It’s our school’s responsibility to prepare the new generation for the demands of the new environment, providing new knowledge and skills, so that they understand the climate change and act to mitigate it. The investigation of the issue demands cross-curricular approach with the support of many teaching subjects both of exact science and humanities, so that the students will have the opportunity to assess information, knowledge and opinions, in order to develop analytical, critical thinking and compositional skills in a cooperative environment. The goal is 1. the multi-dimensional development of the student and the realization of the necessity to take action him/herself as responsible global citizens, so that they help create a better climatic environment through actions and every-day habits 2. the motivation of the society through the diffusion and cooperation with carriers.
