Building the Knowledge Base for Climate Resiliency: New York City Panel on Climate Change 2015 Report

Report Contents

Documents observed climate changes and provides climate projections for the first time through 2100 for temperature, precipitation, and sea level rise

Presents new maps for the coastal flood risks through 2100 for the current 100-year (1% annual chance of occurrence) and 500-year (0.2% annual chance of occurrence) coastal flood events

Characterizes future coastal flooding through enhanced dynamic flood inundation modeling that includes the effects of sea level rise

Provides a review of key issues related to climate change health risks relevant to the citizens of New York City

Develops a process for enhancing a New York City Climate Resiliency Indicators and Monitoring System

Key Points

NPCC 2015 projections are broadly consistent with NPCC 2010 projections. For the first time, they are extended through the year 2100. 

The science base has been broadened to include an increased number of global climate models, new sea level rise methodologies, and dynamic coastal flood modeling. 

A new topic covered in the report is public health. New York City faces potential health risks related to two principal climate hazards: increasing temperatures/heat waves and coastal storms with flooding.

NPCC 2015 provides the ‘best available data’ for use in the New York metropolitan region, as recommended by President Obama’s recent (1/30/2015) Executive Order.
