Climate change in Indiana encompasses the effects of climate change, attributed to man-made increases in atmospheric carbon dioxide, in the U.S. state of Indiana.

According to the United States Environmental Protection Agency, "Indiana's climate is changing. Most of the state has warmed about one degree (F) in the 20th century. Floods are becoming more frequent, and ice cover on the Great Lakes is forming later or melting sooner. In the coming decades, the state will have more extremely hot days, which may harm public health in urban areas and corn harvests in rural areas".^[1] In May 2019, The Kansas City Star noted that although it was not yet possible to say whether climate change was contributing to the increasing number of tornadoes in the region, "the band of states in the central United States ... that each spring are ravaged by hundreds of tornadoes — is not disappearing. But it seems to be expanding", resulting in a higher frequency of tornadoes in states including Indiana.^[2]

Indiana is one of the ten states that produce half of all greenhouse gas emissions in the US.^[3]
