Higher temperatures, extreme rainstorms, loss of wildlife, and a drop in Lake Michigan water levels. This is what the Midwest can expect in the coming decades according to the latest review of climate change trends.
 
Released on Tuesday, the 2014 National Climate Assessment provides an in-depth look at the expected impacts of climate change across the country. The report also investigates how businesses, agriculture, infrastructure, natural resources, and public health will be affected if current trends continue.
 
Midwesterners have likely noticed a few of the projected changes already. Summers are longer and warmer, winters are wetter, and flooding is increasing. But some of the long-term impacts might not be as apparent. For example, higher water temperatures could drive out fish species and make it easier for non-native species to invade new habitats. Stronger rainstorms, especially in cities, will also mean more runoff that pollutes waterways and erodes shorelines and river banks.

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.Watch the 3-part video series at the link in bio.(Photo credit: Liz Spitzer, Illinois State Geological Survey, Coastal Research Group)
