Miocene CO₂ spikes linked to ENSO amplification reveal climate system sensitivity to greenhouse gases

The Miocene era offers a historical precedent for understanding how high CO₂ levels can influence climate oscillations. Similar to today, the Miocene saw significant climate shifts that can be compared to current anthropogenic climate change, offering lessons on long-term climate system behavior.
The study of Miocene CO₂ and ENSO dynamics reveals a climate system highly sensitive to greenhouse gas concentrations, with implications for modern climate modeling and policy.
By integrating Indigenous knowledge and cross-cultural perspectives, we can develop more robust and inclusive climate strategies. Historical parallels between the Miocene and current anthropogenic emissions highlight the urgency of reducing CO₂ to avoid destabilizing climate systems. Future modeling must account for these paleoclimatic insights to improve predictions and inform adaptive measures, particularly for marginalized communities most at risk from climate extremes.
