Tom, Google Scholar will find lots on using C14 as a tracer, e.g. if you search C14 "carbon cycle" Example: http://www.osti.gov/energycitations/product.biblio.jsp?osti_id=5982486 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.
