Geosciences Ph.D. candidate Adam Hudson, of the University of Arizona, digs up shells for radiocarbon dating from a dried out lake in Oregon. The dating will help reconstruct periods of glaciation when water filled the lake.
Scientists study glacial moraines of the now dry area of Convict Lake in the Great Basin to find clues to climate change.
Ancient shifts in the Earth's thermal equator caused massive changes in temperature and precipitation. Scientists are trying to find out if this could happen again today. Click on the image to enlarge it.
Aaron Putnam, climate scientist at Columbia University, presented research on glacial melt in the Great Basin of the western U.S. during a period of climate change 16,000 years ago. This research can help us understand climate change today.
