things like ~ greater respiratory system problems, occurances of photochemical smog (more incidence around the world), more occurance of acid rain etc etc...

reliably tangible data is not really available yet, because humanity only taken serz attempt to control the level of NO x and SO 2 recently (starting i believe from the 50's)... the data is of short terms, and even there are increases in the level of SO 2 and NO x, many argue that's the seasonal variation, not caused by human activities...

continuing xiao's stuf, tangible data ain't reliable yet coz its only been around for like tha last 40 years n NOx SOx r highly soluble so they get flushed outa tha atmosphere regularly. But yeh, u can look at other mo 'natural' evidence such as increases in photochem smog, acid rain, incidence of asthma, etc.

or you could say

gas trapped in ice sheets in Antartica thousands of years ago was obtained
and compared the amount of NO and SO of present days and there was a considerable increase
