New York City Climate Projections: Extreme Events and Sea Level Rise

This report includes updated changes in extreme events (e.g., hot days, days with heavy rainfall, heat waves) for the 2030s, 2050s and 2080s; and sea level rise projections for the 2030s, 2050s, 2080s, 2100 and 2150 for the New York City region, based on those developed for the IPCC 6th Assessment report. The sea level rise projections are based on the CMIP6 models and SSP framework, and also incorporate advances in process understanding, improved and lengthened observational records, and improved ice-sheet modeling.

The New York City Panel on Climate Change (NPCC) started in 2009 and was codified in Local Law 42 of 2012 with a mandate to provide an authoritative and actionable source of scientific information on future climate change and its potential impacts.

The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change.
