NASA Satellites On-Hand As Dorian Becomes a Category 3 Hurricane
As Hurricane Dorian was upgraded to a Category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale, NASA’s fleet of satellites were gathering data during the day to assist weather forecasters and scientists.
Scientists Discover Evidence for past High-Level Sea Rise at Current Atmospheric Carbon Dioxide Levels
An international team of scientists, studying evidence preserved in speleothems in a coastal cave, illustrate that more than three million years ago – a time in which the Earth was two to three degrees Celsius warmer than the pre-industrial era – sea level was as much as 16 meters higher than the present day.
Oxygen Depletion in Ancient Oceans Caused Major Mass Extinction
Late in the prehistoric Silurian Period, around 420 million years ago, a devastating mass extinction event wiped 23 percent of all marine animals from the face of the planet.
For years, scientists struggled to connect a mechanism to this mass extinction, one of the 10 most dramatic ever recorded in Earth’s history. Now, researchers from Florida State University have confirmed that this event, referred to by scientists as the Lau/Kozlowskii extinction, was triggered by an all-too-familiar culprit: rapid and widespread depletion of oxygen in the global oceans.
Their study, published today in the journal Geology, resolves a longstanding paleoclimate mystery, and raises urgent concerns about the ruinous fate that could befall our modern oceans if well-established trends of deoxygenation persist and accelerate.
Unlike other famous mass extinctions that can be tidily linked to discrete, apocalyptic calamities like meteor impacts or volcanic eruptions, there was no known, spectacularly destructive event responsible for the Lau/Kozlowskii extinction.

Researchers Determine Pollen Abundance and Diversity in Five Major Pollinator-Dependent Crops
A new study provides valuable insights into pollen abundance and diversity available to honeybee colonies employed in five major pollinator-dependent crops in Oregon and California, including California’s massive almond industry.
