(Phys.org) —Increasing levels of carbon dioxide (CO2) in the atmosphere are causing oceans to become more acidic. This situation poses a threat to marine organisms with shells made of calcium carbonate, because acid will ...
Plenty has been written about concerns over elevated levels of carbon dioxide in the earth's atmosphere, but a Kansas State University researcher has found an upside to the higher CO2 levels. And it's been particularly relevant ...
