prehistoric climate
Dinosaur-era atmosphere conditions
The climate conditions that existed on Earth before written human records, spanning billions of years and reconstructed through geological evidence like ice cores, tree rings, fossils, and sediment layers.
Prehistoric climate varied dramatically—from global ice ages to periods when tropical forests reached polar regions.
Prehistoric climate data helps scientists model future warming scenarios.
