Date of an anomalous cooling event most likely triggered by a cosmic impact

At the end of the Pleistocene period, approximately 12,800 years ago­ — give or take a few centuries — a cosmic impact triggered an abrupt cooling episode that earth scientists refer to as the Younger Dryas.

Volcanic rocks resembling Roman concrete explain record uplift in Italian caldera

The discovery of a fiber-reinforced, concrete-like rock formed in the depths of a dormant supervolcano could help explain the unusual ground swelling that led to the evacuation of an Italian port city and inspire durable building materials in the future, Stanford scientists say.

Did a volcanic cataclysm 40,000 years ago trigger the final demise of the Neanderthals?

The Campanian Ignimbrite (CI) eruption in Italy 40,000 years ago was one of the largest volcanic cataclysms in Europe and injected a significant amount of sulfur-dioxide (SO2) into the stratosphere.

New, tighter timeline confirms ancient volcanism aligned with dinosaurs’ extinction

A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago spewed enormous amounts of climate-altering gases into the atmosphere immediately before and during the extinction event that claimed Earth’s non-avian dinosaurs, according to new research from Princeton University.

Study Hints that Ancient Earth Made Its Own Water—Geologically

A new study is helping to answer a longstanding question that has recently moved to the forefront of earth science: Did our planet make its own water through geologic processes, or did water come to us via icy comets from the far reaches of the solar system?

Past global warming similar to today’s

The rate at which carbon emissions warmed Earth’s climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to the atmosphere, University of Utah researchers and their colleagues found.

Secrets of Dinosaur Ecology discovered in fragile amber

The research conducted by Ryan McKellar’s sounds like it could of come straight out of Jurassic Park: he studies pieces of amber found buried with dinosaur skeletons. However, instead of re-creating dinosaurs, McKellar uses the tiny pieces of fossilised tree resin to study a world where the extinct animals thrived.
