Michael Pavolonis thinks of himself as a volcano guy.
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.
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.
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.
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.
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.
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?
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.
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.
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.
It’s a rainbow. It’s a sun dog. No, it’s a fire rainbow, which isn’t actually a rainbow at all.
The latitude at which tropical cyclones reach their greatest intensity is gradually shifting from the tropics toward the poles at rates of about 33 to 39 miles per decade, according to a study published today (May 14, 2014) in the journal Nature.
Michael Mann, creator of the well-known “hockey stick” graph depicting a sharp recent increase in our planet’s temperature, will deliver the fifth annual Len Robock Lecture on Thursday, April 17 at the University of Wisconsin–Madison.
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.
Newly created laser images of central Wisconsin show fields of dunes, most of which have never been seen before, that were blowing in the wind as recently as about 11,000 years ago.
Locked inside the fossil shells of a marine plankton are the secrets of past climate.
Louis Uccellini, head of the National Weather Service and a University of Wisconsin–Madison alumnus, will bring the service’s plan to build a “Weather-Ready Nation” to the UW–Madison campus Thursday evening.
