Multicentury Changes to the Global Climate and Carbon Cycle: Results from a Coupled Climate and Carbon Cycle Model
A coupled climate and carbon (CO2) cycle model is used to investigate the global climate and carbon cycle changes out to the year 2300 that would occur if CO2 emissions from all the currently estimated fossil fuel resources were released to the atmosphere. By the year 2300, the global climate warms by about 8 K and atmospheric CO2 reaches 1423 ppmv. The warming is higher than anticipated becaus...
متن کاملSoil carbon sequestration impacts on global climate change and food security.
The carbon sink capacity of the world's agricultural and degraded soils is 50 to 66% of the historic carbon loss of 42 to 78 gigatons of carbon. The rate of soil organic carbon sequestration with adoption of recommended technologies depends on soil texture and structure, rainfall, temperature, farming system, and soil management. Strategies to increase the soil carbon pool include soil restorat...

Understanding the Impacts of Large-Scale Climate Variability on the Global Carbon Cycle
Recap of project goals The principle goal of the research project is to bring together scientists with seemingly disparate expertise to systematically develop and test hypotheses regarding the impact of large scale climate variability on the carbon cycle. The research is largely focused on the dominant patterns of hemispheric scale variability, the so-called Northern and Southern Hemisphere ann...
متن کاملImplications of a large global root biomass for carbon sink estimates and for soil carbon dynamics.
Recent evidence suggests that significantly more plant carbon (C) is stored below ground than existing estimates indicate. This study explores the implications for biome C pool sizes and global C fluxes. It predicts a root C pool of at least 268 Pg, 68% larger than previously thought. Although still a low-precision estimate (owing to the uncertainties of biome-scale measurements), a global root...
