While much of Iowa is still suffering from this summer’s drought, which left Iowa’s farmers with $1 billion in crop damages, a new Environment Iowa Research & Policy Center report finds that weather-related disasters are already affecting hundreds of millions of Americans, and documents how global warming could lead to certain extreme weather events becoming even more common or more severe in the future.
Global warming is happening now and its effects are being felt in the United States and around the world. Among the expected consequences of global warming is an increase in the heaviest rain and snow storms, fueled by increased evaporation and the ability of a warmer atmosphere to hold more moisture.
Industrial facilities continue to dump millions of pounds of toxic chemicals into America’s rivers, streams, lakes and ocean waters each year—threatening both the environment and human health. According to the U.S. Environmental Protection Agency (EPA), pollution from industrial facilities is responsible for threatening or fouling water quality in more than 14,000 miles of rivers and streams, more than 220,000 acres of lakes, ponds and estuaries nationwide.
Weather disasters kill or injure hundreds of Americans each year and cause billions of dollars in economic damage. The risks posed by some types of weather-related disasters will likely increase in a warming world. Scientists have already detected increases in extreme precipitation events and heat waves in the United States, and the Intergovernmental Panel on Climate Change recently concluded that global warming will likely lead to further changes in weather extremes.
By adopting a suite of clean energy policies at the local, state and federal levels, the United States could curb emissions of carbon dioxide from energy use by as much as 20 percent by 2020 and 34 percent by 2030 (compared with 2005 levels).
