Summary. The social perception of information is increasingly diverse and based on sources that in many cases are far removed from the traditional ones. New social mass media have opened the door to a universal 'rumorology,' which in the case of news related to science or objective knowledge often results in the transmission of misinformation and conspiracy theories. Global warming and climate change are a clear example of how scientific sources can be distorted and how, despite a scientific basis, the original source declared can be obscured. In the world of social networks, the communication of ideas and knowledge and of objective news are hopelessly confused. In society as a whole, science and news involving scientific knowledge are often reported unfiltered or without prior peer review, with only vague background knowledge. The social and global perception of climate change and the future of the planet have been shaped by social networks. Consequently, the theme of Earth Day 2011 is even more significant: 'A Billion Acts of Green,' or the universal socialization of a global necessity.
