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, ...
Consequences of considering carbon–nitrogen interactions on the feedbacks between climate and the terrestrial carbon cycle
(American Meteorological Society, 2008-08-01)
The impact of carbon–nitrogen dynamics in terrestrial ecosystems on the interaction between the carbon cycle and climate is studied using an earth system model of intermediate complexity, the MIT Integrated Global Systems ...

Seasonal use of a New England estuary by foraging contingents of migratory striped bass
(American Fisheries Society, 2009-12-10)
Using acoustic telemetry on migratory striped bass Morone saxatilis in Plum Island Estuary (PIE), Massachusetts, we found that striped bass (335–634 mm total length) tagged in the spring and summer of 2005 (n = 14) and ...
Objective indicators of pasture degradation from spectral mixture analysis of Landsat imagery
(American Geophysical Union, 2008-07-23)
Degradation of cattle pastures is a management concern that influences future land use in Amazonia. However, “degradation” is poorly defined and has different meanings for ranchers, ecologists, and policy makers. Here we ...
Linkages among runoff, dissolved organic carbon, and the stable oxygen isotope composition of seawater and other water mass indicators in the Arctic Ocean
(American Geophysical Union, 2005-12-07)
Concentrations of dissolved organic carbon (DOC) and δ18O values have been determined following sampling of runoff from a number of major arctic rivers, including the Ob, Yenisey, Lena, Kolyma, Mackenzie and Yukon in ...
Effect of historical changes in land use and climate on the water budget of an urbanizing watershed
(American Geophysical Union, 2006-03-25)
We assessed the effects of historical (1931-1998) changes in both land-use and climate on the water budget of a rapidly urbanizing watershed, Ipswich River basin (IRB), in northeastern Massachusetts. Water diversions and ...
Decreased mass specific respiration under experimental warming is robust to the microbial biomass method employed
Hartley et al. question whether reduction in Rmass, under experimental warming, arises because of the biomass method. We show the method they treat as independent yields the same result. We describe why the substrate-depletion ...
Methane fluxes between terrestrial ecosystems and the atmosphere at northern high latitudes during the past century : a retrospective analysis with a process-based biogeochemistry model
(American Geophysical Union, 2008-08-18)
We develop and use a new version of the Terrestrial Ecosystem Model (TEM) to study how rates of methane (CH4) emissions and consumption in high-latitude soils of the Northern Hemisphere have changed over the past century ...
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 ...
