Top Climate Change Risks: Precipitation, Heat, Flood

People in New York will experience especially increased risks from precipitation, heat, and flood due to climate change over the next 30 years. These risks, through 2050 and beyond, may change depending on how much we reduce emissions in the near future.

ClimateCheck Risk Ratings measure the risk posed by a hazard on a 1-100 scale, using historical conditions and projected scenarios through 2050. Climate change has complex, interacting local and large-scale effects that impact everyone on Earth, and a low risk rating does not mean no exposure to impacts from that hazard. See how we measure risk.

• For heat, Watertown has the lowest risk and New York has the highest risk.
• For precipitation, Rochester has the lowest risk and Long Beach has the highest risk.
• For drought, Long Beach has the lowest risk and Syracuse has the highest risk.
• For fire, Buffalo has the lowest risk and Poughkeepsie has the highest risk.
• For flood, New York has the lowest risk and Long Beach has the highest risk.

To measure precipitation risk, we look at the amount of precipitation that falls in 48-hour periods exceeding a location-specific threshold, and how many times this happens per year. A precipitation threshold is based on the top 1% of rainiest days per year for a location.

Historically, Long Beach experienced an average of 1.8 inches of rain about 10 times per year. In 2050, it is projected to experience an average of 1.8 inches of rain about 12 times per year.

Historically, Rochester experienced an average of 1.1 inches of rain about 10 times per year. In 2050, it is projected to experience an average of 1.0 inches of rain about 14 times per year.

Coastal flood hazards include storm surge, when strong winds push water to shore, and rising sea levels due to climate change. The rate of sea level rise varies along the coast. Rising seas contribute to greater instances and spread of high-tide flooding, when high tides inundate land, and greater potential storm surge depths.



Drought risk is based on water stress, which is a projection of how much of the water supply will be taken up by human demand.

In the figure, the blue bars represent the available water every 10 years from 2020-2060, and the orange bars represent demand. The drought risk rating is based on the ratio of supply to demand and the projected change in this ratio. Lower supply and higher demand correspond to a higher score.
