The author claims unequivocally that global warming is a hoax. Submitted as evidence is a page which one-sidedly discusses troubling, suspicious, and unseemly behavior by some climate scientists. That is bad, but not proof of a hoax--not by a long shot. Such a strong claim supported by such a weak source makes it appear (at least to the skeptical) that the author may not be equally skeptical of all sources or points of view. Confirmation bias is a known bug in the wetware which makes it hard to be truly objective about anything, try as we might.

Had the author made a weaker claim I'd have read the rest of the article with much less skepticism!
