Biogenic emissions: high
WebOct 7, 2024 · Biogenic carbons refer to all those which are stored in, sequestered by and emitted through organic matter. The most common biogenic feedstocks include trees, plants and soil, which absorb carbon as a natural part of their life cycle. This process occurs during photosynthesis, when organic flora removes carbon from the atmosphere and … WebNov 20, 2011 · During high temperatures, coniferous forests emit more terpenes to cool off and combat heat stress. Coniferous trees constantly emit these gases, but higher temperatures spur more emissions. Abbatt said, “Often the northern and boreal forests, which contain more of the coniferous trees, tend to be colder than forests in the tropics, …
