Climate change topic for Speakers’ Series


Pima Community College chemistry instructor Silvia Kolchens will discuss her climate change research at the Arctic’s edge during a Dec. 3 presentation.

Her talk, the final session of the 2013 Speakers’ Series, will take place at 6 p.m. in the Community Board Room of PCC’s District Office Building C at 4905 E. Broadway Blvd.

Kolchens will present her findings from two field research trips to Churchill, Manitoba, in Canada.

The presentation will include studies on soil analysis, snow packs, permafrost and the subarctic, and explain how it relates to global changes.

Kolchens has been a PCC instructor since 1995, and became the West Campus chemistry department chair in 1999.

She is an active member of the Southern Arizona section of the American Chemical Society. Other interests include astrochemistry and environmental chemistry.

Kolchens feels the media “bombards” citizens with second-hand news. She also believes people can step up and do something to make the world a better place.

Being more critical is essential to change, she said.

Silvia Kolchens will give the final Speaker Series presentation of the semester.
