Co-founder and Chair of the co2coalition.
And is an infinitesimal percentage of the atmosphere.
But you idiots are experts at moving goalposts.
I have had a conversation with William Happer several years ago and I can tell you from first hand experience that even then he suffered badly from dementia and/or Alzheimers.
