ITHACA, NY — According to a 2007 Business-Higher Education Forum report, there will be a shortfall of more than 280,000 math and science teachers nationwide by 2015. This negative impact on the ability of American students to think critically in science, technology, engineering and math will be felt most in high-needs school districts. To answer this challenge, five faculty members...
ITHACA, NY — Beth Ellen Clark, associate professor and chair of the physics department at Ithaca College, has received a $2.7 million grant from NASA to support her participation in the first U.S. mission to bring samples of an asteroid back to the Earth for study and analysis. Named OSIRIS-REx (Origins Spectral Interpretation Resource Identification Security-Regolith Explorer),...
Thusday, May 5th at 5:00 PM in the Klingenstein Room Physics Alum, Eric Leibensperger, '05, will give a talk on“Interactions Between Air Pollution and Climate: The Unintended Consequences of Cleaning Our Air”: The US Environmental Protection Agency (EPA) has implemented increasingly strict regulations of air pollutants such as ozone and particulate matter (PM). Ozone and PM have been regulated due to their adverse health effects and contribution to acid rain. However, these air pollutants additionally affect climate by scattering solar radiation (PM) and enhancing the greenhouse effect (ozone). Regulations have significantly improved air quality in the eastern US, but at what climate cost? I use observations and a global climate model to show that PM air pollution shielded the US from realizing the full effect of manmade global warming between 1950 and 1980. After 1980, EPA mandated regulation of PM removed the cooling effect, resulting in rapid increases of surface air temperature in the eastern US.
