Don't bother with the EPA's latest assessment to get a true picture of impact climate change on the Great Lakes

Caitlin Looby reports:
As the Great Lakes face mounting pressures, a new binational assessment offers a mixed report card on the health of the world's largest surface freshwater system. But whether it gives a complete picture is another story. 
The U.S. EPA and Canada released the 2025 State of the Great Lakes on Jan. 20, outlining successes and ongoing threats to the Great Lakes. The report, which has been released every three years, scores each lake based on indicators established in the Great Lakes Water Quality agreement, a commitment between the two countries to protect and restore the Great Lakes. 
In the new report, each of the five Great Lakes gets a score − good, fair or poor − as well as an indicator showing if the lake is improving, deteriorating, unchanging or shows no trend. These scores are based on nine factors that assess ecosystem health: drinking water, beaches, fish consumption, toxic chemicals, habitat and species, invasive species, nutrients and algae, groundwater, and watershed impacts. 
But there were also key missing pieces, one of which was climate change.
