Pennsylvania's Changing Climate: What It Means For You

DEP Climate Change.JPGWill Pennsylvania's poultry inventory double in 40 years? The state average annual temperature has increased 1.8 degrees Fahrenheit since 1901 and is on track to rise another 4.9 degrees in about 40 years.  This is creating increased swings of extremes in heat and rainfall that will affect farming, water pollution, our health, the power grid, and other areas.

See this storymap  to learn how greenhouse gas emissions are changing our climate, the projected impacts, and what state and local governments and a growing number of partners are doing to slow down the thermometer to protect Pennsylvania.
