Scientists say melting glaciers are increasing ocean organic carbon levels, according to a Live Science article. Organic carbon in the glaciers typically comes from microbes living inside the glaciers or contaminants.
A team of Florida State University researchers concluded that carbon levels will increase 50 percent by 2050 if glacial melting continues at the same rate. The research team plans to pursue further research to verify if the projected carbon increase will be a big issue for marine ecosystems.
Researchers are concerned that microorganisms that feed on carbon may adapt to the carbon surplus. Once the carbon sources are depleted, their ecosystems could be compromised.
