Climate Awareness for Living in Indiana
Our changing climate is rapidly increasing the need to be ready and resilient against natural disasters. Some of the most common threats in Indiana include flooding and excessive heat in the summer, and drastic temperature swings that can bring polar vortexes during the winter season. Review some of the resources below to stay up-to-date on Indiana's climate impacts and be prepared if an extreme weather event strikes.
Indiana Climate Change Impacts Assessment
The Indiana Climate Change Impacts Assessment was a statewide effort led by Purdue University and provides detailed reports on the effects of climate change on agriculture, health, ecosystems, urban spaces, and energy in Indiana. It aims to help residents and policymakers understand these impacts and adapt accordingly. Some of the key findings include the following:
-
Since 1895, Indiana’s average temperature has increased by 1.2°F. By mid-century, this could rise by 5°F to 6°F. Southern Indiana, for example, is expected to see up to 51 days per year above 95°F, compared to an average of 7 in the past, by mid-century. Such heat will particularly impact the health of vulnerable groups like children and the elderly.
-
Indiana’s annual precipitation has increased by 15% since 1895, with more rain falling during intense storms. Projections indicate that winters and springs will become 6-8% wetter by mid-century, especially in urban areas with combined sewer systems. This will lead to more frequent flooding and water contamination.
-
Indiana’s frost-free season now lasts 9 days longer than in the early 20th century, and could lengthen by 3.5 to 4.5 weeks by mid-century. While a longer season may boost crop productivity, some crops, like blueberries, require "chill hours" to break dormancy. It also extends the allergy season and creates favorable conditions for pests and invasive species.
-
The number of days below 5°F in northern Indiana is expected to decrease from 13 days historically to about 6 by mid-century. Warmer winters will reduce natural pest controls and increase risks from ticks, mosquitoes, and forest pests that previously were kept in check by colder winters.
Flood Preparedness
The Occupational Safety and Health Administration (OSHA)'s Flood Preparedness Page offers information on how to plan and respond to flood emergencies in the workplace. It includes guidance on evacuation plans, worker safety measures, training, and compliance with safety standards like HAZWOPER. The following takeaways are generalized to the population.
- Develop an evacuation plan that outlines specific procedures and routes.
-
Understand the terms—Flood Watch, Flash Flood Watch, Flood Warning, and Flash Flood Warning—and monitor NOAA Weather Radio or media for alerts.
-
Prepare emergency kits for shelter use and ensure supplies are accessible.
-
Regularly practice evacuation drills and update plans as needed.
Winter Weather Preparedness

OSHA's Winter Weather Preparedness Page provides guidance on protecting workers during severe winter conditions. It discusses training on cold stress, appropriate protective clothing, implementing engineering controls, and using safe work practices to minimize risks. The following takeaways are generalized to the population.
-
Prepare for winter weather by learning how to recognize cold stress symptoms, understanding first aid for hypothermia and frostbite, and knowing how to handle common winter hazards like icy roads, slippery walkways, and power outages.
-
Use space heaters safely and insulate windows and doors to reduce drafts. When possible, create wind barriers around outdoor areas, such as porches, to reduce exposure to wind chill.
-
Plan outdoor activities for the warmest part of the day, limit time spent outside, and take breaks in warm spaces. Dress in layers, stay hydrated with warm drinks, and monitor yourself and others for signs of cold-related stress.
-
Dress in multiple layers with an inner moisture-wicking layer, an insulating middle layer, and an outer layer for wind and water resistance. Cover extremities with insulated gloves, hats, and waterproof boots.
Extreme Heat Preparedness

OSHA's Heat Stress Guide provides information on recognizing, preventing, and treating heat-related illnesses such as heat stroke, heat exhaustion, and heat cramps. The guide also outlines engineering and administrative controls that can be used to minimize heat stress risks in hot work environments. The following takeaways are generalized to the population.
-
Be aware of environments prone to heat stress (e.g., kitchens, outdoor work in summer) and personal factors like health, hydration, and acclimatization.
-
Drink water regularly, even if you’re not thirsty. Avoid alcohol and caffeinated drinks in hot conditions.
-
Dress appropriately. Wear lightweight, loose-fitting clothing, and consider sun protection like hats or shades.
-
Rest in shaded or cool areas, especially during peak heat hours. Limit strenuous activities.
-
Learn symptoms of heat exhaustion (e.g., nausea, weakness) and heat stroke (e.g., confusion, dry skin). Seek immediate medical help if needed.
