Throughout the last few decades, scientists have generated a wealth of information from naturally occurring paleorecords of a wide spectrum of environmental and climate parameters which reflect evolution of Earth systems. A fundamental task of Global

Present understanding suggests that a doubling of CO2 emission will occur in about 50 years and will lead to global warming of 2–4°C. Data from the past supports this. The paper analyses the factors influencing climatic change and the challenges t

Air in the bubbles of polar ice has in principal the same composition as the atmospheric air at the time of ice formation. Based on this relationship, an increase in atmospheric CO2 since the beginning of industrialisation has been documented (Neftel

We report a first series of10Be measurements on Chinese loess covering the last 750,000 years. The10Be concentration shows a tendency to decrease with increasing grain size. Leaching experiments with acid solutions show that10Be is strongly bound to

A detailed snow pit study at Dye 3, South Greenland, has been carried out in order to investigate the seasonal variations of 10Be, Cl−, NO3−, SO42−, H2O2, 210Pb, 3H, Mn and σ18O. Special emphasis was placed on understanding the causes of 10Be

10 Be is produced in a similar way as 14 C by the interaction of cosmic radiation with the nuclei in the atmosphere. Assuming that the 10 Be and 14 C variation are proportional and considering the different behaviour in the Earth system, the 10 Be co
