Abstract. Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, terrestrial biosphere in a changing climate – “global budget” is important to better understand global cycle, support development policies, project future change. Here we describe synthesize data sets methodology quantify five major components budget uncertainties. Fossil CO2 (EFOS) are based on energy statistics cement production data, while from land-use...

Based on the 2019 assessment of Global Carbon Project, ocean took up average, 2.5+/-0.6PgCyr-1 or 23+/-5% total anthropogenic CO2 emissions over decade 2009-2018. This sink estimate is based global biogeochemical models (GOBMs) and compared to data-products surface pCO2 (partial pressure CO2) observations accounting for outgassing river-derived CO2. Here we evaluate GOBM simulations by comparing simulated observations. The are well suited quantifying carbon time-scale annual mean its...
Abstract. Past model studies have projected a global decrease in marine net primary production (NPP) over the 21st century, but these focused on multi-model mean rather than large inter-model differences. Here, we analyze model-simulated changes NPP for century under IPCC's high-emission scenario RCP8.5. We use suite of nine coupled carbon–climate Earth system models with embedded ecosystem and focus spread between different underlying reasons. Globally, decreases five out course while three...
Measurements show large decadal variability in the rate of [Formula: see text] accumulation atmosphere that is not driven by emissions. The decade 1990s experienced enhanced carbon relative to emissions, while 2000s, atmospheric growth slowed, even though emissions grew rapidly. These variations are natural sources and sinks due ocean terrestrial biosphere. In this study, we compare three independent methods for estimating oceanic uptake find sink could be responsible up 40% observed...

Abstract Fossil fuel combustion, land use change and other human activities have increased the atmospheric carbon dioxide (CO 2 ) abundance by about 50% since beginning of industrial age. The CO growth rates would been much larger if natural sinks in biosphere ocean had not removed over half this anthropogenic . As these emissions grew, uptake response to increases partial pressure (pCO ). On land, gross primary production also increased, but dynamics key aspects cycle varied regionally....
Abstract This contribution to the RECCAP2 (REgional Carbon Cycle Assessment and Processes) assessment analyzes processes that determine global ocean carbon sink, its trends variability over period 1985–2018, using a combination of models observation‐based products. The mean sea‐air CO 2 flux from 1985 2018 is −1.6 ± 0.2 PgC yr −1 based on an ensemble reconstructions history sea surface pCO (pCO products). Models indicate dominant component this net oceanic uptake anthropogenic , which...

Abstract The coastal ocean contributes to regulating atmospheric greenhouse gas concentrations by taking up carbon dioxide (CO 2 ) and releasing nitrous oxide (N O) methane (CH 4 ).

A Happy Marriage The fluxes of CO 2 between the atmosphere and ocean are large variable, understanding why concentration atmospheric changes as it does, depends on accurately determining details those fluxes. One major obstacles in way quantifying this exchange is that there too few measurements available, both temporally geographically. Watson et al. (p. 1391 ) report results from a happy marriage science commerce—data collected by instruments fitted onto commercial ships plying waters...
