According to a new report from Penn State University, dangerously high summer temperatures, more severe storms, an increased threat of some diseases carried by insects and drastic changes to agriculture and water quality are becoming facts of life for state residents.
“The scientific data is clear: climate change is happening, and there will be impacts to PA,” said lead author James Shortle, Ph.D., a professor of agricultural and environmental economics and director of the Environment and Natural Resources Institute, in a press statement from DEP. “The effects of climate change will be felt across all parts of PA – agriculture, human health, water quality, energy, even outdoor recreation will be affected.”
The 2015 Climate Impacts Assessment makes the issue more explicit than the typical scientific report. The report notes that by 2050, Philadelphia’s climate will be similar to current-day Richmond, VA, and Pittsburgh’s will be similar to current-day Washington, DC or Baltimore, MD. By 2050, it is expected that PA will be 5.4 degrees warmer than it was in 2000. The report found that PA has warmed 1.8 degrees in the past 110 years, and the trend will continue at an accelerated rate.
The report, researched with the support of a Penn State multidisciplinary team, is the second update from the DEP meeting a 2008 directive from the legislature to study potential impacts of global climate change in PA.
“This report shows that climate change is reality and it will get worse, and it will affect key sectors of the economy, our health, and our quality of life,” said DEP Secretary John Quigley in the release. “We must respond to this challenge, and do so in a way that strengthens PA’s economy and improves the environment we live in. The entire state will experience the effects, and we must all take note of the consequences of our changing climate as detailed by Dr. Shortle and his colleagues.”
Some key concerns raised in the study are:
- Climate change could worsen air quality through increased pollen concentration, mold concentration, and ground-level ozone, causing longer allergy seasons, aggravating asthma, and increasing mortality among at-risk populations;
- Diseases like West Nile virus and Lyme disease could increase due to more favorable conditions for mosquitoes and deer ticks;
- Increased precipitation in many parts of the state could lead to higher flood risks and threaten safe drinking water supplies;
- Warmer temperatures will bring more favorable conditions for agricultural pests like weeds and insects; and
- Severe storms – strengthened by warmer temperatures – could affect reliable electric service and threaten current electricity infrastructure.
However, some changes will be positive, according to the DEP, including longer growing seasons and more tolerable temperatures for crops not currently grown in PA offer new opportunities for the state’s farmers.
