Glaciers and ice sheets contain about 70 percent of the Earth's fresh water, and ongoing melting contributes significantly to rising sea levels. But glaciers also store organic carbon derived from primary production and the deposition of materials such as soot and other byproducts of fossil fuel combustion.

An international team of researchers, led by Eran Hood of the University of Southeast Alaska, studied the ice sheets in mountain glaciers globally and the Greenland and Antarctic ice sheets to measure the total amount of carbon. organic stored in the global ice bin. And it is a lot. According to his estimate, the carbon emission from the melting of glaciers will increase by 50% in the next 35 years.

"This research shows that glaciers represent a significant store of organic carbon," says Eran Hood, lead author of the study. "As a result, the loss of glacier mass around the world together with the release of carbon will affect marine ecosystems at high latitudes, especially those around the large ice sheets." "This is the first attempt to calculate how much carbon is in glaciers and how much will be released when they melt," explains Robert Spencer, a professor at Florida State University, who has also participated in the research. "It could change the entire food chain. We don't know how different ecological systems will react to a new influx of carbon."

In this sense, the researchers continue with this line of research to try to determine exactly what the impact will be on water masses when carbon is released: "We know that we are losing glaciers, but what does that mean for marine life, for fishing, for example? "
