The firn air δ13C agrees with the Cape Grim record, but only after correction for gravitational separation at depth, for diffusion effects associated with disequilibrium between the atmosphere and firm, and allowance for a latidudinal gradient in δ13C between Cape Grim and the Antarctic coast...
The paper also examines the influence of ocean-atmospheric interactions on the transient response of the climate system, which reveals the deficiencies in present schemes of asynchronously coupling the ocean and the atmosphere in three-dimensional climate models. 展开 ...
“Considering the fact that present human activities, primarily through fossil fuel burning, are releasing vast quantities of carbon into the Earth’s atmosphere and oceans at a rate never before seen in the geological past, it appears that the world is racing toward another major mass extinction...
As shown in Fig.5, TGA measurements were conducted in an air atmosphere from 40 to 750 °C to determine the thermal stability of UIO-66-NH2. The sample loses approximately 9.93% of its weight at 20–131 °C due to moisture. It has been found that weight loss is approximately 6.89 and...
to show two irreversible reductive peaks, which might correspond to the reduction of adduct1–1at the cathodic surface (Fig.7c)62. Furthermore, two new reductive peaks at −1.86 V (Ep) and −2.27 V (Ep) were emerged when adduct1–1was present in the CO2atmosphere, which migh...
In this sense, production and conversion of synthesis gas (SYNGAS) exhibits the highest potential for medium term of commercial success. Nevertheless, it is worth noting that, while the utilization of CO2 has potential to reduce greenhouse gas emissions into the atmosphere, CO2 has disadv...
We present here first results of (CO2)-C-14 monitoring at two sampling sites in the equatorial region of the South American continent (station Aychapicho, Ecuador and station Llano del Hate, Venezuela). We also include the data for two other stations representing undisturbed marine atmosphere at...
The concentration of CO2 in the atmosphere has increased from approximately 277 ppm in 1750 (Joos and Spahni, 2008) at the beginning of the industrial era, to 410.5 ppm in 2019 (WMO, 2020). The increase in anthropogenic emission of greenhouse gases (GHGs), in combination with other anthropo...
From atmosphere of airtightness residence possible environment carbon dioxide (CO2) the device which is absorbed, manner and absorbentA regenerable high capacity carbon dioxide (CO2) sorbent is operated to remove substantially all of the CO2 present in either a dry, or a humid environment. The ...
While CO2 concentrations in the atmosphere have fluctuated throughout time, the rate of increase recorded since the 1850s is greater than any rate of increase that has occurred in the last million years2. As CO2 in the atmosphere rises, dissolution of CO2 into the ocean increases, thus ...
