23 paź 2020 · Key Points. 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.
1 gru 2019 · The stable isotopes of carbon (δ 13 C) track changes in photosynthesis, respiration, organic matter decomposition and anthropogenic fuel emission inputs (e.g., McDowell et al., 2008), while the oxygen isotopes of water (δ 16 O and δ 18 O) contain information on the linkages between the carbon and water cycles (Dawson and Simonin, 2011).
18 sie 2023 · Carbon isotopes can be used to study the sources and sinks of CO2 in the atmosphere, and to understand the role of different types of vegetation in the carbon cycle. Oxygen isotopes can be used to study the sources and sinks of water vapor in the atmosphere, and to understand the effects of climate change on precipitation patterns.
