[1] Dissolution of fossil fuel CO2 in seawater results in decreasing carbonate ion concentration and lowering of seawater pH with likely negative impacts for many marine organisms. We project detectable changes in carbonate dissolution and evaluate their potential to mitigate atmospheric CO2 and ocean acidification with a global biogeochemistry model HAMOCC forced by different CO2 emission scen...

The removal of CO2 through chemical absorption in a bench-scale spray dryer absorber was investigated experimentally using the lime slurry as absorbent. The effect of important operating parameters on CO2 removal efficiency has been investigated; in selected ranges of operating parameters, increasing gas inlet temperature and absorbent concentration lead to permanent efficiency decline, increas...

Global atmospheric carbon dioxide (CO2) concentration from fossil fuel combustion has generated much concern because of the several environmental issues associated with high levels of atmospheric CO2, a major greenhouse gas. In order to reduce the risks associated with global warming, the increase in atmospheric CO2 concentration must be prevented. CO2 capture and conversion not only mitigates ...

Exposure to CO2 at high concentration is a much debated stunning method in pigs. Pigs respond aversively to high concentrations of CO2, and there is uncertainty about what behaviors occur before and after loss of consciousness. The aim was to assess timing of unconsciousness in pigs during exposure to high concentrations of CO2 based on changes in electroencephalogram (EEG) activity and the rel...

This research improves our understanding of the Stock-Flow (SF) Failure, found to be a robust problem in the perception of accumulation (Cronin, Gonzalez, & Sterman, 2009). We demonstrate the SF Failure with an interactive simulation in a relevant climate change context (Dynamic Climate Change Simulator (DCCS). In DCCS the climate change problem was simplified to an accumulation (stock), CO2 co...

A small concentration of organic acid in carbon dioxide (CO2) storage formations and caprocks could significantly alter the wettability such into less water-wet conditions, decreasing CO2-storage potential containment security. Recent studies have attempted to infer influence on rock–CO2–brine systems by measuring advancing receding contact angles. However, no investigated contamination capacit...

The stoichiometric ratio of O2 evolution to CO2 uptake during photosynthesis reveals information about reductive metabolism, including the reduction of alternative electron acceptors, such as nitrite and oxaloacetate. Recently we reported that in simultaneous measurements of CO2 uptake and O2 evolution in a sunflower leaf, O2 evolution changed by 7% more than CO2 uptake when light intensity was...
