Sentences with phrase «land carbon processes»

Figure 7.14 shows how uncertainties in the sensitivities of ocean and land carbon processes contribute to uncertainties in the fraction of emissions that remain in the atmosphere.

Not exact matches

The simulations also suggest that the removal of excess carbon dioxide from the atmosphere by natural processes on land and in the ocean will become less efficient as the planet warms.

Like plants on land, phytoplankton produce energy by photosynthesis, pulling carbon dioxide from the atmosphere to fuel the process.

But when the land is converted for agriculture, the plants are cut down, burned, or processed, and the stored carbon is eventually released back into the atmosphere as greenhouse gases.

«The simple relationship between the temperature and the global land carbon sink should be treated with caution, and not be used to infer ecological processes and long - term predictions» adds Dr. Reichstein, head of the Department.

Also, rainforests affect climate through other processes in addition to acting as carbon sinks and stores — they promote evaporation, which keeps the land cooler and helps recycle rainfall.»

series of processes in which carbon (C) atoms circulate through Earth's land, ocean, atmosphere, and interior.

«If the total sink is about 0.3 Pg of carbon per year, and the CO2 / climate sink is about 0.1 Pg of carbon per year, other processes such as regrowth on abandoned agricultural and harvested forest lands must cause a sink of about 0.2 Pg of carbon per year.»

Since the industrial revolution, we have been burning fossil fuels and clearing and burning forested land at an unprecedented rate, and these processes convert organic carbon into CO2.»

Wherever one of the land use changes decreased soil C, the reverse process usually increased soil carbon and vice versa.

-- Enhanced weathering processes on land and in the ocean to accelerate natural removal of carbon dioxide from the atmosphere have only been carried out on a limited scale with intermediate technological readiness.

He has done research and consultancy on urban energy modeling, urban greenhouse gas (GHG) inventory, integrated land - use and transport policies, real estate and housing markets, Urban green growth, carbon finance and cities, city networks and post-2012 negotiation process.

A further step would be to develop a product - based approach that accounts for typical carbon sequestration during the growing phase, carbon emissions from processing, and implicit emissions from land use changes as well as combustion emissions for each biofuel and biomass type.

Tax approximate CO2 emissions from final combustion of biofuels and biomass based strictly on product type without attempting to account for carbon sequestered during growth cycles or emitted during harvesting, distillation or other chemical processing or land - use impacts.

Four additional carbon offset methodologies are currently in ACR's approval process for publication in 2013 including California and Mid-South modules for Emission Reductions in Rice Production, a modular approach to Grazing Land and Livestock Management in beef and dairy production, a methodology for Avoided Conversion of Grasslands and Shrublands to commodity crop production, and a methodology for quantifying emissions reductions from Carbon Capture and Storage in Oil and Gas Reservoirs.

Modifying land use, will more dramatically reduce CO2 concentrations than any warm and fuzzy carbon Ponzie scheme and might actually solve other issues in the process.

The flow of dissolved organic carbon (DOC) from land to sea typically accounts for a small fraction of an ecosystem's carbon budget compared with processes like photosynthesis and respiration.

The myriad of processes that transform energy, that result in the motion of mass in the atmosphere, in oceans, and on land, processes that drive the global water, carbon, and other biogeochemical cycles, all have in common that they are irreversible in their nature.»

However, today's carbon cycle models, especially the land models, vary greatly in the processes and level of detail they include, and so averaging may not be appropriate.

Forward, process - based models are used to study both carbon and land - surface climate.

The following sections explain the controls on these fluxes, with special reference to processes by which anthropogenic changes may influence the overall carbon balance of the land and oceans on time - scales from years to centuries.

ESM 202 - Environmental Biogeochemistry [4 units] Melack & Holden Biogeochemical processes as applied to the Earth's atmosphere, oceans, land, and inland waters, and applications to environmental issues such as eutrophication, toxic pollution, carbon sequestration, and acidification.

Carbon dioxide (CO2)- A naturally occurring gas, also a by - product of burning fossil fuels from fossil carbon deposits, such as oil, gas and coal, of burning biomass and of land use changes and other industrial processes.

The company is proposing to build the gas processing and carbon sequestration facility within an 872 - acre site that includes state, private and federal lands.

This implies that the observed CO2 growth in the atmosphere does not only depend on anthropogenic emissions, but also on natural processes that have the potential to capture or release CO2 into or from the ocean and land reservoirs of carbon.

The term «negative emissions» designates CO2 that is removed from the atmosphere, and can refer to either techno - industrial processes (e.g., Biomass Energy with Carbon Capture and Sequestration, or BECCS) or changes in land - use practices that yield substantial enhancement of carbon sinks (e.g. afforestation and low - carbon agro-ecological techniques).

This new concept of anthropogenic impacts on seawater pH formulated here accommodates the broad range of mechanisms involved in the anthropogenic forcing of pH in coastal ecosystems, including changes in land use, nutrient inputs, ecosystem structure and net metabolism, and emissions of gases to the atmosphere affecting the carbon system and associated pH. The new paradigm is applicable across marine systems, from open - ocean and ocean - dominated coastal systems, where OA by anthropogenic CO2 is the dominant mechanism of anthropogenic impacts on marine pH, to coastal ecosystems where a range of natural and anthropogenic processes may operate to affect pH.

This paper was released as part of a process to give further consideration to the complexities of carbon farming on Aboriginal and Torres Strait Islander land.
