On the Southern Ocean CO2 uptake and the role of the biological carbon pump in the 21st century, links to supplementary material

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.

The role of the G20 in WTO governance

Report by Professor Sungjoon Cho, Associate Professor of Law, Chicago-Kent College of Law (Chair), and Charlotte Sieber-Gasser, Doctoral Research Fellow, World Trade Institute, University of Bern, Session 27, WTO Public Forum 2010: The Forces Shapping World Trade, pp.29-33. In the course of the financial crisis, the global geography of power has shifted from G8 to G20. The latter, although representing roughly two thirds of global trade, consists of relatively a small number of global players and is consequently excluding many others from decision-making at the international stage. Nevertheless, the G20 has been successful in its reaction to the financial crisis and became therewith an important new player within the international community. When highlighting how the G20 might interfere with the WTO, the panel voiced concerns over the political legitimacy of the G20, given the limited number of members and the global impact of its decisions. It agreed on the impression that although the G20 intends to extend its debates from the financial sector to world economy in general, it has so far little achieved in this direction, particularly when it comes to moving the Doha agenda forward. It remains, thus, open how the G20 will evolve in the coming few years, and what mandates it will shed or adopt. So far, the G20 has complemented the WTO and international financial institutions in handling the financial crisis. Yet, even if there is little evidence pointing towards a less cooperative role in the future, the desirability of a G20 commitment in WTO trade negotiations has yet to be debated. The panel concluded by providing ideas on how the potential of the G20 might be used to serve global interests even better in the future. In their concluding remarks, the panellists agreed that it remains to be seen whether or not the G20 will further broaden its agenda. Given the ebbing away of the financial crisis there is even the question whether the G20 will remain an important international forum for financial collaboration, or whether it has already served its cause and will eventually disappear from the international stage. The Chair concluded the well attended and lively panel with voicing the hope that the two international bodies – the G20 and the WTO – will work in a positive way together in the future and face the challenges and opportunities in their collaboration to the benefit of everyone.
