What the heck. I -- of course there's a lot -- look, global warming needs to be taken very seriously, and I take it seriously. But science, there's a lot -- there's differing opinions. And before we react, I think it's best to have the full accounting, full understanding of what's taking place.
Having a true full understanding and full accounting of global warming is beyond our reach.
No matter how much we think we know about global warming.  We can never truly understand every last detail.  Most or our ideas about the phenomenon are based in theory.  Truly knowing something, anything really, is beyond human intelligence.  I'll refer to Goedel's Theorem and also the Heisenberg Uncertainty Principle.  The system probably can't distinguish this fact between having good evidence and certainty.
