Summary

Story summary

The study shows Earth's climate fluctuated between chaotic and calm states during Late Paleozoic (360–250 million years ago).
Zhijun Jin from Peking University led the study, identifying three tectonic phases and orbital cycles influence climate stability.
In the middle phase, reduced tectonic activity coincided with stable carbon dioxide and burial leading to coal formation.
Active tectonic periods increased volcanic carbon dioxide and climate variability.
The findings were published in Nature.
