Downloadable (with restrictions)! Benefit and cost uncertainty in provisioning of ecosystem services are investigated in the context of soil carbon sequestration. Multiple parcel-level carbon sequestration options are considered. Uncertainty has been a widely stated reason for not including soil carbon sequestration in the portfolio of greenhouse gases reduction measures. Biophysical simulation models are used to generate a distribution of resulting environmental benefits. An econometric model of conservation practice adoption is used to generate a distribution of costs. The results provide a magnitude of uncertainty discount for soil carbon offsets and the budget margin of safety, and may assist in formulating carbon sequestration policy.

Global warming as a result of rapid increase in atmospheric CO2 emission is significantly influencing worlds economy and human activities. Carbon sequestration in phytoliths is regarded as a highly stable carbon sink mechanism in terrestrial ecosystems to mitigate climate change. However, the response of plant phytolith-occluded carbon (PhytOC) to external silicon amendments remains unclear. In this study, we investigated the effects of basalt powder (BP) amendment on phytolith carbon sequestration in rice (Oryza sativa), a high-PhytOC accumulator. The results showed that the contents of phytolith and PhytOC in rice increased with BP amendment. The PhytOC production flux in different rice plant parts varied considerably (0.005-0.041 Mg CO2 ha-1 a-1 ), with the highest flux in the sheath. BP amendment can significantly enhance flux of phytolith carbon sequestration in croplands by 150 %. If the global rice cultivation of 1.55 9 108 ha had a similar flux of PhytOC production in this study, 0.61 9 107 to

Excess carbon dioxide in the atmosphere is a major contributor to global warming, and one of the methods proposed to reduce mankinds CO2 emissions is carbon sequestration - storing CO2 in deep within the earth and through farming and forestry practices. Scientists at MSU are on the forefront of both geologic and terrestrial carbon sequestration research. Geologic sequestration involves injecting liquefied or "supercritical" CO2 deep underground where it is stored in porous rock formations. The oil industry has been injecting relatively small amounts of CO2 underground for decades to enhance oil production, but now scientists are looking for ways to put billions of tons of CO2 safely underground. For decades, various industrial operations have injected and stored CO2 and other gases underground, and naturally occurring deposits of oil and gas trapped underground show scientists that CO2 can be safely and permanently stored beneath the ground. Now earth scientists at MSU are using new theories ...
A microbial mineral carbonation trial was conducted at the Woodsreef Asbestos Mine (NSW, Australia) to test cyanobacteria-accelerated Mg-carbonate mineral precipitation in mine tailings. The experiment aimed to produce a carbonate crust on the tailings pile surface using atmospheric carbon dioxide and magnesium from serpentine minerals (asbestiform chrysotile; Mg3Si2O5(OH)4) and brucite [Mg(OH)2]. The crust would serve two purposes: Sequestering carbon and stabilizing the hazardous tailings. Two plots (0.5 m3) on the tailings pile were treated with sulfuric acid prior to one plot being inoculated with a cyanobacteria-dominated consortium enriched from the mine pit lakes. After 11 weeks, mineral abundances in control and treated tailings were quantified by Rietveld refinement of powder X-ray diffraction data. Both treated plots possessed pyroaurite [Mg6Fe2(CO3)(OH)16·4H2O] at 2 cm depth, made visible by its orange-red color. The inoculated plot exhibited an increase in the hydromagnesite [Mg5(CO3)4(OH)2

Since fossil energy sources are very important throughout the world, carbon capture, utilization and storage (CCUS) plays a major role in order to achieve climate protection targets. Our solutions for carbon capture are: scrubbing CO2 from the flue gas of fossil-fired power plants (post-combustion carbon capture) as well as concepts and technologies for fuel gasifiers and power production linked with capturing carbon from the synthesis gas before its combustion (pre-combustion carbon capture). ...
Leakage from forest carbon sequestration-the amount of a programs direct carbon benefits undermined by carbon releases elsewhere-depends critically on demanders ability to substitute non-targeted timber for timber targeted by the program. Analytic, econometric, and sector-level optimization models are combined to estimate leakage from different forest carbon sequestration activities. Empirical estimates for the U.S. show leakage ranges from minimal (90 percent), depending on the activity and region.

Major disturbances have long-term influences on regional-scale carbon sequestration. Over a period of 30 years, the mountain beech forests were hit by a series of disturbance events that caused above-ground biomass to fall by 0.3 Mg C ha−1 year−1. If similar losses had occurred throughout the 2.9 million ha of Nothofagus forests in New Zealand (Wardle 1984), an estimated 870 Pg C year−1 would have moved from living biomass to detrital and atmospheric pools, equivalent to about 11% of New Zealands annual fossil fuel emissions (based on per capita consumption of 2 Mg C year−1). The simulation models suggest that, under realistic disturbance scenarios, above-ground carbon storage may fall by as much as 40% over a 40-year period and take equally long to recover (Fig. 8). Similar transformations are occurring in other regions. An outbreak of mountain pine beetle (Dendroctonus ponderosae) in British Columbia, Canada, is greater in extent and severity than any previously recorded, killing ...
Carbon Capture and Storage: Carbon Dioxide Pressure Dissipates in Underground Reservoirs, Study Shows. The debate surrounding carbon capture and storage intensifies as scientists from the Earth Sciences Division at the Lawrence Berkeley National Laboratory (Berkeley Lab) examine the capacity for storing carbon dioxide underground, in a study published today in the new journal Greenhouse Gases: Science & Technology.. The study debates some of the conclusions drawn in an earlier study by Ehlig-Economides and Economides1, countering their claims that carbon dioxide cannot feasibly be stored underground. These earlier findings, according to the Berkeley Lab researchers, only considered closed-system subsurface formations, with limited mechanisms for relieving the pressure.. Carbon capture and storage (CCS) is controversial in the eyes of the general public. Pressure build-up in the subsurface induced by the injection of carbon dioxide from industrial-scale projects is a key constraint for the amount ...

A recent article in the Guardian summarizes Regenerative Agriculture:. Regenerative agriculture comprises an array of techniques that rebuild soil and, in the process, sequester carbon. Typically, it uses cover crops and perennials so that bare soil is never exposed, and grazes animals in ways that mimic animals in nature. It also offers ecological benefits far beyond carbon storage: it stops soil erosion, remineralises soil, protects the purity of groundwater and reduces damaging pesticide and fertiliser runoff.. With these basic concepts of photosynthesis and Regenerative Agriculture in mind, what do we need to do?. (1) Regenerate croplands, eliminate GMOs, pesticides, monocultures, chemical fertilizers, and tillage. If we can mobilize the global grassroots to promote and adopt regenerative organic agricultural practices ("organic and beyond") on the Earths four billion acres of cultivated farmland, we can drastically reduce our use of fossil fuel inputs and slash greenhouse gas emissions; ...
Obj. 1A. A replicated six-year field experiment will be completed to evaluate the rate and quantity of carbon sequestrated by winter cover-crops of rye, hairy vetch, and a rye plus hairy vetch mixture, as compared to a traditional no-cover condition. These data will assess and develop agricultural practices for mitigating global warming. Obj. 1B. Agricultural use of biosolids could improve soil carbon sequestration and thereby reduce greenhouse-gas emissions. Replicated field research will be conducted on plots previously treated with different rates and types of biosolids, to determine if biosolids can increase soil carbon sequestration. Obj. 2A. Labeled nitrogen fertilizer will be used in a corn-wheat-soybean rotation to evaluate nitrogen use efficiencies of genetically modified and non-modified corn, to measure conservation of corn residual fertilizer by winter-wheat, and to estimate nitrogen fixation of double-crop soybeans. Improving nitrogen use efficiency will reduce nitrogen losses to ...
Overview:. In recent years, the U.S. Geological Survey has been conducting a national biologic carbon sequestration assessment in the conterminous U.S. The assessment is designed to meet the requirements of the Energy Independence and Security Act of 2007, which calls for coverage of all 50 states and all ecosystems (including forests, grasslands, wetlands, agricultural lands, and rivers, lakes, and estuaries). The assessment focuses on current and potential amounts of carbon stored in ecosystems, and effects of both natural and anthropogenic processes (such as fire, climate change, and land use change) on carbon sequestration. This project focuses on assessing current carbon stocks and potential change in carbon sequestration for the main Hawaiian Islands under future climate change scenarios. Existing carbon related data (land cover, fire, climate, soils, productivity, land use, wetland, etc.,) were collated and analyzed to develop an estimate of the current carbon stocks and fluxes under ...

ARPA-E sought information regarding the role of flexible carbon capture in terms of plant- and grid-level performance, economics and emissions. This workshop focused on the impact of a growing share of renewable generation on conventional power plants equipped with carbon capture and storage (CCS) systems. Future natural gas combined cycle (NGCC) plants, for example, will ramp their output, turn down to a low level, operate at a reduced capacity factor, and experience increasing fluctuations in locational marginal price signals.. Leading experts in carbon dioxide capture technologies and controls, plant- and grid-level modeling and techno-economic analysis, as well as materials scientists, chemists, and chemical, mechanical, and systems engineers, convened to explore how the design and operation of CCS systems could be modified to lower the cost of capturing CO2 given such constraints. Participants lent their expertise to help ARPA-E explore innovative technologies to determine relevant and ...

Low temperatures in the Arctic have through geological times caused a build-up of carbon (C) in the soil while carbon dioxide (CO2) has been removed from the atmosphere, because ecosystem respiration (ER) has been exceeded by the photosynthesis (GEP). Increasing air temperature, as occurring in current years, is likely to increase ER due to increased decomposition and increased substrate input e.g. due to permafrost thaw. If GEP is left unchanged and decomposition of old C from the soil is occurring this might result in an increase of the emission of CO2 to the atmosphere probably resulting in further warming. This PhD thesis addresses different aspects of climate change effects on C dynamics in the Arctic. The focus has been on i) changes in ER, age of the C sources, GEP and the net ecosystem exchange (NEE) in response to long- and short-term climate manipulations and ii) comparisons of CO2 fluxes and organic nutrient utilization between ecosystems occurring from different latitudes and ...
FAB-GGR is a new four-year, £2 million multi-institute consortium project that aims to better define the real world feasibility and consequences of large-scale afforestation and biomass energy with carbon capture and storage (BECCS) approaches to greenhouse gas removal (GGR). These two greenhouse gas removal approaches have been chosen because they: have a common basis in growing biomass on available land; and play the largest roles of any GGR approaches in future low emission scenarios that keep global mean temperature increase to below 1.5 °C and 2 °C.
The Global CCS Institute is an international member-led organisation whose mission is to accelerate the deployment of CCS to tackle climate change and provide energy security.
We are mapping the production of carbon cycle science, from the needs of those who make decisions to the scientists and agencies that supply scientific information and then back to the decision makers who might use the information. By comparing the supply and demand sectors of carbon cycle science, we will assess where linkages between the sectors are strong and where missed opportunities for linkage exist.
SARAIVA, Maria das Graças Gomes et al. Urban expansion and spatial distribution of malaria in the municipality of Manaus, State of Amazonas. Rev. Soc. Bras. Med. Trop. [online]. 2009, vol.42, n.5, pp.515-522. ISSN 0037-8682. http://dx.doi.org/10.1590/S0037-86822009000500008.. In the municipality of Manaus, intensification of the migratory process, along with precarious epidemiological and entomological surveillance, resulted in reintroduction of malaria transmission on the urban perimeter (in the eastern zone), in July 1988, after 13 years without any records of autochthonous disease. This study reports on the epidemiological situation relating to malaria and to the areas that were subjected to human actions (deforestation, human settlement, fish-rearing activity, etc) in Manaus, between 1986 and 2005. In this municipality, the population increase from 1986 to 2005 was 105.2%. This resulted from occupation of space, in the form of invasions and housing projects. From 2003, the increase in ...
Harken! Good news (maybe) "encouraging news" is a better description, as Negative Emissions Technology ("NET") starts coming into focus. Conceptually, carbon removal or direct air capture removes CO2 from the atmosphere, which would be great for suppressing climate change.. In that regard, Elizabeth Kolbert recently interviewed (Yale Environment 360) Stephen Pacala (Princeton professor) chairman of the US scientific panel studying carbon removal under the auspices of the National Academies. Which means the project has top-notch clearances, in fact, blue chip.. Of course, the big question about direct carbon capture is whether it can fix a very big problem created by humans burning fossil fuels like crazed Madhatters portending an ecological disaster-in-waiting because of excessive levels of CO2 in the atmosphere, possibly leading to human extinction way ahead of schedule, too early, or looked at another way, extinction occurring well ahead of scientists models. But really, honestly and truly ...
The Kyoto Protocols Clean Development Mechanism (CDM) was created to aid clean development by allowing wealthy nations to invest in the developing world as a way to cut their greenhouse gas emissions and claim credits against their own emission reduction targets.It is intended to help the developing world leapfrog dirty development and avoid dependence on coal and other fossil fuels. According to the rules governing the CDM, projects must promote fair geographic distribution and should lead to the transfer of environmentally safe and sound technology. CDM projects must be cost effective and also contribute to sustainable development.Carbon Capture and Storage (CCS), the process of capturing, transporting and storing CO2 from coal fired power stations, does not meet any of these criteria, yet some governments continue to push for its inclusion.
Before genomics techniques, the dark ocean was a black box, because microorganisms from this environment refuse to grow in research laboratories," said Ramunas Stepanauskas, a senior research scientist at Bigelow Laboratory and director of the Single Cell Genomics Center. "Now, using contemporary tools that were developed by our group, we can open this black box and understand who is living there, what they are doing, and how they are doing it.". The research behind this Science paper began with an effort to identify new groups of microscopic organisms in the mesopelagic zone. According to Pachiadaki, the previously accepted explanation for carbon capture in the dark ocean did not seem correct under close inspection. Archaea, a much more abundant group of microorganisms in the dark ocean, had been credited with doing most of the work, but the math just didnt add up. The team set out to discover the unidentified organisms that were the true champions of carbon dioxide capture in the vast dark ...

Calcite is a mineral made of calcium, carbon, and oxygen that is all the more generally known as the sedimentary forerunner to limestone and marble. In the sea, calcite is a residue framed from the shells of life forms, similar to tiny fish, that have kicked the bucket and sunk to the ocean bottom. Calcium carbonate is likewise the material that makes up coral reefs - the exoskeleton of the coral polyp.. As air carbon dioxide levels have ascended past 400 sections for each million - a typical benchmark for atmosphere researchers affirming that the impacts of the ozone harming substance in the climate will be felt for eras to come - the surface seas have assimilated increasingly of that carbon dioxide. This is a piece of a characteristic buffering process - the seas go about as a noteworthy repository of carbon dioxide. Right now, they hold approximately 50 fold the amount of the ozone depleting substance as the climate.. In any case, there is a moment, slower, buffering process that expels ...
