Paul Knight, senior lecturer in meteorology at Penn State, compiled rainfall data for Pennsylvania from 1895—when recordings were first made—to this year. He says there has been an increase of 10 percent of rainfall during the past century. Until the 1970s, the average rainfall throughout the state was about 42 inches. Beginning in the 1970s, the average began creeping up. “By the 1990s, the increase was noticeable,” he says. The three wettest years on record since 1895 were 2003, 2004, and 2011. The statewide average was 61.5 inches in 2011, the year of Tropical Storm Lee, which caused 18 deaths and about $1.6 billion in damage in Alabama, Louisiana, Mississippi, and Texas, and devastating flooding in New York and Pennsylvania, especially along the Susquehanna River basin.
Dr. Harvey Katz, of Montoursville, Pa., extended Knight’s data analysis for five decades. Dr. Katz predicts an average annual rainfall of about 55 inches, about 13 inches more than the period of 1895 to 1975. The increased rainfall isn’t limited to Pennsylvania, but extends throughout the Mid-Atlantic and New England states.
Both Knight and Dr. Katz say floods will be more frequent. The industrialization and urbanization of America has led to more trees being cut down; the consequences are greater erosion and more open areas to allow rainwater to flow into streams and rivers. Waterway hazards, because of flooding and increased river flow, will cause additional problems. Heavy rains will cause increased pollution, washing off fertilizer on farmlands into the surface water supply, extending into the Chesapeake Bay. Sprays on plants and agricultural crops to reduce attacks by numerous insects, which would normally stay localized, will now be washed into streams and rivers, says Knight.
Pollution will also disrupt the aquatic ecosystem, likely leading to a decrease in the fishing industry because of increased disease and death among fish and other marine mammals, says Dr. Katz.
Another consequence of increased rainfall is a wider spread of pollution from fracking operations, especially in the Marcellus Shale.
