New Study Reveals Earth's Temperature Fluctuations Over 485 Million Years

Researchers have created the most detailed reconstruction of global temperatures, highlighting the strong link between CO₂ levels and climate shifts.

Published in Science, the study combines fossil data and climate models to chart Earth's temperature history.
The research shows that Earth's temperatures have varied more drastically than previously thought, with significant periods of extreme heat.
Carbon dioxide levels are identified as the primary driver of these historical temperature changes.
The findings underscore the unprecedented rate of current human-caused warming compared to past natural shifts.
This comprehensive temperature curve is expected to aid future climate models and deepen understanding of Earth's climate sensitivity.
