Researchers with the University of Wisconsin-Madison say a stalagmite from Cave of the Mounds in southern Wisconsin holds clues about the impact of abrupt, global climate changes during the last ice age. A team of UW-Madison scientists led by Cameron Batchelor removed a stalagmite about the length of a pinky finger and used chemical and physical analysis to detect telltale signs of sudden warming in the atmosphere. A paper on their research was published this month in the journal Nature Geoscience.
“This work really puts Wisconsin on the map in terms of showing that this region of the world is not immune to these abrupt climate change events,” Batchelor told Wisconsin Public Radio.
