Study finds glacial rivers absorb 40 times more carbon than rainforests

A study published in the Proceedings of the National Academy of Sciences shows that glacial rivers in northern Canada absorb carbon dioxide from the atmosphere faster than the Amazon rainforest, according to foreign media reports. The study analyzed melting glacial water samples taken from Ellesmere Island in Canada and found that the concentration of carbon dioxide in glacial rivers was much lower than in the atmosphere, and that rivers were absorbing carbon dioxide.

Glaciers have huge surface deposits, which, because they are mixed with water and then with the atmosphere, can have many potential chemical weathering reactions, some of which consume carbon dioxide.

The researchers found the effect of chemical weathering to remove carbon dioxide, which extends 26 miles (42 kilometers) from the source of the river. This means that during the high melting period, glacial rivers will absorb 40 times as much carbon as the Amazon rainforest.

But the researchers also point out that glaciers have limited resources and absorb far less carbon dioxide than the Amazon rainforest, and scientists are calling attention to climate change, and That Canadian glaciers are melting at a rapid rate.
