Abstract The present research deals with carbon sequestration, as an important process for mitigating the effects of climate change. The investigation focuses on a 30-year period and it covers only aboveground biomass that builds up from natural forest regrowth, excluding any plantation techniques. Potential carbon sequestration rate from natural forest regrowth in Godech Municipality was measured in Mg C ha−1 yr−1 and the resolution of the map was 1x1 km. The results of the study display that carbon accumulation values in the researched area were consistent with those that were expected in the largest parts of Bulgaria. The biggest share of Godech Municipality falls within the range of 0.82 – 0.96 Mg C ha−1 yr−1 with restricted areas around the villages of Barlya, Smolcha, Gubesh, Murgash and Varbnitsa that may accumulate between 0.96 – 1.11 Mg C ha−1 yr−1. In conclusion, carbon accumulation only from natural forest regrowth provides representative information, however it would have been better if different plantation techniques were regarded as well. The successful results of the investigation should encourage other studies of this type in the neighbouring municipalities.

Abstract In the previous study, greenhouse gas CO2 is successfully used as the precipitator to realize its carbonation by calcium ions in seawater with the help of magnesium oxide. In this study, the reaction process is firstly analysed by proposed reaction mechanism, and then the dynamic simulation of the gas-liquid-solid system was carried out via Kinetic Monte Carlo simulation. Based on the reaction mechanism, the continuous experimental study was realized in a bubble column. The effects of air flow rate, carbon dioxide flow rate, temperature on the effectiveness evaluation indexes of decalcification efficiency, total mass transfer coefficient and carbon sequestration rate were studied. Finally, a bonnet tower with a diameter of 1 meter and a height of 8 meters was built to carry out the pilot test. In the laboratory experiments, the calcium removal rate reached 94%, the carbon sequestration rate reached 63.6%, and pure micron calcium carbonate products were obtained. The decalcification rate reached 95% in the pilot test, that is consistent with the results of the laboratory experiment.

Impacts Of Climate Change

Chapter 9 addresses the impacts of climate change and ocean acidification on the marine environment and the extent to which international law has reacted to this emerging threat to the ecological integrity of the oceans. These issues are particularly challenging to regulate because of their wide-ranging causes and effects. This chapter, therefore, takes into account both how the global legal regime relating to climate change, including the United Nations Framework Convention on Climate Change and the Paris Agreement, has taken into account the oceans, as well as how sectoral treaties dealing with specific maritime activities have addressed climate change and ocean acidification within their normative framework. In this latter respect, the chapter focuses on the global regulation of carbon emissions from shipping and the way in which the international community has responded to proposed carbon sequestration activities at sea, including sub-seabed storage and geo-engineering.

Carbon Sequestration Rate

Abstract. Peatlands are a major terrestrial carbon store and a persistent natural carbon sink during the Holocene, but there is considerable uncertainty over the fate of peatland carbon in a changing climate. It is generally assumed that higher temperatures will increase peat decay, causing a positive feedback to climate warming and contributing to the global positive carbon cycle feedback. Here we use a new extensive database of peat profiles across northern high latitudes to examine spatial and temporal patterns of carbon accumulation over the past millennium. Opposite to expectations, our results indicate a small negative carbon cycle feedback from past changes in the long-term accumulation rates of northern peatlands. Total carbon accumulated over the last 1000 yr is linearly related to contemporary growing season length and photosynthetically active radiation, suggesting that variability in net primary productivity is more important than decomposition in determining long-term carbon accumulation. Furthermore, northern peatland carbon sequestration rate declined over the climate transition from the Medieval Climate Anomaly (MCA) to the Little Ice Age (LIA), probably because of lower LIA temperatures combined with increased cloudiness suppressing net primary productivity. Other factors including changing moisture status, peatland distribution, fire, nitrogen deposition, permafrost thaw and methane emissions will also influence future peatland carbon cycle feedbacks, but our data suggest that the carbon sequestration rate could increase over many areas of northern peatlands in a warmer future.
