Carbon cycle conundrums [PDF]

Proceedings of the National Academy of Sciences, 2007
What will control future rates of climate change? The carbon cycle is the largest contributor to anthropogenic climate change, yet despite decades of research (1), significant mysteries about its behavior remain. Global analyses show that the Earth system absorbs approximately half of anthropogenic fossil fuel emissions.

Research on the Development of Carbon-Neutral Circular Economy based on an Environmental Protection Strategy [PDF]

E3S Web of Conferences, 2023
The carbon circular economy is a new idea to achieve a circular economy that is green and low-carbon and respond to global climate change. It is a more sustainable, carbon-neutral, and zero-emission energy system solution. China can create a cutting-edge

Cooling water use in thermoelectric power generation and its associated challenges for addressing water-energy nexus

Water-Energy Nexus, 2018
Thermoelectric power plants traditionally have required huge volumes of water to condense steam from the turbine exhaust. The complex interdependency between water and energy poses new challenges for policy makers to achieve a safe, secure and ...

Mesoscale eddies heterogeneously modulate CO₂ fluxes in eddy-rich regions of the Southern Ocean [PDF]

Biogeosciences
Mesoscale eddies are known to influence the Southern Ocean biogeochemistry. However, the distinct contributions of cyclonic and anticyclonic eddies to air–sea CO2 fluxes, as well as their longer-term effects remain poorly studied. We present results from

Australian climate-carbon cycle feedback reduced by soil black carbon [PDF]

, 2008
Annual emissions of carbon dioxide from soil organic carbon are an order of magnitude greater than all anthropogenic carbon dioxide emissions taken together1.

The global terrestrial carbon cycle

Water, Air, & Soil Pollution, 1993
There is great uncertainty with regard to the future role of the terrestrial biosphere in the global carbon cycle. The uncertainty arises from both an inadequate understanding of current pools and fluxes as well as the potential effects of rising atmospheric concentrations of CO2 on natural ecosystems.

Spatiotemporal Response and Driving Factors of Carbon Stocks to Land Use Change in Southwest China Karst Region

Ecosystem Health and Sustainability
Karst landscapes serve as vital carbon reservoirs, yet the long-term dynamics of their multiple carbon pools and the underlying driving mechanisms remain insufficiently understood.

National forest carbon harvesting and allocation dataset for the period 2003 to 2018 [PDF]

Earth System Science Data
Forest harvesting is one of the anthropogenic activities that most significantly affect the carbon budget of forests. However, the absence of explicit spatial information on harvested carbon poses a huge challenge in assessing forest-harvesting impacts ...

Integrated modeling of blue and green water evolution in a headwater region of Chaohu Lake: Impacts of climate and surface environmental factors

Ecological Indicators
Understanding the dynamic changes of blue water (BW, surface and groundwater) and green water (GW, soil-stored rainfall used by plants via evapotranspiration) is essential for assessing water resource sustainability.

Integrated geochemical and geophysical assessment for monitoring soil stabilization with waste oyster shells

Scientific Reports
We assessed the field-scale stabilization efficiency of lead (Pb) and copper (Cu) in contaminated soils using powdered (WOS-P) and granular (WOS-G) waste oyster shell (WOS) amendments.
