About 2 billion years ago, the oceans were green, the land red and rocky, and only 1 percent of Earth’s atmosphere was oxygen. How did the planet become what it is today? UNC geochemist Xiao-Ming Liu collects samples of soil, rocks, and water from places like Hawaii to find the answer.
While the United States and China take up roughly the same amount of land mass, China’s population is over four times that of the U.S. — and more people means more change in vegetation growth. How do these factors connect to climate change? Conghe Song explores this relationship, pursuing a project that has led to his return to his birthplace: rural China.
Allison Duprey and Andrew Zachman experience new opportunities through hands-on fieldwork — right here, on UNC’s campus.
Erika Wise is an associate professor of geography in the UNC College of Arts & Sciences, head of the Climate & Tree Ring Environmental Science research group, and an affiliate faculty member within the Institute for the Environment. Her research focuses on tree ring patterns and deciphering what they tell us about climate change.
Margaret Jones is a graduate student studying geological sciences in the UNC College of Arts and Sciences. Her thesis work involves developing a shoreline-change model to determine coastal responses to climate change.
