6. Since 2010, Philadelphia has experienced:
The snowiest winter on record
The two warmest summers on record
The most days over 90 degrees on record
The warmest July on record
The wettest day on record
The wettest month on record
The two wettest years on record
Two hurricanes
And a derecho.

Seems like climate change impacts are far away, in other places, but here’s what’s been happening here.

Decision point info. So what will this mean in practical terms to guide adaptation planning and risk reduction measures?
What are the City’s risks, responsibilities and levers?
Consequences of Changes in Precip
More flooding (river, flash, and local)
Greater flood risk from storm surge
Higher groundwater Table
Public health impacts (largely vector – think bugs)
Transportation delays and disruptions
Changes in water quality
change in salt levels
erosion from storm events
Consequences of a hotter climate
Air quality decreases, which increases respiratory illnesses
Increase demand for cooling centers
Increase demand for outdoor rec
Longer runways at airports
Increase in energy use and peak demand
Early closures of offices
Warmer rivers and streams
Consequences of sea level rise
Change in water quality – salt line moves upstream
Greater risk of storm surge
Change in flood insurance rate maps
Higher groundwater table
