Dr. Steve Schneider was inspired to be involved in climate change and global warming in part because of Earth Day.
Like his eco-ally Carl Sagan, Schneider was a scientist able to Successfully get information to the public. Sagan had his television show Cosmos (recently revitalized by Neil deGrasse Tyson and Sagan’s widow, Ann Druyan—check your local listings).
Schneider wrote popular science books, did radio interviews around the world and appeared in movies and on television.
Here he is with Johnny Carson on The Tonight Show on July 19, 1977. Clip courtesy of UCAR/NCAR.
