Unveiling the Alarming Parallels: Today's CO2 Levels Echo Those of 14 Million Years Ago

A comprehensive study spanning 66 million years reveals that the last time atmospheric carbon dioxide (CO2) consistently reached today's human-driven levels was 14 million years ago, highlighting the sensitivity of long-term climate to greenhouse gas emissions. The study, conducted by a consortium of over 80 researchers, emphasizes the potential cascading effects of CO2 on the climate over millennia. While the research does not provide specific temperature predictions for the future, it strengthens the understanding of the relationship between CO2 and temperature throughout Earth's history, emphasizing the need for urgent climate action.
