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.
The 2019 Hans Oeschger Medal is awarded to Edward J. Brook for producing greenhouse-gas records from polar ice cores in unprecedented resolution that permitted the precise north-south synchronisation of climate signals and the identification of past variations in great detail.
The 2019 Milutin Milankovic Medal is awarded to Jacques Laskar for fundamental contributions to the investigation of orbital climate forcing, and for the development of long-term, reliable astronomical solutions important for the whole palaeoclimate community.

One often hears that ambitious climate policy might be premature while climate change is still “uncertain”. This sounds like a fair argument: The amount of global warming per doubling CO2 is not well constrained, and the amount of economic damage per degree of warming even less. But is this uncertainty a sound excuse to wait and see? Uncertainty, risk aversion, and insurance If you knew the winning combination of this week’s lottery, you would surely buy a lot. If you …
Reconstructing past climate states from geological records is crucial for understanding the causal mechanisms that originated them. These can occur at time-scales which are much longer than the periods for which humans have been measuring climate variables such as temperature in meteorological stations. Such climate reconstructions provide a long-term context to the magnitude of the current anthropogenic (man-made) climate change and are used to evaluate climate models that predict future climate states. For the past few decades, research groups have …
Numerical models are omnipresent in climate research. Constructed to understand the past, to forecast future climate and to gain new knowledge on natural processes and interactions, they enable the simulation of experiments at otherwise unreachable time and spatial scales. These instruments have long been considered to be fed – let even determined – by either theories or observations alone. But are they really? Sociological factors are at play too. It is precisely these influences that the present blog entry attempts …

Magnetism is a physical property that results from the behaviour of elementary particles in any substance. Depending on the chemical composition and distribution of elements within the material, different kinds of magnetism may result. In environmental magnetism mainly …
This month the EGU held its first science-policy pairing scheme, during which a Union member provided scientific testimony and worked alongside a Member of the European Parliament for two days in Brussels. We also published a new policy report summarising the key outcomes from EGU's 2019 science policy event, Shaping EU Missions: bridging the gap between geoscience and policy, held in Brussels in October.
In other news, we have opened the call for applications for EGU Public Engagement Grants (due 15 February 2020) and for EGU Galileo Conference proposals (due 29 February 2020). We also announced a job vacancy at the Union office for a Chief Strategy & Finance Officer. The deadline for applications is 8 January 2020.
