Hidden Climate Thermostats Could Accelerate or Alter the Timing of the Next Ice Age
Overview: A Two-Thermostat View of Earth’s Climate Scientists have long explored how Earth naturally regulates its climate on geological timescales. The classic model centers on the silicate weathering feedback: when the planet warms and rain increases, CO2 is drawn down through chemical reactions with silicate rocks, ultimately storing carbon in oceans and sediments. This slow…

Hidden Thermostats in Earth’s Climate: Could an Organic-Carbon Supercharger Accelerate the Next Ice Age?
Two Climatic Thermostats Regulating Earth’s Balance Earth’s climate has long been understood to be moderated by natural feedbacks that act like thermostats. The well-known silicate weathering feedback is a slow, geological process: rain erodes silicate rocks, CO2 is drawn down to form carbonates in the ocean, and atmospheric CO2 levels drift back toward a balance…
