There is a proposal in place that may save us from the most drastic effects of CO induced global climate change - that of introducing what is essentially massive amounts of sulfuric acid into the upper atmosphere, which will reflect a percentage of the solar radiation hitting the earth before it is retained by the CO blanket. While this will do nothing to change the immediate acidification of the oceans due to CO absorption, it would have a temporary cooling effect and may dial back the damage by 50 years. Unfortunately this process will kill millions of people - but doing nothing may kill billions. This is the dilemma we now as humanity face. The link below talks about the reactive nature of sulfuric acid - and may be interesting to those of you who want to know about it's role in our atmosphere.
