Division on Climate: Past, Present & Future

President: Kerstin Treydte (Emailcl@egu.eu)
Deputy President: Gabriele Messori (Email)
ECS Representative: Shalenys Bedoya Valestt (Emailecs-cl@egu.eu)

The Division on Climate: Past, Present & Future (CL) is one of the larger divisions of the European Geosciences Union. It pools from many disciplines and consequently has many co-organised sessions with other divisions at the EGU 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 modelling 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.

When a major climate event goes almost unnoticed: the elusive 8.2 ka signal in southern France stalagmites

Around 8,200 years ago, the climate of the Northern Hemisphere experienced an abrupt disturbance. In Greenland ice cores, the signal is unmistakable: a rapid drop in temperatures, followed by a gradual return to previous conditions. This episode, which lasted about 150 years, is known as the 8.2 ka event (“ka” meaning thousand years before 1950). It is often described as the most prominent climate perturbation of the Holocene (the last ~11,700 years). The widely accepted explanation involves a massive release …


When European pollution reshaped the Asian summer monsoon

The Asian summer monsoon is one of the most powerful climate phenomena on Earth. Each year, it brings life-giving rainfall to billions of people across South and East Asia. Its arrival determines harvests, water supply, food security, and economic stability. We often think of the monsoon as something driven locally: by the heating of the Indian subcontinent, by ocean temperatures, or by regional pollution. But what if part of its history was shaped thousands of kilometres away? In our recent …


Inside the Baltic Sea N2O Hunt: Tracing Sources using Isotopic tools

Nitrous oxide (N2O), commonly known as laughing gas, is one of the most important greenhouse gases, and its rise in the Anthropocene significantly contributes to global warming and depletion of stratospheric ozone. The marine environment, especially coastal and marginal seas, is an important (about 25%) contributor to the global atmospheric source of N2O. Nitrous oxide is primarily produced in marine systems by special microbes – the nitrifiers and the denitrifiers. In oxygenated waters, the nitrifiers produce N2O as a byproduct …


Studying societal climate impacts: why is it hard and what can we do about it

Due to the rapid rise in temperatures, it started raining on the snow and ice-covered roads, prompting the regional public transport operator to suspend all bus services. The rain also resulted in icing on the overhead lines of the main railway line coming into town. Rail traffic was also temporarily suspended. Before the adjacent highway could be salted, several tens of cars were involved in a chain-reaction crash. It took several hours before the highway could be reopened. With no …

Current issue of the EGU newsletter

 In our March issue, we are preparing for the annual General Assembly on the EGU blogs and with a special webinar to help all EGU26 attendees refresh their knowledge of the meeting we are all systems go here in EGU HQ! Also learn about what it's like to spend 25 years working with Interactive Open Access publishing, don't miss out on science for policy events at EGU26, and the EGU awards and medals are now open for nominations - the process is probably easier than you think!

All this and much more, in this month's Loupe!
