natural variations that would occur even if humans were absent. Information regarding the pre-anthropogenic state of the Holocene can be obtained either from proxies that record past climate and environmental

strong influence of humans on the natural conditions. To understand the climate system prior to anthropogenic influence, we have to follow another path and employ methods of paleoclimatology. Proxies provide

biomarker-based reconstruction of sea ice, which provides important information on: natural (non-anthropogenically induced) sea ice variability and associated climate variability; Changes in marine primary

and biological pumps of carbon will shift in future, hence whether changes in climate due to anthropogenic greenhouse gas emissions will be amplified or dampened. As physical oceanographers we are inv [...] that the Weddell Sea bottom water became warmer during the last decades, and that its content of anthropogenic CO2 increased continuously; by detailed investigations it could be shown that the densest part

The North Sea is one of the most heavily used seas in the world. Shipping, fishing and other anthropogenic activities have substantial effects on natural ecosystems, while also influencing the North Sea’s
