With a title "To an alarming degree..." it immediately feels like a persuasive paper. Who thinks it's alarming? From the sound of it, everyone should (or does) think this is alarming.

But it may be a stretch to say this is someone trying to discredit global warming.

Science isn't broken. People claim what they see, sometimes they are wrong, sometimes they are right. But eventually we find out the truth.
