Downscaling Climate for Indiana

Modeling climate scenarios for Indiana

Under future emission scenarios, Indiana in the 2050s would have a climate similar to the current climates of more southern states. Graphic from the INCCIA. Courtesy of Scott Robeson.

Climate downscaling—a computational technique that uses information at large scales to make projections at local scales—plays a key role in projecting future climate scenarios. IU Assistant Professor Ben Kravitz and his collaborators are building a range of climate scenarios for Indiana using climate projections provided by the Intergovernmental Panel on Climate Change (IPCC).

The IPCC produces global climate predictions about every five years based on hypothetical scenarios of human activity in the future. These projections play a key role in guiding countries around the world as they develop plans to mitigate and prepare for environmental change. Using IPCC data, Kravitz’s team is focused on developing an efficient downscaling approach for Indiana that will account for applications essential to the well-being of the state, including health, hydrological, agriculture, clean energy, and other social impacts.

Results will supply Indiana communities, businesses, and policymakers with a baseline for future climate scenarios in the state that can be used to plan for environmental change.
