Scientists have solved a mystery of how the dinosaur-era greenhouse age ended. The cooling of the world has been traced to a ...

Sixty-six million years ago, Earth was a tropical greenhouse. Today, it's an ice-capped world. And an international team of experts led by the University of Southampton think they know why. Their new ...

Now that we have the experiment started, as Hannah discusses in her most recent post, we’re done sorting amphipods and have moved onto doing seawater chemistry. Every morning we test six water samples ...

Evidence from fossil shells suggests that falling seawater calcium helped lock away carbon dioxide and helped cool Earth after the dinosaurs.

Scientists have uncovered a surprising mechanism that may explain how Earth cooled dramatically after the age of dinosaurs.

Scientists discovered exceptionally preserved Ediacaran fossils in sandstone, revealing how soft-bodied organisms survived ...

A 66 million-year-old mystery behind how our planet transformed from a tropical greenhouse to the ice-capped world of today ...

Scientists trace Earth’s long cooling to falling ocean calcium, pulling CO₂ from the air and offering new insight into a greenhouse mystery.

New research links chemical changes in seawater to volcanic activity and changes. Sea salt hides a secret: tiny droplets of the seawater from which it came, preserving geologic history. Using ...

The Ediacara Biota are some of the strangest fossils ever found—soft-bodied organisms preserved in remarkable detail where ...
