Abstract
The emergence of global catastrophic risks, such as the Covid-19 pandemic, highlights the need to popularize scientific knowledge, in order to disseminate the best practices for combating, preventing and mitigating ongoing environmental, social, economic, geopolitical and technological threats. From this perspective, this article seeks to validate the scientific knowledge publicly available through the online lecture platform TED Talks. The methodology applied was qualitative analysis through comparison between information from scientific databases, with a systematic review of the literature, and analysis of 32 video lectures. The results point to a convergence between the understanding published in scientific articles about global catastrophic risks and the knowledge popularized by the digital lecture platform analyzed.
