Bas van Geel (1947) is a Quaternary paleoecologist/paleoclimatologist who studied Late Glacial and Holocene lake deposits, fens, bogs and archaeological sites. During the last 40 years links were made between paleoecology, paleoclimatology, environmental archeology and isotope physics. In palynological studies van Geel also explored non-pollen palynomorphs, in combination with macrofossil analysis. Among the newly distinguished non-pollen palynomorphs are representatives of cyanobacteria, fungi and algae.

Van Geel published, together with the isotope physicist Mook, the perspectives of  14C wiggle-match dating of organic deposits. Although initially from a theoretical point of view, they already realised the potential value of this dating strategy. Not only because dating of organic deposits would become more precise, but especially because making a direct link between sediment and peatbog studies and changes in atmospheric 14C concentration (mainly brought about by changing solar activity) would allow a step forward to be made in understanding climate change in the past. Together with van der Plicht (Groningen) considerable progress was made in understanding solar forcing as a factor in climate change. It became evident that the Subboreal-Subatlantic climatic transition (850 yr BC) was triggered by a sudden decline of solar activity, and the socio-economic effects of that climatic change for Late Bronze Age farming communities in areas that were already marginal from a hydrological point ofview becameevident. Also the expansion of the Central Asian horse-riding Scythian culture could be linked to the abrupt climatic shift around 850 yr BC. Summarising the research by van Geel concerns two (connected) main lines:

1. exploration of the paleoecological indicator value of all available microfossils and macrofossils in fine-resolution palynological studies of lake deposits, fens, bogs and archaeological sites. 
2. 14C wiggle-match dating and the study of ∆14C as a climate proxy (solar forcing of climate change and climatic teleconnections).
