Abstract The remaining carbon budget quantifies the future CO 2 emissions to limit global warming below a desired level. Carbon budgets are subject uncertainty in Transient Climate Response Cumulative Emissions (TCRE), as well non-CO climate influences. Here we estimate TCRE using observational constraints, and integrate geophysical socioeconomic uncertainties affecting distribution of budget. ...

[1] Mangrove forests are highly productive but globally threatened coastal ecosystems, whose role in the carbon budget of the coastal zone has long been debated. Here we provide a comprehensive synthesis of the available data on carbon fluxes in mangrove ecosystems. A reassessment of global mangrove primary production from the literature results in a conservative estimate of 218 ± 72 Tg C a . W...

[1] Using an estimated bicarbonate concentration ([HCO3 ]) in water and discharge rates of surface water and underground water from the Houzhai Basin, southwest China, from 1986 to 2007, we estimate that the mean carbon uptake rate was 20.7 g C m yr. The surface water and underground water contribute about equally to the total carbon uptake from 1986 to 2007. About 97% of the interannual variat...

The standard intertemporal model of open economy with a dynamic budget constraint predicts that investment and saving should be cointegrated as long as the economy does not violate its budget constraint. Recent empirical studies of the long run investment-saving comovement for the 1947:1–1987:3 period US data, however, report conflicting findings: some studies find that the time series of inves...

Lal et al. have recently argued (1, 2) that restoring soil carbon levels worldwide is important for a number of purposes, including reducing atmospheric CO 2 concentrations. We agree, but we question how much eroded soil C is ultimately delivered to the atmosphere. Previous estimates of the proportion of eroded soil carbon oxidized range from 0% to near 100% (3, 4). We believe that the true val...

Most previous top-down global carbon monoxide (CO) budget estimates have used only concentration information and shown large differences in individual source estimates. Since CO from certain sources has a specific isotopic signature, coupling the concentration and isotope fraction information can provide a better constraint on CO source strength estimates. We simulate both CO concentration and ...

Forests play a key role in the carbon cycle as they store huge quantities of organic carbon, most of which is stored in soils, with a smaller part being held in vegetation. While the carbon storage capacity of forests is influenced by forestry, the long-term impacts of forest managers' decisions on soil organic carbon (SOC) remain unclear. Using a meta-analysis approach, we showed that conventi...
