In grade school I wrote a report following The International Geophysical Year (IGYYJuly1957, to December 1958 following up on earlier 1954 report I did about the scientific study of Antarctica. I embraced the Gaia hypothesis and concluded that humans had already reached the tipping point. I've viewed the reality of that conclusion unfold for the last 60+ years.. gratefully I'll be dead before the really bad sh!t hits the fan.
