This essay addresses the positions supporting and opposing the phenomenon of global warming, stating that it is a real scientifically supported concern, which requires interventions. Global warming has been a controversial topic for many years now, with some believing that it is a real and pressing concern, while others claim that it is nothing more than a hoax. The scientific consensus is that global warming is a real and pressing concern, and that human activity is the main driver of it. However, there are still some who deny this consensus, claiming that natural causes such as solar activity and the medieval warm period are responsible for the recent rise in temperatures. Additionally, they claim that carbon dioxide, which is a greenhouse gas, is not responsible for global warming. Finally, they argue that the costs of mitigating and adapting to global warming outweigh the benefits.
