It’s a first step toward a hoped-for system that would track carbon dioxide and pH in all five Great Lakes over multiple years, said project co-leader Reagan Errera of the National Oceanic and Atmospheric Administration (NOAA). Photo: APOceans are becoming more acidic as they absorb carbon dioxide that human activity pumps into the atmosphere — the primary cause of climate change. Researchers say Great Lakes also could approach acidity around the same rate as in oceans by 2100. One measures carbon dioxide pressure in the water column and the other pH. Increasing water acidity in lab tanks to projected 2100 levels more than tripled their mortality rates, according to a report last year.
