The Division on Climate: Past, Present & Future is one of the larger divisions of the European Geosciences Union. It pools from many disciplines and consequently has many co-organized and co-listed sessions with other divisions at the general assembly. The division is very interdisciplinary and covers climate variations on all time scales. CL includes the study of any kind of climate archive from rocks to ocean cores, speleothems, ice cores, chronicles, to instrumental records to name a few. Besides observations, climate modeling on all time scales from the deep past to the future are areas covered by the division. Any aspect of the climate system falls into the realm of the division e.g. atmosphere, ocean, biosphere, cryosphere, and geology. Themes focus on the climate on Earth but may also expand other planets or the sun.
Obituary: John Kutzbach
EGU is saddened to report the death of John Kutzbach, a Professor Emeritus in the Department of Atmospheric and Oceanic Sciences and former Director of the Center for Climatic Research at University of Wisconsin-Madison. Kutzbach was awarded EGU’s Milankovich Medal in 2001 for his “pioneering and outstanding contributions towards the understanding of the response of the climate system to astronomical forcing using three-dimensional ocean-atmosphere models”.
The following tribute was written by Bette Otto-Bliesner in his honour:
Kutzbach’s career centered around using climate models to study previous as well as future climates. His colleagues at the university shared that “Professor Kutzbach’s pioneering use of general circulation models for climate research broke ground for future generations of climate scientists to study past, present, and future aspects of our Earth system. His interdisciplinary work with geologists, geochemists, palaeoecologists, glaciologists, archaeologists, and hydrologists helped identify, and ultimately improve, the quality of the output of the climate models that current Earth system scientists use to develop climate projections."
In recent years, Kutzbach’s work has focused on the impacts of climate and climate change on natural resources and society; past climates and past environments; how humans have contributed to climate change; and present-day climate variability and simulations of future climate changes.
In 2006, AGU awarded Kutzbach the Roger Revelle Medal, citing his body of work that “forms a large part of the framework of our current understanding of past climates”. He was a member of the National Academy of Sciences and Fellow of AGU, AMS, and the American Association for the Advancement of Science.
John is survived by his wife, Professor Gisela Hanebuth Kutzbach, their three children, and six grandchildren.
On a personal note, John started me, soon after my PhD, on modeling past climates, a rewarding focus that has taken me down a path of many new and intriguing challenges and exciting interdisciplinary collaborations. He was a mentor, a colleague, and a friend.

The Anthropocene Working Group (AWG) is the body tasked to propose a formal definition for the Anthropocene as a geological time unit. Join us at the EGU2021 General Assembly on Wednesday 28th April at 14:15-15:00 CEST for a series of presentations on the Anthropocene in session SSP2.6. The Anthropocene concept Geologists cope with the enormity of 4.5 billion years of Earth history by dividing it into named geological time units which have globally specific starts and ends. Each unit’s characteristics …
More than 11 years ago, I joined the Université catholique de Louvain (UCLouvain) in Belgium as a teaching assistant. The 2007-2009 International Polar Year (IPY), a worldwide collaborative effort aiming at better understanding our polar regions, had just finished, and the scientific community was concerned about the sudden drop in the summer Arctic sea ice extent that had occurred two years before (2007). This event had literally taken everyone by surprise! The same year, the Fourth Assessment Report (AR4) of …
Loess is a silt-sized, aeolian sediment that was produced in large quantities in past geological eras of mid-latitude Europe and Asia, among others (Fig. 1). It is used in Quaternary science to infer about past climatic and environmental conditions. Generally, layers of loess formed during cold and dry periods, while soils formed within/on top the loess during warmer and wetter periods. These soils get buried again under a new loess layer once the warmer period is over. Since these soils …
One of the most profound consequences of past climate changes are the geologically rapid (<100,000 year) changes in global topography. For thousands of years, large ice sheets, similar to what currently exists in Greenland and Antarctica, waxed and waned on North America and Europe. Only 20,000 years ago, if you were sitting in the middle of Canada or Sweden, you would be under thousands of meters of ice (Figure 1). Changes of the Earth’s surface at this scale had many …
