Climate and weather extremes seminar

Research on climate and weather extremes is a fundamental part of research at PIK and is carried out in different forms in every department. Extreme climate and weather events pose a serious threat to both the environment and society. Every year, heat waves, wild fires, hurricanes, extreme rainfall events, wind storms and droughts affect people in many parts of the world, causing economic damages and endangering human lives. 2022 saw extreme heat in Western Europe, China and Pakistan while Pakistan was hit by extreme monsoon rains and Himalayan glaciers melting which resulted in a country wide flood killing more than 1700 people and causing $15 billion of damage. While extremes would happen also in a stable climate, anthropogenic induced climate change has already increased the severity and frequency of certain specific extreme events, above all, extreme heat waves in the mid-latitudes and subtropical regions.

The scope of this cross-departmental quasi-monthly meeting is to bring together early career and senior scientists that work on extremes research at PIK, and outside PIK.

This seminar covers a broad list of topics, from atmosphere dynamics and the meteorological patterns which cause extreme weather events, to impacts of such extremes on agriculture, infrastructures, economy and society, to newly developed methods to analyze rare and impactful extreme events. The aim of this seminar is not only to reach a PIK wide audience but also to facilitate learning from one another and fostercollaboration across different groups and research departments. To achieve this goal, when feasible, we intend to organise pairs of 20’ presentations thematically linked but presented by researchers from different research department.

The seminar is held online and in presence about one per month. Everyone is invited to attend and the program for each meeting is sent around a week in advance to If you would like to present your research or would like to propose an external presenter, please get in touch with Giorgia Di Capua ( or Norbert Marwan (
