    Description: The effects of climate change (CC) on contaminants and their potential consequences to marine ecosystem services and human wellbeing are of paramount importance, as they pose overlapping risks. Here, we discuss how the interaction between CC and contaminants leads to poorly constrained impacts that affects the sensitivity of organisms to contamination leading to impaired ecosystem function, services and risk assessment evaluations. Climate drivers, such as ocean warming, ocean deoxygenation, changes in circulation, ocean acidification, and extreme events interact with trace metals, organic pollutants, excess nutrients, and radionuclides in a complex manner. Overall, the holistic consideration of the pollutants-climate change nexus has significant knowledge gaps, but will be important in understanding the fate, transport, speciation, bioavailability, toxicity, and inventories of contaminants. Greater focus on these uncertainties would facilitate improved predictions of future changes in the global biogeochemical cycling of contaminants and both human health and marine ecosystems.

    Description: The Southern Ocean is one of the key regions for global carbon uptake and it is under discussion how physical changes will alter its CO2 balance both directly and indirectly through changes in biological production. Here we analyse a suite of eight RCP8.5 model simulations until 2100 from the MAREMIP and CMIP5 model intercomparison projects on changes in export production and CO2 uptake. We explore how the counter-acting effects of stronger winds ("SAM signal", less stratification) and global warming (more stratification) affect CO2 fluxes in different models and different regions of the Southern Ocean. The models simulate a broad range of responses with no agreement on the dominance of the SAM or global warming signal or on nutrient or light as the dominant drivers for changes in export production. There is agreement on an increase in export production south of 58◦S and on a nutrient-driven decrease of export production in the region 30-44◦S (global warming signal). Based on a box-model, we can identify the most important drivers for the future CO2 uptake in the Southern Ocean where the pure increase of atmospheric CO2 has the largest effect, followed by the enhanced biological production and the larger effect of biological production on CO2 uptake at higher Revelle factor. The enhanced upwelling of carbon-rich deep water, and the effects of warming on the CO2 solubility and faster gas-exchange at higher wind-speeds are less important.
