Earth’s latest ice age may have been caused by changes deep inside the planet. Based on evidence from the Pacific Ocean, including the position of the Hawaiian Islands, Rice University geophysicists have determined Earth shifted relative to its spin axis within the past 12 million years, which caused Greenland to move far enough toward the

Currently, half of the world’s measured precipitation that falls in a year falls in just 12 days, according to a new analysis of data collected at weather stations across the globe. By century’s end, climate models project that this lopsided distribution of rain and snow is likely to become even more skewed, with half of

Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to a first-of-its-kind seismic study that spans the Mariana Trench. The observations from the deepest ocean trench in the world have important implications for the global water cycle, according to researchers in

The Atacama Desert, the driest and oldest desert on Earth, located in northern Chile, hides a hyper-arid core in which no rain has been recorded during the past 500 years. But this situation has changed in the last three years. For the first time, rainfall has been documented in the hyper-arid core of the Atacama,

A survey of ice in Greenland has uncovered evidence suggesting a kilometer-wide iron asteroid slammed into that island, perhaps as recently as 12,000 years ago during the end of the Pleistocene. The resulting 19-mile-wide impact crater has remained hidden under a half-mile-thick ice sheet until now. It recently was exposed by an ultra-wideband chirp radar

Where did Earth’s global ocean come from? A team of Arizona State University geoscientists led by Peter Buseck, Regents’ Professor in ASU’s School of Earth and Space Exploration (SESE) and School of Molecular Sciences, has found an answer in a previously neglected source. The team has also discovered that our planet contains considerably more hydrogen,

The world’s last wilderness areas are rapidly disappearing, with explicit international conservation targets critically needed, according to University of Queensland-led research. The international team recently mapped intact ocean ecosystems, complementing a 2016 project charting remaining terrestrial wilderness. Professor James Watson, from UQ’s School of Earth and Environmental Sciences, said the two studies provided the first

Sixty-six million years ago, an asteroid the size of a small city smashed into the earth. This impact, the one that would lead to the end of the dinosaurs, left a scar several miles underground and more than 115 miles wide. Chicxulub, which lies underneath the Yucatán Peninsula of Mexico, is the best-preserved large impact

A new study by researchers at The Australian National University (ANU) could help us understand how our planet was formed. Associate Professor Hrvoje Tkalčić and PhD Scholar Than-Son Phạm are confident they now have direct proof the earth’s inner core is solid. They came up with a way to detect shear waves, or “J waves”

A group of researchers have discovered the retreat of an ancient ice sheet from the western coast of Canada occurred earlier than previously thought. Dr. Christopher Darvill from The University of Manchester’s Department of Geography is the lead author on a new paper published in Geophysical Research Letters. Darvill and his co-authors studied the Cordilleran
