Global warming and climate change are realities clearly established by scientists. Unfortunately, these facts are disputed by some in the media and on the internet via social networks in particular, without any scientific basis.It’s essential to implement action in order to raise awareness about this problem among young people. Thus, it is necessary that they understand that global warming is mainly due to greenhouse gas emissions related to human activities. One of the main sources of greenhouse gas emissions is transportation: travel to school, work, to access different services or hobbies, etc. Thus, the first part of this Erasmus+ project will consist of an analysis of the problem. We'll do some statistics of the temperature and rainfall in the different countries over many years. We'll do experiments about greenhouse effect and measure greenhouse gas emissions. We'll also make the pupils understand how to compensate these emissions.
