Summary
The arctic landmass is covered by numerous shallow ponds, lakes, and streams (see the photo). On page 925 of this issue, Cory et al. (1) show that sunlight drives the production of substantial amounts of carbon dioxide in these waters through photochemical oxidation of organic matter. The results have important implications for the carbon cycle in the Arctic and how it responds to, and possibly even magnifies, climate change.
