Decline in crop yields: How climate change has affected Indiana

The latest United Nations Intergovernmental Panel on Climate Change (IPCC) report is yet another reminder of the dire effects of climate change. While climate projections often look to the future when discussing the worst impacts of climate change, we are in fact already experiencing its effects across the United States. To better understand how climate change is impacting the country, Stacker compiled a list of the impacts of climate change in every state, using local and national news stories, government reports, and scientific journal articles.

While these impacts are weather-related—for example, heat waves, droughts, or storms—individual weather events cannot be attributed to climate change on their own. Rather, it is when these events are seen within larger trends that they can be understood as part of a pattern that has come out of the changing climate.

Indiana: Decline in crop yields

The Indiana annual crop summary released in January 2020 showed that changing weather patterns, which can be attributed to climate change, affected the production of the state's most important crops. In 2019, according to the U.S. Department of Agriculture, near-historic levels of precipitation caused a decline in corn and soybean production. This could potentially cost farmers hundreds of millions of dollars a year.

Across the country, there are trends of rising temperatures, storms of increasing frequency and severity, and more erratic precipitation patterns, causing disruptions to the food systems and sometimes even resulting in death. While the U.S. government has set a target to reduce greenhouse gas emissions by at least 50% by 2030, it is clear that the climate emergency is already taking place, and along with emissions reductions, mitigation of the impacts of climate change must be prioritized as well.

Michigan: Flooding in Detroit

During the summer of 2021, extensive flooding from extreme weather events had dire impacts in Detroit. Along with the weather itself, the failing infrastructure in the city led to people having to sometimes dig human waste out of their own basements. Unfortunately, the areas that are often hit hardest by climate change are poorer areas with Black and brown residents. "Black and brown communities are bearing the brunt of heat waves, paying disproportionately higher costs on failing infrastructure," Michelle Martinez, the acting executive director and founding member of the Michigan Environmental Justice Coalition, said in an interview with Michigan Radio's Stateside.

Ohio: Changes to Lake Erie

According to the 2018 Fourth National Climate Assessment report, climate change has been affecting the Great Lakes, including Ohio's Lake Erie. Due to warming in the Midwest, there is an increase of lake-effect snow, and in the future, as temperatures warm further, that could shift to rain. In addition, there are increased lake surface temperatures leading to decreased ice coverage, which could actually lead to more snow. Lake Erie is also seeing more algae blooms due to the increased temperature. In 2014, cyanobacteria from an algae bloom polluted the drinking water of Toledo, Ohio.
