate change. This group, called the New York City Panel on Climate Change (NPCC), released its 2019 report in March. The report documents that local extreme weather events are becoming more frequent, longer lasting and more intense; temperatures in summer are getting hotter, and heavy downpours are increasing—changes that generally bear out the projections in the 2015 NPCC report.
