UA Climate Scientists Put Predictions to the Test

A new study has found that climate-prediction models are good at predicting long-term climate patterns on a global scale but lose their edge when applied to time frames shorter than three decades and on sub-continental scales.

Climate-prediction models show skills in forecasting climate trends over time spans of greater than 30 years and at the geographical scale of continents, but they deteriorate when applied to shorter time frames and smaller geographical regions, a new study has found. (more…)

Late-Night Comedy Television Increases Political Discussion

Politics

ANN ARBOR, Mich.— The jokes by late-night comedy television hosts can be just as effective as regular political news in spurring discussion among viewers, a new University of Michigan study shows.

In addition, political candidates could help their campaigns with mentions by shows like “The Daily Show with Jon Stewart,” “Late Show with David Letterman” or “The Tonight Show with Jay Leno.” (more…)

EAST LANSING, Mich. — Reading a classic novel such as “Pride and Prejudice” can be entertaining, but, according to new research by a Michigan State University professor, it also can provide many other benefits beyond that.

Natalie Phillips, an MSU assistant professor of English, and her team placed study participants in an MRI machine and monitored their brain flow while reading the works of Jane Austen. (more…)

UD faculty member teaches sociology and statistics with technology

Victor Perez, an assistant professor in the University of Delaware’s Department of Sociology and Criminal Justice, has found multiple ways to reach students using diverse technological approaches. Perez makes his classroom presentations highly interactive by combining a tablet with an engaging PowerPoint presentation.

Using the Wacom Bamboo tablet and its accompanying app, Perez creates illustrations of statistical formulas and distributions in class. “Bamboo Dock is something that I’ll use pretty frequently in the statistics course, and it looks literally like a journal. What’s great about this is that you can write any statistical formula, and it’s what students will see directly on the screen,” Perez said. (more…)

CU-led Mountain Forest Study Shows Vulnerability to Climate Change

Environment

A new University of Colorado Boulder-led study that ties forest “greenness” in the western United States to fluctuating year-to-year snowpack indicates mid-elevation mountain ecosystems are most sensitive to rising temperatures and changes in precipitation and snowmelt.

Led by CU-Boulder researcher Ernesto Trujillo and Assistant Professor Noah Molotch, the study team used the data — including satellite images and ground measurements — to identify the threshold where mid-level forests sustained primarily by moisture change to higher-elevation forests sustained primarily by sunlight and temperature. Being able to identify this “tipping point” is important because it is in the mid-level forests — at altitudes from roughly 6,500 to 8,000 feet — where many people live and play in the West and which are associated with increasing wildfires, beetle outbreaks and increased tree mortality, said Molotch.
