I'm not sure that stacks up too well on the evidence. What "warming" are you talking about? Typically, climatologists divide it up into the periods ~1880-1940, which is deemed to be due to natural factors, and from 1960 to the present, which is deemed to be largely due to anthropogenic greenhouse gases
OK, if we assume that human activity is now causing global warming, how do we know that in trying to reduce those activities we don't go too far and then cause global cooling?
