July milk production in the Pittsburgh region could decline by as much as 20 percent by the end of the century if global warming persists, according to a study conducted by the Union of Concerned Scientists. Heat stress already causes livestock losses of more than $50 million annually in Pennsylvania.
How Will Climate Change Affect Our Economy?
Some experts predict climate change could reduce global gross domestic product by as much as 5 percent per year.
More storms producing more rainfall have the potential to damage crops if not delay planting. More frequent and more severe droughts, meanwhile, could devastate a region’s agricultural industry. All of this could reduce yields significantly and increase the cost consumers pay for groceries.
Rising temperatures, meanwhile, are expected to trigger an earlier onset and a possible extended spring allergy season. Nearly 40 million Americans suffer from hay fever, causing an estimated 4 million lost days of work and school each year, reducing productivity and adding to labor costs.
Pittsburgh, however, is rapidly becoming a leader in the “green economy.” Consuming its abundance of natural resources enabled Pittsburgh to become a global economic force. Today Pittsburgh’s ability to protect its environment is once again putting the city and its businesses on the map.
