How tectonics and astronomical cycles shaped the Late Paleozoic climate

Anders Carlson, a UW–Madison geologist, surveys an outlet glacier in southwest Greenland. Carlson and colleagues from UW–Madison and Oregon State University have shown that melting ice from Greenland may have raised ocean levels less than expected during the most-recent prolonged warm spell on Earth. The surprising patterns of ice melt found by new research suggest that Greenland’s ice sheet may be more stable — and Antarctica’s less stable — than previously thought.

A graphic showing the convective heat cycle (red arrows) that drives plate tectonic motion (black arrows) on Earth. Heat flows toward subduction zones through the uppermost mantle layer, the asthenosphere. A computer model from Rice University finds that the asthenosphere can locally drag plates along with it rather than acting exclusively as a brake on plate movements as had been widely believed.

Crustal brines at an oceanic transform fault

Creative destruction: a thinner ocean plate sides under a continental plate, melting and recycling the ocean crust into the Earth’s interior and birthing volcanoes in this illustration of subduction, a consequence of modern plate tectonics. A new study reports evidence of a transition in multiple locations around the world, 3.8-3.6 billion years ago, from stable “protocrust” to pressures and processes that look a lot like modern subduction, suggesting a time when plates first got moving.

Early Earth was bombarded by meteors which played a crucial role in disrupting and recycling Earth’s first crust.

Early Earth’s first crust composition discovery rewrites geological timeline

Artistic view of Earth’s interior during mantle solidification in the first hundreds of millions of years of Earth’s history. Gravitational segregation of dense, iron-rich magma (in orange) likely formed a basal magma ocean atop the core, that can explain the present-day structure of the lower mantle.
