Malaria infection risk influenced by daily temperature variations

2/19/13

Identifying areas of malarial infection risk depends more on daily temperature variation than on the average monthly temperatures, according to a team of researchers, who believe that their results may also apply to environmentally temperature-dependent organisms other than the malaria parasite.

Researchers to investigate Everglades ecosystem, climate change

2/4/13

Water management in the Florida Everglades is the focus of a National Science Foundation grant awarded to Jose Fuentes, professor of meteorology.

The project will explore the hydrologic, ecologic and economic impacts of management strategies designed to increase the resilience of the Everglades ecosystem to climate variability, climate change and sea level rise. This research is part of a larger, ongoing project at Florida International University looking at coastal ecology and hydrology. The Penn State award is for five years at $300,514.

New methods help scientists shed light on ancient climates

7/3/12

Tree ring and oxygen isotope data from the U.S. Pacific Northwest do not provide the same information on past precipitation, but rather than causing a problem, the differing results are a good thing, according to a team of geologists. The researchers are trying to understand the larger spatial patterns and timing of drought in the arid and semiarid areas of the American West.

Tree rings may underestimate climate response to volcanic eruptions

2/6/12

Some climate cooling caused by past volcanic eruptions may not be evident in tree-ring reconstructions of temperature change, because large enough temperature drops lead to greatly shortened or even absent growing seasons, according to climate researchers who compared tree-ring temperature reconstructions with model simulations of past temperature changes.

Penn State scientists elected to American Geophysical Union

2/1/12

Michael Mann and David Pollard, both scientists in Penn State's College of Earth and Mineral Sciences, have been elected as Fellows of the American Geophysical Union for exceptional contributions in original research in climate change.

Inquiry into climate scientist moves to next phase

2/3/10

An internal inquiry by Penn State into the research and scholarly activities of a well-known climate scientist will move into the investigatory stage, which is the next step in the University's process for reviewing research conduct.In looking at four possible allegations of research misconduct against Michael Mann, a committee determined that further investigation is warranted for one of those allegations.

Harbingers of increased Atlantic hurricane activity identified

8/12/09

Reconstructions of past hurricane activity in the Atlantic Ocean indicate that the most active hurricane period in the past was during the "Medieval Climate Anomaly" about a thousand years ago when climate conditions created a "perfect storm" of La Nina-like conditions combined with warm tropical Atlantic waters.

"La Nina conditions are favorable for hurricanes because they lead to less wind shear in the tropical Atlantic," said Michael E. Mann, professor of meteorology, Penn State. When combined with warm tropical Atlantic ocean temperatures, a requirement for hurricanes to form, conditions become ideal for high levels of activity."

Climate change show features Penn State faculty

2/18/09

"How do we know? Physics, Forcings, and Fingerprints," the first episode of the National Science Foundation's "To What Degree? What Science is Telling Us About Climate Change" television series will premiere February 19 on the Research Channel with two Penn State climate researchers featured. Richard B. Alley, Evan Pugh professor of geosciences and Michael E. Mann, associate professor of meteorology and director of the Earth System Science Center were both interviewed for the show.

Review of 'Dire Predictions: Understanding Global Warming'

9/9/08

Global warming, increasing greenhouse gases and melting ice sheets are among the predictions made by the Nobel-Prize winning Intergovernmental Panel on Climate Change (IPCC), but comprehending the scientific assessments, their human impacts, and the possibilities for mitigation is not easy. Now, in a new book, Penn State climate scientists Michael E. Mann and Lee R. Kump digest the most recent IPCC reports into easily understood, sometimes amusing explanations and illustrations. "Dire Predictions: Understanding Global Warming" features all the graphs, images and eye-catching layout expected from international publisher DK Publishing, which specializes in popular illustrated reference books such as "The Way the Universe Works."

Global warming greatest in past decade

9/2/08

Researchers confirm that surface temperatures in the Northern Hemisphere were warmer over the last 10 years than any time during the last 1,300 years, and, if the climate scientists include the somewhat controversial data derived from tree-ring records, the warming is anomalous for at least 1,700 years.
