Wisconsin cave holds tantalizing clues to ancient climate changes, future shifts
Even in their dark isolation from the atmosphere above, caves can hold a rich archive of local climate conditions and how they’ve shifted over the eons. Formed over tens of thousands of years, speleothems — rock formations unique to caves better known as stalagmites and stalactites — hold secrets to the ancient environments from which they formed.
Research reveals new links behind climate change in Australia
A team of scientists, including those from Woods Hole Oceanographic Institution (WHOI), have combined stalagmites and climate model simulations to reveal links between monsoon rains and tropical cyclones in Australia.
Denniston receives NSF grant to study fire activity with stalagmites
The National Science Foundation (NSF) has awarded Cornell College W.H. Norton Professor of Geology Rhawn Denniston a $199,785 grant to study the use of stalagmites as records of prehistoric fire activity in the Australian tropics.
Denniston awarded NSF grant to study climate change
The National Science Foundation (NSF) has awarded a nearly half-million-dollar research grant to Cornell College Professor of Geology Rhawn Denniston and a team of researchers to study climate variability.
What Happens in Vegas, May Come From the Arctic?
Climate records from a cave in the southern Great Basin show that Nevada was even hotter and drier in the past than it is today, and that one 4,000-year period in particular may represent a true, “worst-case” scenario for the Southwest and the Colorado River Basin — and the millions of people who rely on its water supply.
