Why would an Apollo Astronaut come out of retirement to jump off a cliff in Peru?
For Apollo 7 astronaut Walt Cunningham, calling attention to the “sorry way” that climate science and policy have been distorted is an important reason.
Walt came to the UN climate conference in Peru (COP 20) as part of the official CFACT delegation to issue a call for political leaders and the media to return to “scientific realism” on global warming.  Cunningham was part of the three member Apollo VII crew which in 1968 became NASA’s first manned space mission after the loss of the three astronauts of Apollo I to a tragic fire on the ground.
82 year old Cunningham became so “fed up,” with the endless character assassination, lies and distortions that permeate the global warming discussion that in 2012 he joined with several of his colleagues to find out what America’s pioneers in space think about the issue. They found themselves to be united nearly unanimously in opposition the global warming alarmist campaign with the main division coming between those who were willing to say so publicly and those who expressed their opposition behind the scenes.
