Here’s Leonard Nimoy’s narration of climate change in 1978:
Leonard Nimoy said "it is the worst cold recorded in the last 40 years"
Hmmm.... 1977-40= 1937
Notice that "climate scientists" in 1977 were CONVINCED that the next Ice Age is on its way.
If you can't trust Spock to know what he's talking about, who CAN you trust?
