Lacustrine ecosystems needed 10 million years to recover after end-permian mass extinction
Chinese Academy of Sciences

The end-Permian mass extinction (EPME), approximately 252 million years ago (Ma), caused a serious marine and terrestrial ecosystem crisis, and about 75% of terrestrial biological species disappeared. How long did it take for terrestrial ecosystems to recover?

For grounded forecast of volcanic unrest, spy from above
Cornell University

To better predict explosive, fiery volcanic activity, Cornell geologists have proposed a new classification system to discern the stages of a volcano’s unrest – as seen from smart, perceptive satellites.

Assessing Forests From Afar
University of Delaware

A new study led by the University of Delaware’s Pinki Mondal recommends that in addition to using large swaths of coarse satellite data to evaluate forests on a national scale, it is important for countries to prioritize areas such as national parks and wildlife refuges and use finer scale data in those protected areas to make sure that they are maintaining their health and are being reported on accurately.

Late Cretaceous dinosaur-dominated ecosystem
Geological Society of America (GSA)

A topic of considerable interest to paleontologists is how dinosaur-dominated ecosystems were structured, how dinosaurs and co-occurring animals were distributed across the landscape, how they interacted with one another, and how these systems compared to ecosystems today.

Greenland shed ice at unprecedented rate in 2019; Antarctica continues to lose mass
University of California, Irvine

Irvine, Calif., March 18, 2020 – During the exceptionally warm Arctic summer of 2019, Greenland lost 600 billion tons of ice, enough to raise global sea levels by 2.2 millimeters in two months. On the opposite pole, Antarctica continued to lose mass in the Amundsen Sea Embayment and Antarctic Peninsula but saw some relief in the form of increased snowfall in Queen Maud Land, in the eastern part of the continent.

Arrival delayed! Water, carbon and nitrogen were not immediately supplied to Earth
University of Cologne

Spearheaded by earth scientists of the University of Cologne, an international team of geologists has found evidence that a large proportion of the elements that are important for the formation of oceans and life, such as water, carbon and nitrogen, were delivered to Earth very late in its history.
