Earth’s Natural Thermostat Regulated Climate for 60 Million Years
Earth’s Natural Thermostat Regulated Climate for 60 Million Years
US · Published Jul 27, 2026
New research has uncovered a natural mechanism that has regulated Earth's climate over the past 60 million years.
Scientists found that changes in sea level, ocean oxygen levels, and phosphate availability have played a critical role in controlling atmospheric carbon dioxide levels.

Impact & Risks

The findings emphasize the importance of oceanic processes in maintaining Earth's climate stability. Disruptions to these natural mechanisms, such as those caused by human-induced climate change, could have significant consequences for global temperatures and carbon cycles. The study also highlights how past periods of high sea levels, such as during the Eocene epoch, weakened Earth's ability to sequester carbon, leading to warmer climates. Understanding these processes is crucial for predicting future climate scenarios and mitigating risks associated with rising atmospheric CO2 levels.
