WebOct 31, 2024 · Emissions of greenhouse gases (GHG) such as CO 2 and N 2 O from soils are affected by many factors such as climate change, soil carbon content, and soil nutrient conditions. However, the response patterns and controls of soil CO 2 and N 2 O fluxes to global warming and nitrogen (N) fertilization are still not clear in subalpine forests.
WebApr 3, 2013 · The History of the Keeling Curve. Carbon dioxide is a greenhouse gas produced by natural processes and everyday human activities, especially the burning of fossil fuels. The Keeling Curve is a measurement of the concentration of carbon dioxide in the atmosphere made atop Hawaii’s Mauna Loa since 1958. It is the longest-running … WebGreenhouse gas levels are so high primarily because humans have released them into the air by burning fossil fuels.
