Global warming, the greatest threat since that other greatest threat just before it

Here.

Excerpt:

...CBS environmental reporters have shown remarkable imagination. Consider Scott Pelley, whose global warming alarmism is so ham-fisted that when asked in a (not wicked funny) interview with colleagues about his bias he explained the he doesn’t need to seek the other side of the story because skeptics are like Holocaust deniers, who he has no need to interview.

Of course, that not long after making this claim he flew halfway around the world to actually interview Holocaust-denying Mahmoud Ahmadinejad only further confuses his analogy. Anyway, it seems the real kind is apparently okay.
