Curtin University research has shed new light on when one of the largest mass extinction events on Earth occurred, which gives new meaning to what killed Triassic life and allowed the ecological expansion of dinosaurs in the Jurassic period.https://secureframe.doubleclick.net/container.html?ecs=20201117

In and around the tangled roots of the forest floor, fungi and bacteria grow with trees, exchanging nutrients for carbon in a vast, global marketplace. A new effort to map the most abundant of these symbiotic relationships—involving more than...
Dust is a key component of Earth's climate system. When it interacts with clouds, oceans and the sun's radiation, it has an overall impact on our planet's living systems, affecting everything from weather and rainfall to global warming.
There are...

A new radioactivity model of Earth's ancient rocks calls into question current models for the formation of Earth's continental crust, suggesting continents may have risen out of the sea much earlier than previously thought but were destroyed, leaving little...
Now Florida State University researchers have found that the extinction coincided with a sudden spike and subsequent drop in the ocean's oxygen content. Their findings were published in Nature Geoscience.
Two hundred fifty-two million years ago, much of life...
A program to reduce Earth's heat capture by injecting aerosols into the atmosphere from high-altitude aircraft is possible, but unreasonably costly with current technology, and would be unlikely to remain secret.
Those are the key findings of new research published...
How do mountains form? What forces are needed to carve out a basin? Why does the Earth tremble and quake?
Earth scientists pursue these fundamental questions to gain a better understanding of our planet's deep past and present workings. Their...
For years, scientists have pointed to warming permafrost in the Arctic tundra as a source for increased carbon in the atmosphere; as this soil warms, it releases greenhouse gases that have long been trapped in frozen ground.
New research from...
