Volcanoes Tied to Shifts in Earth’s Climate Over Millions of Years

April 22, 2016

A new study in the April 22 Edition of Science reveals that volcanic activity associated with plate-tectonic movement of continents may be responsible for climactic shifts from hot to cold over tens and hundreds of millions of years throughout much of Earth’s history.

The study, led by researchers at The University of Texas at Austin Jackson School of Geosciences, addresses why the Earth has fluctuated from periods when the planet was covered in ice to times when even the polar regions were ice-free.
