He pretends to be so "holier than thou" about the climate crap, but then he actually tries to defend his use of private air travel.  He owns a jet (YES HE DOES) and his wife owns one, too.  Just look it up.  It's not hard to find the evidence of what a crackpot liar this joker really is.

I keep asking why they aren't working on Electric airplanes and electric helicopter, etc???  Isn't that their biggest worry?  We all gotta have electric cars which are a complete non-starter in certain areas of the USA, but they don't seem very interested in working on the problems coming from the worse of "polluters" - - if you actually believe their nonsensical rants.
