Acid test: Threat to oceans may also harm Great Lakes
The increased carbon dioxide changing the water chemistry and ecology of oceans may also be affecting freshwater and the organisms that live in it.
It’s called ocean acidification. But some researchers suspect it will impact the Great Lakes.
“Based on our preliminary modeling and understanding of carbon cycles, we think similar acidification trends
