Biography
Dorthe Dahl-Jensen received the M.Sc. and Ph.D. degrees in geophysics from the University of Copenhagen, Copenhagen, Demark, in 1984, and 1988, respectively.
She is currently a Professor with the Niels Bohr Institute, University of Copenhagen, and the Canada Excellence Research Chair with the Centre for Earth Observation Science, University of Manitoba, Winnipeg, MB, Canada. Her major scientific achievements have been in leading ice core drilling and subsequent analysis of ice core data in conjunction with models to determine past climate and how it affected the Greenland ice sheet. She has led several international deep drilling projects, such as NGRIP, NEEM, and EGRIP. In addition, she has led large research projects funded by grants from the Danish National Research Foundation (DNRF), European Research Council (ERC), EU FP7, Villum Investigator, and Canada Excellence Research Chair. The research has led to numerous achievements and here are some highlights to illustrate how the past illuminates potential future abrupt climate changes. During the Last Interglacial where Greenland temperatures were 5 °C warmer than the present, the Greenland ice sheet thinned and contributed to the global sea level rise by about 2 m. Dated Greenland ice cores through the past 2000 years show the impact on the atmosphere from human activities, such as forest burning and industrialization, and from volcanic eruptions producing aerosols that cool the Earth surface for about ten summers following the event. Synchronized ice cores from Greenland and Antarctica show 25 very abrupt climate changes during the last glacial and modeling shows that the events represent internal movement of energy through ocean and atmosphere between the Northern and Southern hemispheres. The research is very well cited, and five others and she from her research group are Thomson Reuters highly cited researchers.
