Global warming heats up in classrooms

The Register-Mail looks at how science teachers teach global warming with balance.

Excerpt:

Peter Schwartzman, chairman of environmental studies at Knox College, teaches climate change in an introductory environmental studies class that is filled with non-science majors.

“We focus a lot on the uncertainty of the science associated with the issue,” he said. “Students have to have a sense that there is more than one opinion on this.”

In a recent class, the 35 students discussed two articles they had been assigned to read – one saying global warming was real and one describing it as hooey. A general consensus from the wide-ranging discussion seemed to be a desire for more clear evidence to support both arguments rather than just partisan rhetoric.
