During an upcoming American Chemical Society meeting, a University of Arkansas at Little Rock chemistry professor will make a case for the collection of more climate change data.

In his featured lecture, Dr. Jeff Gaffney, an expert in the chemistry of climate change, will discuss the potential effects of ethene and the need for baseline measurements across the country to help determine if new energy technologies are having the desired effects.

The combustion of ethanol/gasoline blends increase emissions of ethene, aldehydes, methane, and nitrogen oxide compared to gasoline alone, according to Gaffney’s presentation abstract. Gaffney said it’s well known that ethene is an air pollutant that can damage plants and agricultural yields.

His talk at the American Chemical Society East Texas Section meeting is scheduled for 7 p.m. Tuesday, Nov. 17, at the Truman Arnold Center at Texarkana College.

Gaffney, the chair of the UALR Chemistry Department, is an internationally respected chemist known for his atmospheric, environmental, biogeochemical, nuclear chemistry, and climate change research.
