Throughout its long history the Earth has undergone warm periods with high atmospheric concentrations of greenhouse gases (GHG), and has responded with different buffering mechanisms whereby atmospheric C has been transferred to other geochemical compartments. Strategies for the mitigation and adaptation to the current climatic forcing may thus be generated by the acceleration of such natural mechanisms, especially those involved in short cycles, mainly in the biosphere and the pedosphere… 
Terrestrial Biosphere as a Source and Sink of Atmospheric Carbon Dioxide
The terrestrial biosphere has lost a considerable amount of its antecedent carbon (C) pool because of anthropogenic activities since the dawn of settled agriculture about 12–14 millennia ago.
Factors affecting CO2 efflux rates and the stability of soil organic carbon storage in volcanic soils of the Canary Islands
Because volcanic soils store large amounts of soil organic carbon (SOC), they play a far more important role in the carbon (C) cycle than their limited global coverage suggests. We analysed the C
Carbon sequestration in soil
Soil carbon (C) sequestration implies transferring of atmospheric CO2 into soil of a land unit through its plants. Co-benefits of soil C sequestration include: advancing food and nutritional

Breeding crops with desirable below-ground C sequestration traits, and exploiting attendant agronomic practices optimised for individual species in their relevant environments, are important goals.
Managing soil carbon stocks to enhance the resilience of urban ecosystems
Abstract Land-use and land-cover change (LULCC) by urbanization will likely replace agricultural expansion as the dominant source of transformation of the terrestrial biosphere. Properly managed
Biochar application to soil for climate change mitigation by soil organic carbon sequestration
Pyrogenic carbon (C) is produced by incomplete combustion of fuels including organic matter (OM). Certain ranges in the combustion continuum are termed ‘black carbon' (BC). Because of its assumed
Carbon Sequestration in Cropland Soils
Humans began to cultivate land thousands of years ago, for growing crops after clearing the previous vegetation cover and plowing the soil. The soil disturbance altered, in particular, soil C
Cropland Soil Carbon Dynamics
Humans began thousands of years ago to cultivate land for growing crops after clearing the previous vegetation cover and plowing the soil. The soil disturbance altered soil carbon (C) dynamics which
Soil Nutrient and Greenhouse Gas Cycles in Managed Mixed Deciduous Ontario Forests: The Role of Elevated Atmospheric Nitrogen Deposition and Nutrient and Biochar Amendments
Canada’s temperate forests are experiencing an environmental disturbance in the form of atmospheric nitrogen deposition arising from fossil fuel burning and agricultural practices. Nitrogen, a major

The increase in atmospheric concentration of CO2 by 31% since 1750 from fossil fuel combustion and land use change necessitates identification of strategies for mitigating the threat of the attendant
Bio-char Sequestration in Terrestrial Ecosystems – A Review
The application of bio-char (charcoal or biomass-derived black carbon (C)) to soil is proposed as a novel approach to establish a significant, long-term, sink for atmospheric carbon dioxide in
Continental Erosion and Co2 Uptake. Inferences from the Himalayan System
Continental erosion via silicate weathering or organic carbon erosion/burial is considered has a first order control on long term changes in the level of CO2 in the atmosphere and thereby on climatic
The global carbon cycle: a test of our knowledge of earth as a system.
It is concluded that although natural processes can potentially slow the rate of increase in atmospheric CO2, there is no natural "savior" waiting to assimilate all the anthropogenically produced CO2 in the coming century.
Erosion-related soil carbon fluxes in a pastoral steepland catchment, New Zealand
Abstract New Zealand is currently identifying and quantifying its carbon sources and sinks to develop a national carbon budget. This will enable it to set policy and targets to reduce greenhouse gas
Coupled modeling of global carbon cycle and climate in the Neoproterozoic: links between Rodinia breakup and major glaciations
A coupled climate–geochemical model of new generation (GEOCLIM) is used to investigate the possible causes of the initiation of snowball glaciations during Neoproterozoic times. This model allows the

The global carbon budget is, of course, balanced. The conservation of carbon and the first law of thermodynamics are intact. “Balancing the carbon budget” refers to the state of the science in

Revision of the GEOCARB model (Berner, 1991, 1994) for paleolevels of atmospheric CO2, has been made with emphasis on factors affecting CO2 uptake by continental weathering. This includes: (1) new
Stabilization of organic matter in temperate soils: mechanisms and their relevance under different soil conditions – a review
Summary Mechanisms for C stabilization in soils have received much interest recently due to their relevance in the global C cycle. Here we review the mechanisms that are currently, but often
