  Carbon dioxide levels are not at all high — they have been much higher in the past. Indeed, we are very fortunate to be living at a time of relative warmth, rather than during a little or especially a full-on ice age. Some leading scholars believe we are on the verge of another cold period – one that would be exacerbated by any cuts in atmospheric carbon dioxide levels.
  
  Meanwhile, demonizing this vital natural plant nutrient as pollution is not just absurd, it is anti-humanity.
