Dear All,
I think this is a terrible comparison to make and should not be used. I
heard someone this summer who was trained by Al Gore use this and she
did not distinguish between all the effects of atomic bombs and the
energy equivalent of the atomic explosions.
Equating nuclear war and global warming is a false comparison. Nuclear
war is a much worse fate for our planet, and is a scare tactic. The
number is correct (I did the calculation myself when I first heard of
this), but trapping energy has completely different effects from
dropping nuclear bombs on people. Using this is distracting,
sensational, and easy to refute if the speaker does not carefully
explain that it is the energy released by the bombs, with no other
effects including radioactivity, fires, and blast.
I told John Cook this at the AGU Chapman Conference on Climate
Communication this summer, and he said he would consider this
recommendation, but I don't know if he plans to continue to feature this
idea on Skeptical Science.
But see

for another point of view.

It's actually 345,600 Hiroshimas/day or 4 bombs/sec, but you get the
idea. 90% of the heat is going into the ocean. This would seem a
powerful analogy (minus the radionuclides) for what we are doing to
the planet and why we need to intervene.
