You evidently had to submit questions in writing, after which they were screened in some undisclosed way. I attended a James Hansen appearance in Minnesota where he ducked tough questions in the same way.
Penn State professor Michael Mann addressed climate change and global warming at the Penn State Forum Speaker Series.
The event was held at The Penn Stater and included lunch for more than 300 attendees before the program — which , said was modeled after the National Press Club — commenced.
Interim Executive Vice President and Provost Robert Pangborn introduced Mann, noting many of Mann’s accomplishments and credentials. Some of the credentials included winning the 2007 Nobel Peace Prize that Mann shared with other authors of Intergovernmental Panel on Climate Change Third Scientific Assessment Report in 2001 . Pangborn also emphasized how there is a significant amount of climate researching at Penn State.
“Mann is at the front,” he said.
...“I find it chilling that science is now a political football in an increasingly rancorous public discourse,” Mann said.
A Q-and-A session followed Mann’s speech. While most of the questions centered on Mann’s research and the criticism surrounding it, a few asked Mann to address the political aspects of the climate wars....Mann called himself a “reluctant warrior in the climate wars,” but embraces his role, and said he could think of no greater purpose than to assist in public outreach on the issue.
[Patty Satalia, senior producer for Penn State University Outreach], who had been reading the questions submitted by the audience to Mann, closed the program by reading a comment: “Thank you for a great lecture and thank you to the coal industry for free advertising.”
