Climate change could strengthen African Easterly Waves, which could in turn have consequences for rainfall in the Sahel region of northern Africa, the formation of Atlantic hurricanes, and dust transport across the Atlantic Ocean.
Why did the ancestors of clams and oysters flourish after one of the worst mass extinctions in Earth’s history while another class of shelled creatures, the brachiopods, sharply decline? A new study that uses fossils to calculate the food intake of both groups seeks to answer that question.
Using radar measurements gathered
by NASA’s Cassini spacecraft, Stanford geophysicist Howard Zebker and his team
have concluded that the surface of Ligeia Mare, Titan’s second largest sea, has
a mirror-like smoothness, possibly due to a lack of winds. As the only other
solar system body with an Earth-like weather system, Titan could serve as a
model for studying our own planet’s early history.
An increase of more than two degrees Celsius in average global temperature is likely to cause yields of wheat, rice and maize to fall throughout the 21st century. Early adaptation could increase projected yields by up to 15 percent.
Kate Maher and Page Chamberlain have modeled how the topography and rock composition of a landscape affects the process by which carbon dioxide is transferred to oceans and eventually buried in Earth’s interior.
Stanford geophysicist Rosemary Knight is employing novel surface
technology to study intrusion of saltwater into freshwater aquifers along the
Monterey and Santa Cruz county coasts. She is available for media interviews on
Thursday, March 13 from
10am to 4pm Pacific Time, and also on March 17 and 18.
This course will run from April 1 to June 10 and encompass the fields of rock mechanics, structural geology, earthquake seismology and petroleum engineering to address a wide range of geomechanical problems that arise during the exploitation of oil and gas reservoirs.
From nuclear waste to strategic minerals for renewable energy, Rod Ewing wants to inject more science into long-term solutions. The recipient of a PhD in geology from Stanford in 1974, Ewing returns to The Farm with joint appointments in the School of Earth Sciences and the Center for International Security and Cooperation.
A review of more than 200 earlier studies confirms that U.S. emissions of methane are considerably higher than official estimates. Leaks from the nation's natural gas system are an important part of the problem.
