Global warming is one of the most studied and debated phenomena of our era. But do we really understand its causes and dynamics? In this book, the author questions conventional theories about the greenhouse effect and proposes a new vision.Through a meticulous analysis, he shows that the absorption of ultraviolet radiation by atmospheric oxygen plays a much more decisive role in global warming than the action of greenhouse gases. This revealing theory is supported by various studies and data that challenge the prevailing paradigm.Far from claiming to have the absolute truth about this complex phenomenon, the author seeks to contribute to the scientific debate with a novel approach. His perspective invites the academic community to re-examine entrenched conceptions and continues the relentless human quest to understand the intricate natural processes that affect us all.
