That’s the only explanation for SkS to tweet about “Doonesbury cartoon on climate deniers http://bit.ly/xNSUsx“.
Here’s the strip:

Obviously, John Cook and friends are completely unaware of a few things about their own site:
- It’s built to reach out to climate newbies
- It’s where believers in (catastrophic) anthropogenic climate change go in desperate search of “evidence” to “support their position”
- It’s the one site sporting the belief “everyone is entitled” to read a single set of “facts” as determined by John Cook and friends
- It sports thousands of “facts”
It all looks like a heroic case of irony failure. Unless Doonesbury is so clever as to subtly indicate where the denial of science actually is…at Skeptical Science, of course.
