  • ARCTIC tundra has been a net sink for carbon dioxide during historic and recent geological times1–4, and large amounts of carbon are stored in the soils of northern ecosystems. Many regions of the Arctic are warmer now than they have been in the past5–10, and this warming may cause the soil to change from a carbon dioxide sink to a source by lowering the water table11–12, thereby accelerating the rate of soil decomposition (CO2 source)3,13–15 so that this dominates over photosynthesis (CO2 sink… CONTINUE READING
