Large scale circulation changes as captured by anthropogenic tracers Contact: Michael Karcher The Arctic Ocean surface circulation is characterized by the Transpolar Drift, which carries [...] paths through the Arctic. Such a tracer is 129 Iodine, an anthropogenic radionuclide which is dumped as waste into the Irish Sea and the North Sea by nuclear reprocessing facilities. Measuring the

of 2015, Germany and the global community agreed to limit anthropogenic global warming to less than 2°C. But that goal can only be reached if both national and international agreements are adhered to

of the carbon isotope 14C in the atmosphere accelerated by anthropogenic carbon dioxide emissions and the associated distortion of the radiocarbon age of materials can be precisely identified - by

the concentration of CO 2 in our atmosphere and the extent of anthropogenic climate change would be considerably higher.

. For the purpose of the budget, researchers estimate the anthropogenic carbon budget for the planet as a whole; this includes the sources (emissions), the carbon sinks on land and in the ocean, and

past decades. This warming is to a large extent due to the anthropogenic emissions of CO2 that amplify the natural greenhouse effect. Observations show, however, that there has been hardly or almost
