23 paź 2020 · Carbon isotopes, 14 C and 13 C, in atmospheric CO 2 are changing in response to fossil fuel emissions and other human activities. Future simulations using different SSPs show continued changes in isotopic ratios that depend on fossil fuel emissions and, for 13 C, BECCS.
3 wrz 2024 · This study emphasizes the importance of monitoring stable isotopes of atmospheric CO2, especially in volcanic areas, contributing valuable insights for environmental and public health...
The atmospheric carbon cycle accounts for the exchange of gaseous carbon compounds, primarily carbon dioxide (CO 2), between Earth's atmosphere, the oceans, and the terrestrial biosphere.
17 sty 2018 · Atmospheric effects must be taken into account when interpreting terrestrial stable carbon isotopes, with important implications for past environments and climates, and understanding plant ...
14 mar 2016 · Over thirty years ago ice cores provided the first clear evidence that atmospheric CO 2 increased by about 75 ppm as Earth transitioned from a glacial to an interglacial state (1, 2). After decades of research, the underlying mechanisms that drive glacial–interglacial CO 2 cycles are still unclear.
28 wrz 2011 · The stable isotope ratios of atmospheric CO 2 (18 O/ 16 O and 13 C/ 12 C) have been monitored since 1977 to improve our understanding of the global carbon cycle, because biosphere–atmosphere...
31 gru 2014 · This chapter reviews the methodological and observational basis underlying the use of the isotopic composition of atmospheric CO2 in tracing and interpreting the changes in sources and sinks...
