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.
15 lis 2020 · Emissions of CO2 from fossil fuel combustion and land use change reduce the ratio of 13C/12C in atmospheric CO2 (δ13CO2). This is because 12C is preferentially assimilated during photosynthesis...
14 mar 2016 · Here we help to constrain changing sources with a high-precision, high-resolution deglacial record of the stable isotopic composition of carbon in CO 2 (δ 13 C-CO 2) in air extracted from ice samples from Taylor Glacier, Antarctica.
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 ...
25 kwi 2016 · A reconstruction of atmospheric CO2 concentration from boron isotopes recorded in planktonic foraminifera examines climate–carbon interactions over the past tens of millions of years and ...
28 wrz 2011 · Abstract. 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...
1 wrz 2013 · Precise measurements of the stable carbon isotopes of atmospheric carbon dioxide (CO 2) provide important information about carbon exchange processes.
