In peatland soil, a warmer climate and elevated carbon dioxide rapidly alter soil organic matter Soils in northern freshwater wetlands, called peatlands, are cold, water-saturated, and acidic. These conditions slow microbes' decomposition of organic matter into greenhouse gases. This process stores carbon in the soil. Researchers use the Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment to warm air and soil in a northern Minnesota bog to simulate the effects of climate change on the carbon cycle. https://phys.org/news/2024-03-peatland-soil-warmer-climate-elevated.html Environment Wed, 06 Mar 2024 16:32:29 EST news628965147 Deep sea and sediments bring iron to Antarctic waters, finds researcher Deep sea and sediments bring iron to Antarctic waters.
