As we try to predict what will happen under increasing anthropogenic climate change, climate models can only get us so far. Another key is understanding past changes in the Earth’s climate. To do this, palaeoclimatologists turn to natural archives (e.g., sediment cores and speleothems) and extract records of past variability using their properties, such as chemical or physical composition.

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 anthro ...[Read More]

About

Welcome to the blog of the Climate: Past, Present and Future (CL) Division of the European Geosciences Union (EGU). The CL division covers all aspects of the ocean-climate-atmospheric systems, encompassing multiple, overlapping and complementary disciplines. We focus on the reconstruction of past climatic changes, the state of the current climate, and model predictions of future climate scenarios.

Through this blog, we aim to share a wide range of topics in climate science, not only with fellow scientists, but also with anyone interested in learning more about the climate system and its changes. This blog is run with great enthusiasm by our Editors-in-Chief. Everybody is warmly invited to contribute to the blog and submit posts to either Bianca Biess, Ceren Moral, or Valeria Mascolo.

For any other information, please contact the CL ECS Representative.
