## Executive Summary
A hidden ocean feedback kept Earth’s climate steady for 60 million years, challenging assumptions about climate volatility.

## Intelligence Brief
Coastal residents may fear abrupt climate shifts, but geological records reveal a long‑term steadiness in global temperatures. Scientists say a hidden ocean feedback, tied to sea‑level fluctuations and the cycling of a key nutrient, acted as a planetary thermostat for the past 60 million years.


Earth.com links sea‑level changes to this stability, while The Times of India points to the essential nutrient as a core component of the mechanism. The carbon that vanished from the atmosphere during this interval is now known to reside on the seafloor, according to CPG Click Oil and Gas, completing a cycle that regulated heat.


SciTechDaily reiterates the hidden thermostat concept, underscoring its long‑term role. Whether this natural buffering capacity can persist amid accelerating human emissions remains an open question for climate science.

## Verified Facts & Key Claims
### What natural process acted as Earth's climate thermostat?
Scientists identified a hidden ocean feedback involving sea‑level changes and the cycling of an essential nutrient that stabilized climate for 60 million years.

### Where is the carbon that disappeared from the atmosphere over the last 60 million years now located?
Research reported by CPG Click Oil and Gas says the carbon is buried on the seafloor, completing the regulatory cycle.

### What uncertainty remains about this climate‑regulating mechanism?
The coverage notes an open question whether the natural buffering capacity can continue under accelerating human emissions.
