In comparison to a 'flipped'" glacial Pacific overturning structure, we find the most 14 C-depleted water in glacial Pacific bottom depths rather than the mid-depths as they are today, which can be best described by a sloweddown in glacial deep-sea overturning process rather than the mid-depths.
Due to the high amount of carbon that will need to be stored, it is expected that the bulk of this storage would be stored in the subsurface by geologic storage. Subsurface carbon storage must be minimized to a minimum in order to be efficient, and subsurface carbon storage must be limited to a minimum. Water-dissolved CO 2 tends to be denser than CO2-free water, and its injection initiates immediate solubility storage in the subsurface. Generally speaking, the injection of CO 2 charged water results in the safe storage of injected CO 2 as long as the water to CO 2 ratio is no less than 24 to 1. The salinity of the original formation water much exceeds that of the CO 2 -charged injection water, which is the equivity of the CO 2 -charged injection water.
Biophysical factors also amplify carbon losses in the Congo, but they do not lead to significant additional carbon losses in tropical Asia due to the country's high amounts of annual mean precipitation. Tropical forests can be undervalued in carbon accounting methods that neglect surface biophysical feedback, and they note that the positive carbon-climate feedback from deforestation-driven climate change is higher than that originating from fossil fuel emissions, which can be dependant on fossil fuel emissions. These results show that tropical forests may be undervalued in carbon accounting tools that ignore surface biophysical measurements, and that positive climate feedback from deforestation-driven climate change is more significant than climate feedback generated by fossil fuel emissions.
Trees on grazing lands provide and can enhance several ecosystem services, including carbon sequestration, cultural, and regulating that include carbon sequestration. We examined the above- and belowground carbon stocks in six different land-uses of Mexico's livestock-dominated landscapes. We measured tree biomass and soil organic carbon stocks in fodder banks, live fences, pasturelands with dispersed trees, secondary forests, and primary forests from three different geographical regions and compared them to conventional open pasturelands respectively. We also calculated tree diversity indices for each land-use and their similarity with native primary forests. The aboveground woody biomass stocks varied significantly between land-uses and followed the change from less accessible traditional open pasturelands to silvopastoral pathways and ecologically complex primary forests, with less diverse traditional open pasturelands to more mature primary forests. Depending on the study area, SOC stocks had a variable response to the land-use gradient. Compared to open pasturelands, Silvopastoral plants and forest remnants stored 27-163% more carbon than open pasturelands.
Based on field results and mineralogical and geochemical results, an investigation of the possible shale gas play and geological carbon dioxide storage from the Triassic Huai Hin Lat Formation in Thailand was carried out. This research was mainly focused on mudstone samples in several areas of the Huai Hin Lat Formation. The samples' total organic carbon and extractable organic matter of the samples showed poor to excellent generation capability for hydrocarbon source rock with type III kerogen. The Huai Hin Lat Formation occurs in anoxic to suboxic conditions in an aquatic depositional environment, according to the depositional environment.
Oxygen in the ocean has essential ecological and climatic properties, and it can be a good indicator of deep-ocean ventilation and carbon storage. Authorigenic uranium in deep-sea sediments is a versatile redox tracer that can give a clue to bottom water oxygen. During the Holocene and the LGM, we used published and new U- and Th-series isotope measurements from North Atlantic sediments to determine the mass accumulation rate of authigenic uranium during the Holocene and the LGM. The LGM in the deep North Atlantic contained higher aU burial, reflecting lower-than-Holocene oxygen levels and thus higher respired carbon storage. We found that higher aU burial revealed lower-than-Holocene oxygen levels and relatedly increased respiration carbon storage. The eastern basin was noticeably less hot than the western basin, and it was less humid than the western basin. The difference in residence time in the two basins of deep waters originating from the subpolar North Atlantic's subtropic North Atlantic is an alternative explanation.
