It probably comes as no surprise to those living in the Great Lakes region to hear that this spring was one of the coldest on record. Since 1948, there have been only four years with lower spring temperatures. And these unusually cold temperatures—and the snow that came with them—had significant impacts on Great Lakes ecosystems, communities, and economies. 
 
These impacts are the focus of the latest edition of the Great Lakes Quarterly Climate Impacts and Outlook report. Released in June, the report details how the long winter helped lake levels rebound from record lows, forced cities to invest more in winter operational expenses and infrastructure maintenance, and has left some farmers concerned about this year’s crop. It also provides a look at expected temperatures and precipitation levels for the coming months. 
 
The Great Lakes Quarterly Climate Impacts and Outlooks is developed by NOAA and Environment Canada. Past editions, as well as reports for other regions, are available at the U.S. Drought Portal.

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)
