Is every Leftist "scientist" a liar?

Or just the popular ones?

Another Neil deGrasse Tyson bollocksed up science anecdote, as emailed to me by PJM’s own David Steinberg:

And this is on top of the anti-Bush screed that Tyson put out that was shown to be a pack of lies as well.

Neil deGrasse Tyson may be a fabulous scientist, and a consummate showman, but he’s downright terrible at accurately quoting people. Or, if you’re a “glass half full” kind of person, you might say that Neil deGrasse Tyson is pretty amazing at needlessly fabricating quotes and scenarios to showcase his own brilliance.

We’ve already established that a newspaper headline touted for years by Tyson likely doesn’t exist. We’ve also established that the exact quote he uses to bash members of Congress as being stupid also doesn’t exist. And then we established that the details within one of Tyson’s favorite anecdotes —a story of how he bravely confronted a judge about his mathematical illiteracy while serving on jury duty — seem to change every time Tyson tells the story. 

Every time you turn around, another Leftist "scientist", or the people who claim to use science, are shown to be liars.  Arctic Pack Ice, anyone?  Didn't algore, aka Pope Prius the First, claim that all the Arctic ice was going to be gone by now?  Not just less of it, but gone, as in no more.  And yet we had record levels of ice in the Arctic last year.  This year?  Record levels of ice in the Antarctic ice shelf.  So much for all that "The ice is gonna melt and we're all gonna die" meme, eh?  But get this:  Even in the article talking about record levels of sea ice in Antarctica, there are still people TALKING ABOUT GLOBAL WARMING!!!!!

So, are all Leftist scientists liars?
