According to the draft ClimAID report
released by the New York State Energy and Research Development Authority (NYSERDA) in 2010, Bethlehem and the upstate New York region are predicted to be impacted by climate change through:
- Increased average temperatures
- Increased frequency of extreme heat days (days over 90° F)
- Increased average annual precipitation and changes to the annual precipitation patterns
- Increased frequency of extreme precipitation events (days with over 1” of precipitation)
- Increase in the frequency and severity of storms
- Sea level rise along the tidal Hudson River
The effects of climate change to human health, infrastructure, and the economy in the region are significant. With higher temperatures, residents would experience higher cooling costs and increased risks of heat stroke, especially for at risk populations such as seniors and low income families. Higher annual temperatures and more frequent extreme heat days result in poor air quality which increases the risk of respiratory illness, especially for those who suffer from in asthma and allergies.
Warmer temperatures are also more hospitable for mosquitoes and bacteria, leading to higher incidences of vector-borne diseases.
Changes to precipitation are likely to result in more rain and snowfall in winter and droughts in summer. More of the precipitation will come as heavy downpours, which could lead to more flooding, sewer overflows, power outages, and damages to property and infrastructure.
As the region’s climate changes, local ecosystems will also be impacted. Spruce, fir, hemlock, and maples would die off and migrate to northern climes. Pests previously controlled by cold winters would proliferate and destroy urban street trees as well as large swathes of forest. Fisheries and wildlife would die or migrate to colder climates. Non-native species would replace native species. These impacts would change the economy and character of the region.
Preparation for Change
Due to the significant amount of greenhouse gases already in the atmosphere and the inertia of the system, some level of change is inevitable, despite efforts to reduce emissions. Therefore, it is important for the town and the region to prepare for climate change and enhance resiliency to a wide range of impacts. Once completed, Bethlehem’s GHG inventory and climate action plan will help the town prepare for the projected impacts and effects of a changing climate.
