Amusing. In 1971, “top climate scientists” were screaming about a coming ice age and that CO2 was nothing to worry about, then, suddenly they were all about the warming. And the name James Hanson appears in both camps… What a coincidence.
In 1971, the world’s top climate scientists Schneider, Hansen and Rasool predicted that burning fossil fuels would trigger an ice age. They also determined that CO2 was nothing to worry about.
A few years later they realized that there was much more research money available for global warming, so they changed their scientific judgment to say the exact opposite of what they said in 1971.
