we can alter parameters like light, temperature and nutrients – all of which are affected by anthropogenic climate change in the real world – in a controlled way, which allows us to investigate their impact

analysing historical time series of direct temperature measurements. Information regarding the pre-anthropogenic state of the system can be obtained either by reconstructing the climatic and environmental conditions
and environmental states, as well as the recent reaction of the Earth system on natural and anthropogenic driven climate change. Scientists from Bremerhaven, Potsdam and Sylt are investigating which processes
Global Carbon Budget - Ocean Accurate assessment of anthropogenic carbon dioxide (CO 2 ) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere – the “global carbon budget” [...] land sink have approximately balanced. The oceans are therefore the most important net sink for anthropogenic CO 2 emissions. The ocean in the Global Carbon Budget Less than half of all CO 2 emissions remain [...] land sink have approximately balanced. The oceans are therefore the most important net sink for anthropogenic CO 2 emissions. Each year, we collect estimates of the ocean carbon sink from global ocean bi
of humans on the natural conditions. Therefore, to understand the climate system prior to the anthropogenic influence, we have to follow another path. Proxies (representative data) help us to understand
