  • Photo: Sea surface temperature data set Study models the past to understand the future of strengthening El Niño Nov. 26, 2014 El Niño is not a contemporary phenomenon; it’s long been the Earth’s dominant source of year-to-year climate fluctuation. But as the climate warms and the feedbacks that drive the cycle change, researchers want to know how El Niño will respond. A team of researchers led by the University of Wisconsin’s Zhengyu Liu will publish the latest findings in this quest Nov. 27 in Nature.
  • Crops play a major role in the annual CO2 cycle increase Nov. 19, 2014 In a study published Wednesday, Nov. 19, in Nature, scientists at Boston University, the University of New Hampshire, the University of Michigan, the University of Minnesota, the University of Wisconsin-Madison and McGill University show that a steep rise in the productivity of crops grown for food accounts for as much as 25 percent of the increase in this carbon dioxide (CO2) seasonality.
  • They know the drill: UW leads the league in boring through ice sheets Oct. 30, 2014 Hollow coring drills designed and managed by UW-Madison’s Ice Drilling Design and Operations (IDDO) program are used to extract ice cores that can analyze the past atmosphere. Shaun Marcott, an assistant professor of geoscience at UW-Madison, was the first author of a paper published today in the journal Nature documenting carbon dioxide in the atmosphere between 23,000 and 9,000 years ago, based on data from an 11,000-foot hole in Antarctica.
  • Photo: Downtown Madison isthmus When the isthmus is an island: Madison’s hottest, and coldest, spots Oct. 21, 2014 In a new study published this month in the Journal of Applied Meteorology and Climatology, University of Wisconsin-Madison researchers highlight the urban heat island effect in Madison: The city’s concentrated asphalt, brick and concrete lead to higher temperatures than its nonurban surroundings.
  • Photo: Birds gather at bird feeder Climate change alters cast of winter birds Oct. 16, 2014 Over the past two decades, the resident communities of birds that attend eastern North America’s backyard bird feeders in winter have quietly been remade, most likely as a result of a warming climate. Writing this week in the journal Global Change Biology, University of Wisconsin-Madison wildlife biologists Benjamin Zuckerberg and Karine Princé document that once rare wintering bird species are now commonplace in the American Northeast.
  • Actions on climate change bring better health, study says Sept. 22, 2014 The number of extremely hot days in Eastern and Midwestern U.S. cities is projected to triple by mid-century, according to a new study led by University of Wisconsin-Madison researchers and published today in the Journal of the American Medical Association.
  • Photo: Brandon Barton Dwindling wind may tip predator-prey balance Sept. 19, 2014 Bent and tossed by the wind, a field of soybean plants presents a challenge for an Asian lady beetle on the hunt for aphids. But what if the air - and the soybeans - were still?
  • Helping communities prepare for climate change Aug. 21, 2014 Over the last several decades, Wisconsin has seen an increase in extreme weather and variability, and these conditions are likely to become more common in the years ahead. Scientists in the Nelson Institute Center for Climatic Research (CCR) project a sharp rise in average annual temperatures in coming decades – somewhere between 4 and 9 degrees Fahrenheit – spawning more frequent and intense storms, droughts and heat waves. These trends will challenge cities throughout the state.
  • Photo: Volker Radeloff No one-size-fits-all approach in a changing climate, changing land Aug. 18, 2014 As climate change alters habitats for birds and bees and everything in between, so too does the way humans decide to use land. Researchers at the University of Wisconsin-Madison and Aarhus University in Denmark have, for the first time, found a way to determine the potential combined impacts of both climate and land-use change on plants, animals and ecosystems across the country.
  • Antarctic ice sheet Climate conundrum: Conflicting indicators on what preceded human-driven warming Aug. 11, 2014 When the Intergovernmental Panel on Climate Change recently requested a figure for its annual report, to show global temperature trends over the last 10,000 years, the University of Wisconsin-Madison’s Zhengyu Liu knew that was going to be a problem. Writing in the journal Proceedings of the National Academy of Science today, Liu and colleagues describe a consistent global warming trend over the course of the Holocene, our current geological epoch, counter to a study published last year that described a period of global cooling before human influence.
  • Fossil soils Buried fossil soils found to be awash in carbon May 25, 2014 Soils that formed on the Earth’s surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet’s carbon cycle.
  • Research by UW shapes national climate report May 8, 2014 University of Wisconsin-Madison researchers, including many affiliated with the Nelson Institute, contributed to the third U.S. National Climate Assessment released by the White House on May 6.
  • Dan Vimont Initiative reaches out to state residents on climate change Dec. 12, 2013 As climate change impacts the diversity and distribution of species statewide, University of Wisconsin-Madison researchers, wildlife officials and others are collaborating to inform the public about these changes and ways to adapt.
  • Photo: planktonic foraminifera New techniques sharpen climate record found in fossil shells Oct. 18, 2013 Locked inside the fossil shells of a marine plankton are the secrets of past climate.
  • Report examines sensitivity of coastal areas to climate change Aug. 7, 2013 A new study of the nation’s coastal areas and surrounding communities examines the potential risks that these areas would face from a changing climate.
  • Photo: Jen Kaiser boarding plane Delving into a climate puzzle with the push of a button July 10, 2013 As University of Wisconsin-Madison graduate student Jen Kaiser settles into life in Smyrna, Tenn., this summer, her days develop a rhythm. She wakes up early, checks the weather forecast, and heads to Sewart Air Force Base.
  • Understanding the past and predicting the future by looking across space and time May 23, 2013 Studying complex systems like ecosystems can get messy, especially when trying to predict how they interact with other big unknowns like climate change.
  • Decline in snow cover spells trouble for many plants, animals May 6, 2013 For plants and animals forced to tough out harsh winter weather, the coverlet of snow that blankets the north country is a refuge, a stable beneath-the-snow habitat that gives essential respite from biting winds and subzero temperatures.
  • Filmmaker, glaciologist, artist to receive honorary degrees May 17 April 23, 2013 Honorary degrees will be bestowed on three individuals considered to be pioneers in their fields at UW–Madison commencement in May. One is a groundbreaking documentary filmmaker, another is a trailblazing glaciologist, and the third is a world-renowned glass artist.
  • Thin clouds drove Greenland’s record-breaking 2012 ice melt April 3, 2013 If the sheet of ice covering Greenland were to melt in its entirety tomorrow, global sea levels would rise by 24 feet.
