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

The unity of government which constitutes you one people is also now dear to you. It is justly so, for it is a main pillar in the edifice of your real independence, the support of your tranquility at home, your peace abroad; of your safety; of your prosperity; of that very liberty which you so highly prize. But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth.  George Washington - Farewell Address
