On 11 April 2017, the Swiss global change science community met for the 18th time on the annual Swiss Global Change Day. About 220 participants attended the event and 70 posters were exhibited. Distinguished researchers presented scientific highlights and the program provided enough time for discussions and networking. This went hand in hand with the key messages: Be a connector and a communicator. Also, ProClim followed that principles: For the first time there was a live reporting about the event on the Twitter channel of ProClim.
