In a new study, researchers make the case that large-scale glaciation during parts of the Neoproterozoic era led to extensive erosion of Earth’s crust.

Ice Drove Past Indo-Pacific Climate Variance
Researchers used both terrestrial and marine proxy data to reconstruct the dramatic and dynamic climatic changes.
How Did We Get Here?
With a discovery made from fossils in the seabed, paleoceanographers and paleoclimatologists began tracing the delicate path between ancient eras and our future.
What Ancient Rivers on Mars Reveal About Its “Great Drying”
Dried-up rivers on Mars suggest that the planet was wet in the not-too-distant past.
Ancient River Discovery Confirms Mediterranean Nearly Dried Up in the Miocene
Sedimentary deposits reveal a Nile-sized river system flowing from what are today Turkey and Syria.
Topography and Microclimate Shape Tree Ring Growth
Wizened bristlecone pines in California reveal past climate trends, and new research shows how slight variations in landscape position drive different growth patterns in trees’ annual rings.
Ancient Fires and Indigenous Knowledge Inform Fire Policies
Global Paleofire Working Group 2: Diverse Knowledge Systems for Fire Policy and Biodiversity Conservation; Egham, United Kingdom, 4–9 September 2018
Scientists Discover Pristine Collection of Soft-Tissue Fossils
The fossils include jellyfish, box jellies, branched algae, and sponges, which are underrepresented in or missing from other deposits.
Varying Impact of Earthquake- and Monsoon-Induced Landslides
Using nearly 50 years of satellite data and records stretching back millennia, scientists determine the relative frequency—and the erosional power—of monsoon- and earthquake-induced landslides in Nepal.
