I see that last week, Harry Clarke (at his temporary blog) posted a review of a book by Richard Tol.
Given that Harry only recently pointed out at his old blog where his temporary blog was located, I was surprised to find that Tol himself had already appeared in comments complaining about Harry's rather mildly worded review.
This suggests Tol likely spends a fair amount of time Googling up his own name for references to him, no matter where they appear.
It also appears that Harry does not know of Tol's reputation for attacking people he disagrees with. Harry should do some searches for references to him at Rabbett Run, and And Then There's Physics, and elsewhere.
And elsewhere, I see Tol weighing in on a ATTP post about Matt Ridley's complaining column in The Times that he's unfairly attacked for being a "lukewarmer".
I think Richard has too much time on his hands
