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.
The 2019 Outstanding Student Poster and PICO (OSPP) Awards is awarded to Aline Mega Highly variable surface-water conditions off southern Portugal during mid-Pleistocene Marine Isotope Stages 20 to 26 (790 – 970 ky)
The 2019 Outstanding Student Poster and PICO (OSPP) Awards is awarded to Bernat Jiménez-Esteve Nonlinearity in the Northern Hemisphere atmospheric response to a linear ENSO forcing
The 2019 Outstanding Student Poster and PICO (OSPP) Awards is awarded to Iulia-Madalina Streanga A calibration study of Sr/Ca ratios and δ18O to sea surface temperature and salinity in the West Pacific Warm Pool
The 2019 Outstanding Student Poster and PICO (OSPP) Awards is awarded to Livia Manser Neogene evolution of paleoenvironments in the North American Great Plains from a stable isotope study
The 2019 Outstanding Student Poster and PICO (OSPP) Awards is awarded to Nicholas Leach Current level and rate of warming determine emissions budgets under ambitious mitigation
The 2019 Arne Richter Awards for Outstanding Early Career Scientists is awarded to Amanda C. Maycock for significant and original contributions to the understanding of the influence of stratospheric processes on climate at temporal scales from seasons to centuries.
The anticipation is rising, the offices smell of gingerbread and cookies, papers get written to be done just in time for Santa and his elves. Everyone is happily stressed these days working on the perfect Christmas presents, but then… aah, what to present at next year’s EGU? Which session to attend? This is a friendly reminder of the abstract submission deadline at 15th January. Read up on how to submit an abstract and check the complete program. To make things …
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 …
This month the EGU announced the results of the autumn 2019 elections, which included selecting the Union’s next President, General Secretary and Division Presidents. We also opened two calls for geoscience teachers: one to attend a GIFT workshop in March that will be held in conjunction with the 36th International Geological Congress in Delhi, India, and a second for university-level geoscience teachers to attend a teaching focus group meeting associated with the 2020 General Assembly.
Please remember that the deadline for abstracts for the General Assembly is 15 January 2020 at 13:00 CET. Before then, consider renewing your EGU membership to be part of Europe’s largest geosciences union. EGU members are eligible to submit an abstract to the General Assembly and enjoy substantially reduced meeting registration rates, among other benefits.
Applications are now open for the EGU General Assembly Mentoring Programme (deadline: 31 January 2020).
