During another time in which Earth warmed rapidly in conjunction with a spike in atmospheric carbon similar to our modern climate, seawater temperature and chemical changes decimated an important piece of the food web in the tropical Pacific Ocean.
Researchers at the Wisconsin Geological and Natural History Survey are spending a little less time on the ground and more time in the air — looking at the ground. What they're finding could help improve water quality.
A new study shows that underground reservoirs currently have capacity to store enough atmospheric carbon dioxide to limit planetary warming to under two degrees Celsius (35.6 degrees Fahrenheit) relative to pre-Industrial temperatures by the year 2100.
Stephen Meyers calls his last Geosci 100 lecture of the semester “Living in an Uncertain World.” This year, he and his team have created a multimedia production that features a Twitter conversation with Dwayne "The Rock" Johnson about his favorite rock, a special video message from Chancellor Blank and a musical performance from local band Mr. Chair.
New research on dunes in China describes how even neighboring dunes can long remain in different and seemingly conflicting states — confounding the assessment of stabilization efforts and masking the effects of climate change.
New UW–Madison research shows how bacteria can degrade solid bedrock, jump-starting a long process of alteration that creates the mineral portion of soil.
Lisa Kamal says she auditioned to be the student speaker for winter commencement because she believes she has something to say about keeping an open mind and adapting to one’s circumstances.
“If we can analyze melt inclusions, that will provide the first data on rock chemistry for the Earth’s ‘Dark Ages,’ the first 500 million years of earth history,” John Valley says. “This is a critical time that we know almost nothing about.”
Geologist Esther Stewart makes a living poking around in the geologic basement beneath Wisconsin, which provides many clues to the land's history.
A dinosaur found in Wyoming is helping UW–Madison researchers rewrite the family history of dinosaurs and modern birds.
A study provides a direct link between changes in Cahokia’s population size as measured through a unique fecal record and environmental data showing evidence of drought and flood.
UW-Madison researchers are more than one year into a project sponsored by Wisconsin Sea Grant aimed at a better understanding how the bluffs erode, and what triggers their collapse.
It’s a major task to understand a Laguna del Maule mountaintop region that has erupted 50 times over the past 20,000 years. But the starting point of a UW–Madison study is simple: It’s the ring that standing water leaves on a bathtub.
