well, the nuclear tests did not have clear impact on the climate, at least in a long run, but they had strong impact on the proportions of the radionuclides present in the atmosphere ... the C14 was one of the most affected. the thermonuclear bombs added large quantities of 14C to the atmosphere, mainly during the 1955-1963 period. you can see evolution of the 14C on the atmosphere here: http://www.iup.uni-heidelberg.de/institut/forschung/groups/kk/en/14CO2_html on direct consequence is that the atmosphere now has an apparent age of about 70 years in the future. you can find more info on this here: http://www.ingentaconnect.com/content/arizona/rdc/2004/00000046/00000003/art00019 Discussion: Reporting and Calibration of Post-Bomb14C Data Authors: Reimer, Paula J.; Brown, Thomas A.; Reimer, Ron W.
