A new estimate using sheet modeling finds that Greenland’s rate of ice loss this century could outpace that of any century over the past 12,000 years, when the last Ice Age ended.
Scientists used reconstructions of ancient climate to drive the…

Cosmic Diamonds Formed During Gigantic Planetary Collisions
It is estimated that over 10 million asteroids are circling the Earth in the asteroid belt. They are relics from the early days of our solar system, when our planets formed out of a large cloud of gas and dust rotating around the sun.
When…

The Testimony of Trees: How Volcanic Eruptions Shaped 2000 Years of World History
Researchers have shown that over the past two thousand years, volcanoes have played a larger role in natural temperature variability than previously thought, and their climatic effects may have contributed to past societal and economic…

Geoscientists Discovers Causes of Sudden Volcanic Eruptions
Tiny crystals, ten thousand times thinner than a human hair, can cause explosive volcanic eruptions.
This surprising connection has recently been discovered by a German-British research team led by Dr. Danilo Di Genova from the Bavarian Research…

Remnants Ancient Asteroid Shed New Light on the Early Solar System
Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system.
About 4.5 Ga (giga-anum, or billion years ago), as a large disc of dust and ice collapsed around our newly formed star, planets and smaller…

Sea Ice Triggered the Little Ice Age
A new study finds a trigger for the Little Ice Age that cooled Europe from the 1300s through mid-1800s, and supports surprising model results suggesting that under the right conditions sudden climate changes can occur spontaneously, without…

Venus’ Ancient Layered, Folded Rocks Point to Volcanic Origin
An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic planet’s geological…

Undersea Earthquakes Shake up Climate Science
Despite climate change being most obvious to people as unseasonably warm winter days or melting glaciers, as much as 95 percent of the extra heat trapped on Earth by greenhouse gases is held in the world’s oceans.
For that reason, monitoring the…

Dust May Have Controlled Ancient Human Civilization
When early humans began to travel out of Africa and spread into Eurasia over a hundred thousand years ago, a fertile region around the eastern Mediterranean Sea called the Levant served as a critical gateway between northern Africa and Eurasia.
A…

Rebirth of a Volcano
Volcanoes are born and die – and then grow again on their own remains. The decay of a volcano in particular is often accompanied by catastrophic consequences, as was the most recent case for Anak Krakatau in 2018.
The flank of the volcano had…
