Use this page to learn how climate change is affecting people in Pennsylvania.
Then, use our tool to check your address for local and property-specific heat, precipitation, drought, fire, and flood risk.
People in Pennsylvania will experience especially increased risks from precipitation, heat, and drought 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.
Of these top cities in Pennsylvania, the city with the highest overall risk is Philadelphia. The city with the lowest overall risk is Altoona.
Among the lower 48 states, Pennsylvania's highest ranking is #9 for storm risk.
Rhode Island and New York rank highest for storm risk Nevada and Arizona rank lowest for storm risk
Pennsylvania ranks #43 for fire risk.
Highest fire risk: Oklahoma and Wyoming
Lowest fire risk: Maine and Vermont
See our fire ranking methodology.
Pennsylvania ranks #18 for drought risk.
Highest drought risk: Nevada and California
Lowest drought risk: Mississippi and Vermont
Pennsylvania ranks #24 for heat risk.
Highest heat risk: Louisiana and Mississippi
Lowest heat risk: California and Oregon
Pennsylvania ranks #11 for flood risk.
Highest flood risk: Arizona and West Virginia
Lowest flood risk: Utah and Nevada
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, Scranton experienced an average of 1.4 inches of rain about 10 times per year. In 2050, it is projected to experience an average of 1.3 inches of rain about 13 times per year.
Historically, York experienced an average of 1.4 inches of rain about 11 times per year. In 2050, it is projected to experience an average of 1.3 inches of rain about 13 times per year.
An extremely hot day in Pennsylvania depends on your location: 93ºF is extremely hot for Philadelphia, while 86ºF is considered extremely hot for Erie. This is based on historical maximum temperatures on the top 2% of days in an average year.
The frequency of very hot days is increasing. On average, someone in Pennsylvania will experience about 40 extremely hot days in 2050.
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.
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.
Mitigating climate change—by eliminating our emissions into the atmosphere and reducing our strain on the environment—and adapting to our changing planet are both vital to our well-being.

Green infrastructure is a category of nature-based solutions to increasing precipitation. Find resources for individuals and municipalities through the EPA's Soak Up the Rain initiative.
Planting trees and vegetation helps reduce extreme heat in urban environments. Cool Pavements can also help urban heat islands. Search the Heat Island Community Actions Database to see what some municipalities have been doing to reduce extreme heat risk.
