Quantifying airborne fraction trends and the destination of anthropogenic CO 2 by tracking carbon flows in a simple climate model
Atmospheric carbon dioxide (CO 2 ) concentrations have increased as a direct result of human activity and are at their highest level over the last 2 million years, with profound impacts on the Earth system. However, the magnitude and future dynamics of land and ocean carbon sinks are not well understood; therefore, the amount of anthropogenic fossil fuel emissions that remain in the atmosphere (the airborne fraction) is poorly constrained. This w…
Carbon flux estimates are sensitive to data source
A large literature exists on mechanisms driving soil production of the greenhouse gases CO 2 and CH 4 . Although it is common knowledge that measurements obtained through field studies vs. laboratory incubations can diverge because of the vastly different conditions of these environments, few studies have systematically examined these patterns. These data are used to parameterize and benchmark ecosystem- to global-scale models, which are then sus…
Carbon cycling in mature and regrowth forests globally
Forests are major components of the global carbon (C) cycle and thereby strongly influence atmospheric carbon dioxide (CO 2 ) and climate. However, efforts to incorporate forests into climate models and CO 2 accounting frameworks have been constrained by a lack of accessible, global-scale synthesis on how C cycling varies across forest types and stand ages. Here, we draw from the Global Forest Carbon Database, ForC, to provide a macroscopic overv…
Inferring the effects of partial defoliation on the carbon cycle from forest structure
In this Perspective, we marshal ground-based canopy and C flux data, and spaceborne Landsat observations of an experimental manipulation of partial canopy defoliation (Gough et al., 2013), to highlight challenges and opportunities in the remote detection and characterization of moderate severity disturbances and their effects on the C cycle
GCAM v5.1
This paper describes GCAM v5.1, an open source model that represents the linkages between energy, water, land, climate, and economic systems. GCAM is a market equilibrium model, is global in scope, and operates from 1990 to 2100 in 5-year time steps. It can be used to examine, for example, how changes in population, income, or technology cost might alter crop production, energy demand, or water withdrawals, or how changes in one region's demand f…
Integrated human-earth system modeling—state of the science and future directions
Research on humans and the Earth system has historically occurred separately, with different teams and models devoted to each. Increasingly, however, these communities and models are becoming intricately linked. In this review, we survey the literature on integrated human-Earth system models, quantify the direction and strength of feedbacks in those models, and put them in context of other, more frequently considered, feedbacks in the Earth syste…
Impact of fire on global land surface air temperature and energy budget for the 20th century due to changes within ecosystems
Fire is a global phenomenon and tightly interacts with the biosphere and climate. This study provides the first quantitative assessment and understanding of fire’s influence on the global annual land surface air temperature and energy budget through its impact on terrestrial ecosystems. Fire impacts are quantified by comparing fire-on and fire-off simulations with the Community Earth System Model (CESM). Results show that, for the 20th century av…
Regional contribution to variability and trends of global gross primary productivity
Biomass offsets little or none of permafrost carbon release from soils, streams, and wildfire
As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by increased production of Arctic and boreal biomass; however, the lack of robust estimates of net carbon balance increases the risk of further overshooting international emissions targets. Precise empirical or model-based assessments of t…
Running an open experiment
Researchers in soil and ecosystem science, and almost every other field, are being pushed—by funders, journals, governments, and their peers—to increase transparency and reproducibility of their work. A key part of this effort is a move towards open data as a way to fight post-publication data loss, improve data and code quality, enable powerful meta- and cross-disciplinary analyses, and increase trust in, and the efficiency of, publicly-funded r…

A global map of urban extent from nightlights
Urbanization, a major driver of global change, profoundly impacts our physical and social world, for example, altering not just water and carbon cycling, biodiversity, and climate, but also demography, public health, and economy. Understanding these consequences for better scientific insights and effective decision-making unarguably requires accurate information on urban extent and its spatial distributions. We developed a method to map the urban…
Global vegetation model diversity and the risks of climate-driven ecosystem shifts
Climate change is modifying global biogeochemical cycles, and is expected to exert increasingly large effects in the future. How these changes will affect and interact with the structure and function of particular ecosystems is unclear, both because of scientific uncertainties and the very diversity of global vegetation models in use. Writing in ERL, Warszawski et al (2013 Environ. Res. Lett. 8 044018) aggregate results from a group of models, ac…
Sensitivity of climate mitigation strategies to natural disturbances
The present and future concentration of atmospheric carbon dioxide depends on both anthropogenic and natural sources and sinks of carbon. Most proposed climate mitigation strategies rely on a progressive transition to carbon-efficient technologies to reduce industrial emissions, substantially supported by policies to maintain or enhance the terrestrial carbon stock in forests and other ecosystems. This strategy may be challenged if terrestrial se…
Rcp4.5
Representative Concentration Pathway (RCP) 4.5 is a scenario that stabilizes radiative forcing at 4.5 W m −2 in the year 2100 without ever exceeding that value. Simulated with the Global Change Assessment Model (GCAM), RCP4.5 includes long-term, global emissions of greenhouse gases, short-lived species, and land-use-land-cover in a global economic framework. RCP4.5 was updated from earlier GCAM scenarios to incorporate historical emissions and la…
Implications of Limiting CO 2 Concentrations for Land Use and Energy
The Power of Green Carbon dioxide is produced both by fossil fuel burning and by deforestation and other land-use changes. Limiting both sources of CO 2 is necessary if we are to curb global warming. Wise et al. (p. 1183 ) use an integrated assessment model to explore the consequences of limiting atmospheric CO 2 concentrations at levels between 450 and 550 parts per million through a combination of fossil-fuel emissions reductions and land-use m…
