A new study in #Geology uncovers evidence that massive undersea volcanic eruptions—marine large igneous provinces—may have been a major, underrecognized driver of extinction throughout Earth’s history.

What can 3 million year old air bubbles tell us about the future? Two groundbreaking studies of ancient Antarctic blue ice reveal how prehistoric climate feedbacks shaped our world—and how quickly we are now spinning those processes into reverse.

New research from Antarctic "blue ice" has extended our direct record of Earth’s atmosphere back 3 million years, providing a window into the Pliocene-Pleistocene Transition.

Mantle plume–driven uplift accelerated erosion and carbonate weathering, temporarily creating a powerful carbon sink that may have outpaced volcanic degassing from the CO₂-poor Emeishan basalts.

A new perspective on deep Earth–climate interactions!🤔

The Isotope Archive: How Paleoclimate Science is Narrowing the Gap in Climate Projections By analysing high-resolution proxies and deep-time isotopes, researchers are uncovering the Earth’s true response to rising greenhouse gas levels.

How do we predict the climate of 2030, 2050 or 2100? We have to interrogate the past. Modern weather records only go back about 150 years. To understand where our planet is heading, we need a longer memory.
