How shifting ocean pathways and continental shapes may have changed Earth's ice age cycles
By
Silvia Pineda-Munoz PhD
Summary
The article explores how changes in ocean circulation pathways, driven by continental shifts, have triggered major climate changes in Earth's history. It specifically examines a mystery about why Earth's ice age cycles changed about a million years ago, and suggests that scientists may have found a clue in the Arctic Ocean related to ocean currents and continental configuration.

· 3 pulledYet some of the largest climate changes in Earth's history happened because the oceans found a new route to flow.
But from a climate perspective, the exact pathways that water can take matter enormously.
Open a new connection and the entire climate system can shift.
