A new study led by University of Arizona researchers may have solved two mysteries that have long puzzled paleo-climate experts: Where did the ice sheets that rang in the last ice age more than 100,000 years ago come from, and how could they grow so quickly?... Read more

Global warming and a progressively drier climate in many parts of the world are causing more dust storms. To predict how these storms are caused, researchers are looking into the past to understand where the dust came from, for how long, and over what distances it was transported. An international...

In May 1997, a large earthquake shook the Kermadec Islands region in the South Pacific Ocean. A little over 20 years later, in September 2018, a second big earthquake hit the same location, its waves of seismic energy emanating from the same region.... Read more

Towering artificial ice reservoirs called "ice stupas" have emerged since 2014 as an accessible means of storing irrigation water in dry, high-altitude mountain villages. Now, experiments with automated systems have demonstrated that construction of these giant ice cones, which top 30 meters (100 feet), can be accomplished with about one-tenth... Read more

As rising sea levels cause marshes to move inland in six mid-Atlantic states, the coastal zone will not continue to serve as a carbon sink but release more carbon into the atmosphere, a new modeling study led by researchers at Duke University finds.... Read more

Seawater lithium isotopes (δ7Li) record changes over Earth history, including a ~9‰ increase during the Cenozoic, which is interpreted as the reflection of either a change in continental silicate weathering rate or weathering feedback strength, associated with tectonic uplift. However, mechanisms controlling the dissolved δ7Li remain debated.... Read more

A pair of researchers at the University of Nebraska's School of Natural Resources and Department of Earth and Atmospheric Sciences has conducted a zone-by-zone study of weather in Central Asia to learn more about changing conditions under global warming. In their paper published in the journal Geophysical Research Letters, Qui... Read more

The Great Lakes in the Midwest U.S. comprise the largest unfrozen freshwater stores on Earth. But too much of a good thing can create problems. New research using the most advanced regional climate modeling systems finds that the baseline lake level for Lake Superior, Michigan-Huron and Erie are expected to... Read more
