Climate change has been one of the hottest scientific and economic issues debated over the last decade. From Rome's Climate Conferences to the recent 2007 Nobel Peace Prize assigned to the IPCC (Intergovernemental Panel on Climate Change) and to Al Gore for their "commitment in the pursuit and dissemination of an improved knowledge of climate change", there are multiple occasions in which the public has to deal with a subject that is not always totally clear. Considering the high level of uncertainty on the causes of the problem, and in particular of the forecast of its effects, acknowledged by scientists all over the world, providing clear, fair and ethically correct information is essential. This was the background to the Forum on Climate Change that was organised in cooperation between Collegio di Milano and Fondazione ENI Enrico Mattei, where some of the best students of Milan's seven universities discussed the issue with university professors and climate change experts. The article focuses on two points: the multidisciplinary approach - regarded as essential in all climate change analyses - and the importance of correct communication.
