Made up of leading climate and social scientists

All projections subject to rigorous peer review

Focus on climate risks:

• Temperature • Precipitation • Changes in sea level • Extreme events

New York City Panel on Climate Change

By the 2050s:4.1oF to 5.7oF increase in average temperature 4% to 11% increase in average annual precipitationSea levels likely to rise 1‐2 ft.; maybe 2½ ft.

By 2100:High‐end projections may reach 6 ft.

By the 2050s:Number of days in NYC above 90⁰ could triple

Even today:100‐year floodplain expanded by 17 square miles (51%) citywide; 2.3 ft. average increase in 100‐year flood elevations; will increase with further sea level rise; now encompasses 71,500 structures

The NYC Panel on Climate Change (NPCC) projects increased chronic climate hazards…

…and increased impact from extreme weather events.

Climate Change / 21st Century Threats…And grapple with the impacts of climate change on our city.

Multi‐Family Study Major takeaways

UNIVERSE OF BUILDINGS AT RISK: Multifamily and mixed use structures in the high‐risk floodplain contain 81% of housing units, with number of structures growing by 30% in 2013 PFIRM and 40% by 2020s. 

1

COVERAGE AND COSTS: NFIP insures 42% of multifamily and mixed‐use structures in the high‐risk floodplain (20% of regulated units), but due to coverage limits many structures are unable to secure meaningful coverage.

2

PERCEPTIONS OF INSURANCE AND RISK: Owners and managers are not well‐informed about their flood insurance policies, and there is confusion within the brokerage industry. There is little to no incentive to mitigate to offset costs.
