The NCCR Climate strongly promotes the education of young researchers. To encourage exchanges between Ph.D. students, Post-Docs and leading climate researchers, we have created the "International NCCR Climate Summer School", which has become a highly appreciated opportunity to share scientific ideas and create cross-disciplinary links. The Summer School traditionally takes place in the scenic Alpine setting of Grindelwald, Switzerland. It consists of keynote lectures, workshops, poster sessions and excursions to research sites. The Summer School is open to young researchers worldwide. Participation is very competitive and limited to a maximum of 70.
