The measured tracers were used to quantify the contribution of biomass burning (0.6–0.9ngCm 3), vegetative detritus (0.3–0.9ngCm 3), and fossil fuel combustion (0.1–0.8ngCm 3) sources, 4% of OC total, to atmospheric organic carbon concentrations at the remote location of Summit, Green...
Efforts to control climate change require the stabilization of atmospheric carbon dioxide concentrations. An assessment of the trends in sources and sinks of atmospheric carbon dioxide suggests that the sinks are not keeping up with the increase in carbo

carbon dioxide. Impacts from ocean acidification are included in this review in the same regard. Due to the levels of greenhouse gases currently in the atmosphere, the trends of certain CC impacts (e.g., sea level rise6and ocean oxygen loss7) will continue. However, projections on the ...
In recent years, the role of the atmosphere in the formation of the chemical composition of water in Lake Baikal and its tributaries has been increasing. In this regard, the study of equivalent black carbon (eBC) in the air above the lake and its coast has an important practical application...
work, published inGeophysical Research Letters, looks at the effect that large, destructive storms – such as 2016's Hurricane Matthew – have on carbon sinks and on the amount of carbon dioxide (CO2) being released into the atmosphere around North Carolina's Neuse River estuary and Pamlico ...
In this woodland, 47% of the precipitation within a single growing season (May- October) was returned to atmosphere as soil evaporation and the CO2 efflux observed just during the first rainy month (July) was equivalent to almost 50% of the net carbon gain observed over the six-month ...
