Probabilistic forecast for twenty-first-century climate based on uncertainties in emissions (without policy) and climate parameters
(American Meteorological Society, 2009-10-01)
The Massachusetts Institute of Technology (MIT) Integrated Global System Model is used to make probabilistic projections of climate change from 1861 to 2100. Since the model’s first projections were published in 2003, ...
Effects of tropospheric ozone pollution on net primary productivity and carbon storage in terrestrial ecosystems of China
(American Geophysical Union, 2007-11-17)
We investigated the potential effects of elevated ozone (O3) along with climate variability, increasing CO2, and land use change on net primary productivity (NPP) and carbon storage in China's terrestrial ecosystems for ...

Pattern and variation of C:N:P ratios in China’s soils : a synthesis of observational data
Inspired by previous studies that have indicated consistent or even well-constrained relationships among carbon (C), nitrogen (N) and phosphorus (P) in soils, we have endeavored to explore general soil C:N:P ratios in ...
International Carbon Coordination : Roger Revelle’s legacy in the Intergovernmental Oceanographic Commission
(Oceanography Society, 2010-09)
Since its inception in 1960, the Intergovernmental Oceanographic Commission (IOC) has been responsible for organizing and coordinating the scientific investigation of ocean carbon. Roger Revelle (Scripps Institution of ...
Nitrogen dynamics in a small arctic watershed: retention and downhill movement of 15N
We examined short- and long-term nitrogen (N) dynamics and availability along an arctic hillslope in Alaska, USA, using stable isotope of nitrogen (15N), as a tracer. Tracer levels of 15NH4+ were sprayed once onto the ...
The Amazon frontier of land-use change : croplands and consequences for greenhouse gas emissions
(American Meteorological Society, 2010-10-28)
The Brazilian Amazon is one of the most rapidly developing agricultural frontiers in the world. The authors assess changes in cropland area and the intensification of cropping in the Brazilian agricultural frontier state ...
Soil respiration at mean annual temperature predicts annual total across vegetation types and biomes
(Copernicus Publications on behalf of the European Geosciences Union, 2010-07-09)
Soil respiration (SR) constitutes the largest flux of CO2 from terrestrial ecosystems to the atmosphere. However, there still exist considerable uncertainties as to its actual magnitude, as well as its spatial and interannual ...
Controls on nitrogen cycling in terrestrial ecosystems : a synthetic analysis of literature data
(Ecological Society of America, 2005-05)
Isotope pool dilution studies are increasingly reported in the soils and ecology literature as a means of measuring gross rates of nitrogen (N) mineralization, nitrification, and inorganic N assimilation in soils. We ...
Carbon, water, and energy fluxes in a semiarid cold desert grassland during and following multiyear drought
(American Geophysical Union, 2010-11-18)
The net exchanges of carbon dioxide, water vapor, and energy were examined in a perennial Colorado Plateau grassland for 5 years. The study began within a multiyear drought and continued as the drought ended. The grassland ...
