Author Peter Brannen's new book "The Story of CO2 Is the Story of Everything" explores how carbon dioxide has influenced Earth's climate throughout the planet's 4-billion-year history. The work examines major climate shifts that occurred across geological time scales, including periods when Earth experienced complete freezing.
The book provides historical context for understanding current atmospheric carbon dioxide levels by examining how CO2 concentrations have fluctuated throughout Earth's deep past. Brannen's analysis spans billions of years of planetary evolution, documenting how carbon dioxide levels have driven major environmental changes throughout geological history.
