Spotlights

Recent and projected increases in global temperatures, associated changes in regional moisture, and changes in the frequency of extreme climatic events have raised concerns about potential rapid...

Ken Kodama Delivers Bullard Lecture at AGU Conference

Ken Kodama’s reputation as a preeminent geophysicist and expert in paleomagnetism was affirmed earlier this month when he delivered the Edward Bullard Lecture at the annual meeting of the American...

Modeling Carbon

For years, scientists have known that human activities that burn fossil fuels like coal and oil are pumping carbon dioxide (CO2) into the atmosphere much faster than it is removed by natural...

Earthwise (click to watch)

Join us for the 2019 Foster Hewett Lecture Series! November 7th and 8th, 2019.

The Neoproterozoic, an interval extending from about 1000 to 540 millions years ago, saw profound changes that set the stage for our modern planet Earth. The time span saw the extreme global...

Subduction Top to Bottom 2 (ST2B-2) Taking Shape in GEOSPHERE

Subduction Top to Bottom 2 (ST2B-2) Taking Shape in GEOSPHERE
Subduction zones are where lithosphere is recycled into Earth’s mantle along ~55,000 km length of convergent plate margins (at...

Arctic Deep Sea Expedition 'Like Taking a Trip to the Moon'

Hydrothermal vents at the sea floor offer clues to the origins of life on earth, and beyond.
Before life on earth, what was there?
To be alive is to ponder that question and, perhaps, its natural...

Promoting Geospatial Learning

Armed with GPS-enabled iPads and infrared surface temperature thermometers, students in an urban high school in Pennsylvania fan out on their school property to take temperature readings of grass,...

Drought, fire, and forest composition

Recent and projected increases in global temperatures, associated changes in regional moisture, and changes in the frequency of extreme climatic events have raised concerns about potential rapid...

The Attraction of Sedimentary Rocks

Kenneth Kodama knows that rocks retain a faithful record of the magnetic field, a fact that has had a tremendous variety of applications, including the reconstruction of continental positions...

Modeling surface hydrology

River systems support industry, agriculture, and the infrastructure that helps drive modern society. The world’s regional climates are influenced by water, and local responses to climate change are...

A Sharper Image of Climate Change

The Earth’s climate has changed throughout history. Most of these changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. Yet,...

Tectonic Rates

Geologist David Anastasio, together with a team of Lehigh students, traveled last fall to northern Spain to examine rock formations as part of an effort to better understand the time-based variation...
