An Introduction to Sediment Records of Biomass Burningcts atmospheric chemistry, the carbon cycle, and climate and may have done so for millions of years. Literature values place carbon sequestration during biomass burning in excess of 20% of the total anthropogenic C releases to the atmosphere, which, failing oxidative losses, would tie up the globe’s作者: insecticide 時間: 2025-3-22 00:49 作者: cardiovascular 時間: 2025-3-22 04:50 作者: 拱形面包 時間: 2025-3-22 09:11

Biomass Burning Emissions and the Atmosphereon fires. Crutzen and Andreae (1990) have estimated that global emissions of pyrogenic smoke particles (50–150 Tg yr.) may currently exceed global sulfate aerosol produced from fossil fuel burning. These pyrogenic particulates are largely composed of carbonaceous materials (Crutzen and Andreae 1990,作者: 影響深遠 時間: 2025-3-23 09:49 作者: nitric-oxide 時間: 2025-3-23 15:21

Reconstructing Environmental Impacts of Fire from the Holocene Sedimentary Record I outline quantitative approaches to the reconstruction of the impacts that fires may have had on environmental variables during the Holocene.

The Sedimentary Record of Fire in Montane Meadows, Sierra Nevada, California, USA: a Preliminary Assegional fire periods and their relationship to climate during the Holocene. With the exception of the period of 8700 to 9200 yr BP, charcoal is less frequently encountered in early Holocene sediments than it is in sediments deposited after 4500 yr BP. We hypothesize a climatic control. Empirical and作者: 占卜者 時間: 2025-3-24 07:16

Proposed Bio-geological and Chemical Based Terminology for Fire-altered Plant Mattered. It is recommended that certain terms that have precise meanings in other fields should be either used with caution or discarded. Several existing terms should be disregarded, because they pre-suppose a mode of formation or structure for which the evidence is poor or incorrect.作者: 使饑餓 時間: 2025-3-24 16:24
Reconstruction Of Paleo-Fire Through Climate And Eco-System Modelsecosystem, and second, requires that we assume that current models of fire behavior will apply. These key assumptions can be restated as hypotheses: can current modeling capability reproduce paleo-fire? and, can climate models, coupled with ecosystem models and fire models, replicate the spatial patterns of fire emissions?作者: Concerto 時間: 2025-3-24 21:34

The Sedimentary Record of Fire in Montane Meadows, Sierra Nevada, California, USA: a Preliminary Ass modeled data suggest that the early Holocene was xerothermic in the Sierra Nevada. Pollen evidence suggests forests were more open than today, thus producing less tree biomass for fuel. Intensification of El Ni?o during the middle Holocene may have been important in changing the character of the Sierran forests as well.作者: 控制 時間: 2025-3-25 15:08 作者: Palate 時間: 2025-3-25 19:24 作者: Geyser 時間: 2025-3-25 22:01
