Anthony Watts, or one of his surrogates, has made a brief appearance at WUWT to write a headline and an opening salvo. Here is what he wrote (archived here):

That's it. The rest was a copy and paste of an article from NOAA (archived here). The NOAA article was about how there have been no tornadoes reported in the USA this March, so far. This is a record - since 1970 at any rate.
Anthony Watts talked about a "meme", but what he wrote is a logical fallacy known as a strawman, as you'll see below.
