Tracking the fate of anthropogenic carbon in the ocean — Modeling the global 13C-Suess effect

Rising fossil-fuel CO2 emissions deplete the atmospheric concentrations of the heavy carbon isotope 13C. This phenomenon, called the 13C Suess effect, can be used to discern the pathways of anthropogenic carbon in the Earth system. In a new study, Dr. Bo Liu, Dr. Katharina D. Six, and Dr. Tatiana Ilyina investigated the sources of uncertainty in an…

New IPCC Assessment Report: Climate change widespread, rapid, and intensifying

How has climate changed up until the present? How will it change in the future? Questions like these are answered in the recently published first part of IPCC´s Sixth Assessment Report, which summarizes the scientific facts about climate change. This first part will be supplemented with two more parts in the coming spring, addressing adaptation to…

Past abrupt changes provide evidence of cascading tipping points and ‘early warning signals’ in the Earth system

Can climate change result in a collapse in parts of the Earth system, what impacts would these events have on society, and can they be predicted? In the article published in Nature Geoscience, an international team of natural and social scientists have reviewed abrupt shifts in the Earth's past in order to sharpen their tools for predicting the…
