Climate Projections

Columbia University has generated a set of projections of physical climate variables such as temperature, precipitation, extreme events like heat waves and heavy storms, and sea level. These projections use the best available global climate models, downscaled for New York, and they cover multiple climate scenarios through the end of the 21st century—and in some cases, beyond. Final results and corresponding documentation are available for download below.
