Cold War collaboration on the greenhouse effect

NCAR founder Walt Roberts had already been an advocate of Soviet-American scientific partnerships for many years when he was invited by Robert Redford in 1988 to join a Sundance Institute conference entitled Greenhouse Glasnost. Top Soviet and U.S. scientists came together to explore the global impacts of climate warming. At the end of the week-long meeting they signed a joint resolution with recommendations for action, which was sent to USSR and US heads of state Mikhail Gorbachev and George H.W. Bush. Here, Roald Sageev of the Soviet Institute for Space Research, Rusty Schweickart of the Association of Space Explorers, and Roberts enjoy informal conversation at Redford’s rustic mountain resort.
