Carbon Cycle and Climate Change As climate change accelerates, it is important to know the likely impact of climate change on the carbon cycle (see the Perspective by Reich). Gross primary production (GPP) is a measure of the amount of CO2 removed from the atmosphere every year to fuel photosynthesis. Beer et al. (p. 834, published online 5 July) used a combination of observation and calculation to estimate that the total GPP by terrestrial plants is around 122 billion tons per year; in… Expand

Two papers in this issue contribute to understanding the land-atmosphere exchange by elegantly analyzing rich data sets on CO2 fluxes from a global network of monitoring sites. Expand
Recent increases in terrestrial carbon uptake at little cost to the water cycle
It is suggested that rising atmospheric CO2 concentration has caused a shift in terrestrial water economics of carbon uptake, and that this increase is largely driven by increased water-use efficiency, rather than an increase in water use. Expand
Large historical growth in global terrestrial gross primary production
This work presents a global, measurement-based estimate of GPP growth during the twentieth century that is based on long-term atmospheric carbonyl sulfide records, derived from ice-core, firn and ambient air samples, and interprets these records using a model that simulates changes in COS concentration according to changes in its sources and sinks. Expand
Global covariation of carbon turnover times with climate in terrestrial ecosystems
A global, spatially explicit and observation-based assessment of whole-ecosystem carbon turnover times that combines new estimates of vegetation and soil organic carbon stocks and fluxes finds that the overall mean global carbon turnover time is  years (95 per cent confidence interval). Expand
Water use efficiency of net primary production in global terrestrial ecosystems
The carbon and water cycles of terrestrial ecosystems, which are strongly coupled via water use efficiency (WUE), are influenced by global climate change. To explore the relationship between theExpand
Evolution of hydrological and carbon cycles under a changing climate
Hydrological and carbon cycles are inherently coupled and play a pivotal role in the earth system. Water stress is one of the most limiting factors constraining vegetation productivity in both directExpand
Carbon cycle: A dent in carbon's gold standard
Analysis of nearly 30 years of unpublished records of the oxygen isotope (18O/16O) composition of atmospheric carbon dioxide from sampling sites worldwide has provided a means of estimating the GPP that is not reliant on modelling, and reveals previously unrecognized interannual fluctuations that are driven by El Nino climate events. Expand
Sensitivity of atmospheric CO2 growth rate to observed changes in terrestrial water storage
It is shown that theCO2 growth rate is strongly sensitive to observed changes in terrestrial water storage, drier years being associated with faster atmospheric CO2 growth, and this relationship is underestimated in current carbon cycle models. Expand
Terrestrial Carbon Cycle Variability
How variable the carbon cycle is, how large the trends in its gross and net fluxes are, and how well the signal can be separated from noise are reviewed are reviewed. Expand
Natural Carbon Sequestration by Forestry
Carbon dioxide (CO2) levels have been rapidly rising in the atmosphere following the beginning of industrialisation and reaching new highs in the last recent years. Global carbon cycle studiesExpand


‘Breathing’ of the terrestrial biosphere: lessons learned from a global network of carbon dioxide flux measurement systems
Key findings reported include: ecosystems with the greatest net carbon uptake have the longest growing season, not the greatest FA; many old-growth forests act as carbon sinks; and year-to-year decreases in FN are attributed to a suite of stresses that decrease FA and FR in tandem. Expand
CO2 Balance of Boreal, Temperate, and Tropical Forests Derived from a Global Database
Terrestrial ecosystems sequester 2.1 Pg of atmospheric carbon annually. A large amount of the terrestrial sink is realized by forests. However, considerable uncertainties remain regarding the fate ofExpand
Climate-carbon cycle feedback analysis: Results from the C
Eleven coupled climate–carbon cycle models used a common protocol to study the coupling between climate change and the carbon cycle. The models were forced by historical emissions and theExpand
The impact of soil microorganisms on the global budget of δ18O in atmospheric CO2
This enhanced soil hydration increases the differences between the isotopic signatures of photosynthesis and respiration, particularly in the tropics, increasing the precision of CO2 gross fluxes obtained by using the δ18O of atmospheric CO2 by 50%. Expand
Carbon allocation in forest ecosystems
Carbon allocation plays a critical role in forest ecosystem carbon cycling. We reviewed existing literature and compiled annual carbon budgets for forest ecosystems to test a series of hypothesesExpand
Modelling the role of agriculture for the 20th century global terrestrial carbon balance
In order to better assess the role of agriculture within the global climate-vegetation system, we present a model of the managed planetary land surface, Lund-Potsdam-Jena managed Land (LPJmL), whichExpand
A three‐dimensional synthesis study of δ18O in atmospheric CO2 1. Surface fluxes
The isotope O-18 in CO2 is of particular interest in studying the global carbon cycle because it is sensitive to the processes by which the global land biosphere absorbs and respires CO2. CarbonExpand
Forest carbon use efficiency: is respiration a constant fraction of gross primary production?
Carbon-use efficiency (CUE), the ratio of net primary production (NPP) to gross primary production (GPP), describes the capacity of forests to transfer carbon (C) from the atmosphere to terrestrialExpand
Temporal and among-site variability of inherent water-use efficiency at the ecosystem level
Half-hourly measurements of the net exchanges of carbon dioxide and water vapor between terrestrial ecosystems and the atmosphere provide estimates of gross primary production (GPP) andExpand
Climate-Driven Increases in Global Terrestrial Net Primary Production from 1982 to 1999
It is indicated that global changes in climate have eased several critical climatic constraints to plant growth, such that net primary production increased 6% (3.4 petagrams of carbon over 18 years) globally. Expand
