Discrete air samples were also collected in 4-L Pyrex flasks during these cruises in order to carry out δ 13 C analyses on atmospheric CO 2 . The results acquired between New Zealand and Antarctica are reported here. The mean growth rate of the CO 2 concentration from 1996 to 2003 in ...
Your analysis confirms that CO2 emission has been increased linearly and therefore CO2 concentration has been increasing quadratically. The correct title should be "Linear increase in CO2 emissions will result in a quadratic increase in CO2 concentration. This posting did not consider the outflow ...
To significantly reduce atmospheric CO2 concentration and counteract climate change and its consequences, CO2 emissions must be actively reduced. It is well-known that a significant mitigation of anthropogenic CO2 emissions alone is not sufficient (Fawzy et al. 2020). However, a broad range of ...
Note that the ocean biogeochemistry and simulated atmospheric CO2 concentration are diagnostic, such that there is no feedback onto the simulated physical climate21. Further details on drift adjustment and anomaly generation can be found in the following section. The reconstruction simulation was run ...
An interesting aspect of the observed rise of atmospheric CO2 is that it indicates the greater the CO2 concentration, the faster the “extra” CO2 is removed by biological activity. The observed annual rate of removal is 2.3% of the excess above a baseline of 295 ppm. The greater the “exc...
PNV has already been integrated in conservation planning, forest management or research on the impact of atmospheric CO2 concentration on vegetation (e.g. Lexer et al., 2002, Notaro et al., 2005, Ricotta et al., 2002). The C storage in forest ecosystems is determined by climate (Luyssae...
1. Introduction CO2 is the major anthropogenic greenhouse gas (GHG) in the atmosphere. Its atmospheric concentration has increased to 384 ppm in 2007 from its pre-industrial level of ca. 280 ppm, and is expected to reach 550 ppm by 2050 even if CO2 emission is stable for the next four ...
