Amelia Snow Dr Oscar Schofield and Dr Grace Saba The CO 2 Problem Since 1800s 40 increase Preindustrial 280 ppm Current 385ppm 05 increase per year Ocean absorbs 13 CO 2 in atmosphere. Rockefeller Jr Memorial PKWY Big Hole NB Cowpens NB Fort Donelson NB Fort Necessity NB Moores Creek NB Petersburg NB Stones River NB Tupelo NB Wilsons Creek NB Kennesaw Mountain NBP Richmond NBP Brices Cross Roads NBS Chickamauga and Chattanooga NMP For tens of millions of years, Earth's oceans have maintained a relatively stable acidity level. It's within this steady environment that the rich and varied web of life in today's seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences.. Key understanding. Due to the use of unsustainable energy, ocean acidification is a rising problem for marine ecosystems. The high levels of pH (acidity) in the water alters the natural chemical bonding process in regards to the building of shells and exoskeletons of marine wildlife. The rising level of .
