Tom, Google Scholar will find lots on using C14 as a tracer, e.g. if
you search
  C14 "carbon cycle"

Example:

Nothing popped up suggesting there's any climate effect from the above-
ground testing, but I didn't look deeply.

I do recall the 'nuclear winter' studies, both the first ones and the
recent new 'nuclear autumn' round, are talking about the lower level
smoke and soot expected from extensive fires; I would guess the
projection assumes extensive vaporization and fallout created by
fireballs near ground level that would preclude firefighting, not
airbursts like Hiroshima and Nagasaki.  More like
