Former astronaut: 'Hundreds of different factors' affect climate, not just humans

Apollo astronaut Walt Cunningham beamed into a climate change forum in Poland last week with Skype technology to discuss humanity’s role in global warming.

Cunningham, who was part of the Apollo 7 mission to the moon, addressed about 200 residents from the area in and around Gliwice, Poland, at the John Paul II Center on Dec. 12. The event was co-sponsored by the Committee for a Constructive Tomorrow, a nonprofit based in Washington, D.C., and Poland’s Globalization Institute Foundation, a local think tank.
