Climate change has solid scientific basis and especially now it is fundamental to look back at facts. We are a group of early career scientists working on climate change, wanting to take the opportunity to contribute to the discussion. The workshop explores in an easily accessible way the scientific background knowledge on the topic. We will focus on the interpretation of evidences of temperature increase and future climate predictions. The workshop starts with an introduction to key concepts, followed by interactive experiments and discussion in small groups, and time for questions and answers is reserved. Because climate change is a matter of understanding and not believing.
