Highlights
•
We present the first reconstruction of sea level change during the last 540 million years due to the waxing and waning of the Earth’s polar icecaps.
•
Long-term reconstructions of sea level fail to capture short-term, high-amplitude fluctuations—especially those driven by glacio-eustasy during icehouse periods.
•
The study uses a high-resolution Cenozoic climate model and long term Phanerozoic ice volumes to estimate orbital-scale sea level variability over the past 540 million years.
•
Greenhouse climates like the Jurassic and Cretaceous saw reduced or absent glacial sea level fluctuations, in contrast to short term changes >100 meters during the Paleozoic and Cenozoic.
•
Sea level estimates during greenhouse periods may have been overstated by stratigraphic methods, or result fro
