Brighter model for global warming
To environmental chemist Scot Martin, chemistry is a way of understanding the Earth and some of its most pressing problems. From global warming to heavy metal pollution in groundwater, Martin, named Gordon McKay Professor of Environmental Chemistry last July, is using the tools of chemistry to shed light on how natural processes interact with human…

Warming world would see fewer summer breezes
A group of climate researchers has shown that a warming globe over the next 50 years could result in fewer appearances of summer’s cleansing winds over the Northeast and Midwest United States, resulting in worsening air pollution in the regions. Loretta J. Mickley, a research associate at the Division of Engineering and Applied Sciences; Daniel…
