The European Union (EU) is widely acknowledged as a successful example of economic and political integration of nation states today – a slate of democratic institutions such as the European Parliament have also been developed and European citizens now possess extensive political and civil rights by virtue of the introduction of European citizenship. Nevertheless, the EU is said to suffer from a so called “democratic deficit” even as it seeks deeper and closer integration. Decades of institutional design and elite closed-door decisions has taken its toll on the inclusion and integration of European citizens in social and political life, with widening socio-economic inequalities and the resurgence of extreme-right parties during in the wake of the debt crisis in the Eurozone. This paper attempts to evaluate the democratic development of the EU through the use of a process-oriented approach, and concludes at the end with discussions on the various options that the EU and its citizens can take to reform democratic processes and institutions in Europe.

We use a suite of eight ocean biogeochemical/ecological general circulation models from the MAREMIP and CMIP5 archives to explore the relative roles of changes in winds (positive trend of Southern Annular Mode, SAM) and in warming- and freshening-driven trends of upper ocean stratification in altering export production and CO2 uptake in the Southern Ocean at the end of the 21st century. The investigated models simulate a broad range of responses to climate change, with no agreement ona dominance of either the SAM or the warming signal south of 44° S. In the southernmost zone, i.e., south of 58° S, they concur on an increase of biological export production, while between 44 and 58° S the models lack consensus on the sign of change in export. Yet, in both regions, the models show an enhanced CO2 uptake during spring and summer. This is due to a larger CO 2 (aq) drawdown by the same amount of summer export production at a higher Revelle factor at the end of the 21st century. This strongly increases the importance of the biological carbon pump in the entire Southern Ocean. In the temperate zone, between 30 and 44° S all models show a predominance of the warming signal and a nutrient-driven reduction of export production. As a consequence, the share of the regions south of 44° S to the total uptake of the Southern Ocean south of 30° S is projected to increase at the end of the 21st century from 47 to 66% with a commensurable decrease to the north. Despite this major reorganization of the meridional distribution of the major regions of uptake, the total uptake increases largely in line with the rising atmospheric CO2. Simulations with the MITgcm-REcoM2 model show that this is mostly driven by the strong increase of atmospheric CO2, with the climate-driven changes of natural CO2 exchange offsetting that trend only to a limited degree (~10%) and with negligible impact of climate effects on anthropogenic CO2 uptake when integrated over a full annual cycle south of 30° S.
