SYDNEY: Even a small-scale, regional nuclear war could produce as 
many fatalities as all of World War II and disrupt the global climate 
for a decade or more, U.S. researchers have found.

"With the exchange of 100 [hiroshima-sized] weapons as posed in this 
scenario, the estimated quantities of smoke generated could lead to 
global climate anomalies exceeding any changes experienced in 
recorded history," said co-author Alan Robock, of Rutgers Univeristy 
in New Jersey. "And that's just 0.03 per cent of the total explosive 
power of the current world nuclear arsenal."
