Tackling Climate Change in Illinois

We're working for a future where people and nature thrive together.

The Nature Conservancy is working from global to local levels to tackle one of the biggest challenges of our time—climate change. In Illinois, our own actions can have an important impact on motivating climate action, reducing emissions and building resilience.

We are excited to collaborate with new and existing partners to move this work forward at the pace and scale necessary to accelerate ambition and efforts to meet shared climate change goals.

New Statewide Climate Assessment Released

The Illinois chapter recently released a first-of-its-kind, state-wide climate assessment. The report brought together the expertise of more than 40 scientists and technical experts to explain the most up-to-date information on how climate change is expected to affect Illinois. The writing was co-led by two members of TNC Illinois’ Science Advisory Committee, Dr. Don Wuebbles and Dr. Jim Angel, climate experts with years of expertise in atmospheric science. From TNC, Karen Petersen, the chapter’s climate change project manager, and Maria Lemke, director of conservation science, also played active roles in developing the report. Beyond providing a general overview of anticipated changes, the assessment explores predicted effects on hydrology, agriculture, human health and native ecosystems. These topics were selected because these sectors touch on many aspects of people’s lives and well-being.

Our Advocacy in Action

Illinois’ environment, public health and economy depend on strong climate and clean energy leadership at all levels of our government. And as our state grapples with the COVID-19 pandemic, families and businesses need a bold recovery effort to build a strong, equitable economy and healthier, more resilient communities.

40%

Over the past century, the number of days in Illinois with at least 2 inches of rain has increased by 40%.

2°F

Over the past century, nighttime temperatures in Illinois have risen about 2°F — three times the rate of daytime warming.

8 to 40 days

By mid-century, Illinois could experience 8-40 additional very hot days (95°F and above), depending on the level of greenhouse gas emissions.

Tackling Climate Change Locally

The Illinois Chapter is collaborating with partners on four pathways to tackle the issue of climate change in Illinois and beyond.

 

Mobilizing Climate Action in Rural Illinois

TNC is working across all 50 states to activate support for durable, bipartisan climate legislation at state and federal levels. In Illinois, we are actively engaging key federal congressional members, members of the Illinois state legislature, state agencies, and the Illinois Governor's office to open up dialogue on ambitious climate solutions and science-based climate policy. We are also taking steps to garner support for climate action with new constituencies, especially with our partners in rural Illinois.

 

Reducing Emissions with Natural Climate Solutions

Efforts to restore, protect, and sustainably manage natural areas is a critical component of limiting global warming to well below the 2°C threshold set by the Paris Agreement. In Illinois, the biggest, low-cost opportunities for employing natural climate solutions exist in the agricultural sector, using practices that some farmers are already employing to improve soil health, yields, and water quality. TNC sees a large opportunity to increase uptake of these agricultural best management practices through partnerships, capacity building and sensible climate change policy.

 

Promoting Low-impact Renewable Energy Deployment

Meeting climate change goals requires the rapid and large-scale deployment of renewable energy, which will invariably have impacts on the land. There are many steps we can take and many upsides to siting new renewable energy development in areas with the fewest adverse impacts to habitat, wildlife, and ecosystem services. TNC has developed useful tools and resources to guide decisions around low-impact siting, such as Site Wind Right. This interactive online map can help to inform turbine siting decisions across the Central United States. In the Illinois Chapter, we are working to increase the use of these tools and to promote the adoption of renewable energy siting guidance into relevant policies and plans.

 

Minimizing Flood Risk in Rural and Urban Communities

As local average temperatures and extreme weather events increase the frequency and magnitude of flooding and droughts, nature can be used as an important, cost-effective tool to enhance resiliency, helping human and natural systems adapt to the impacts of climate change. In rural areas, landscape approaches to land use planning can help to identify priority areas for floodplain restoration and reconnection—an excellent way to increase flood storage and decrease the flood risk to infrastructure and communities. In towns and cities, natural infrastructure in the form of bioswales, rain gardens, and tree planting, is a low-cost and effective approach for tackling issues like localized flooding, urban heat islands, and poor air quality. TNC would like to expand its work on climate adaptation in Illinois, to improve our reach in more communities across the state.
