Rocks from the Rio Grande continental rift have provided a rare snapshot of active geology deep inside Earth's crust, revealing new evidence for how continents remain stable over billions of years, according to a team of scientists.
Ocean color satellites reveal glacier algae, insights for climate models

The brownish-grey algae that darken the Greenland ice sheet in summer cause the ice to melt faster, but only recently have scientists measured these blooms in the field, and only at few sites. To measure algal blooms across large regions and understand their effects on melting over time, scientists are now turning to space.
Deep learning artificial intelligence keeps an eye on volcano movements

Penn State researchers have used artificial intelligence (AI) to clear up noise in RADAR satellite data that can can help detect ground movements at volcanoes in near real time.
Climate impacts could put major fishery, food security at risk in East Africa

Climate change could put a major fishery -- and the millions of people who depend on it -- at risk in one of the world's most vulnerable regions, according to researchers.
Ice melt projections may underestimate Antarctic contribution to sea level rise

Fluctuations in the weather can have a significant impact on melting Antarctic ice, and models that do not include this factor can underestimate the global impact of sea level rise, according to Penn State scientists.
Fossil carbon burned by asteroid impact contributed to dinosaur extinction

10/01/2020
An asteroid impact 66 million years ago may have released trillions of pounds of partially burned fossil carbon into Earth's upper atmosphere as a cloud of black soot, significantly contributing to the ensuing global darkness, cooling and mass extinction that wiped out the dinosaurs, according to an international team of scientists.
Fracking bill analysis reveals how states may influence each other's policies

Even though State governments routinely rely upon interest groups to help them as they craft legislation, researchers found that certain peer-leader states, like Pennsylvania and Colorado, have greater influence in shaping states' fracking policies, in a study led by Penn State Professor of Geography Jennifer Baka.
Generating renewable hydrogen fuel from the sea

The power of the sun, wind and sea may soon combine to produce clean-burning hydrogen fuel, according to a team of Penn State researchers.
Increasing stability decreases ocean productivity, reduces carbon burial

09/28/2020
As the globe warms, the atmosphere is becoming more unstable, but the oceans are becoming more stable, according to an international team of climate scientists, who say that the increase in stability is greater than predicted and a stable ocean will absorb less carbon and be less productive.
Simpler models may be better for determining some climate risk

09/24/2020
Typically, computer models of climate become more and more complex as researchers strive to capture more details of our Earth's system, but according to a team of Penn State researchers, to assess risks, less complex models, with their ability to better sample uncertainties, may be a better choice.
