bottletop, it's unclear how much of an impact the CO2 increases we are experiencing is having on our climate. Also, any such impact may well be counterbalanced by nature. We just simply don’t know, please believe me. I’ve discussed this with numerous scientists. If we did know even with any reasonable certainty all the scientists would be in agreement (except perhaps for a few perma sceptics) and we would be formulating appropriate plans to solve the issue, if indeed there is any to solve, or even if it’s in our capacity to solve, in particular if the cause(s) is(are) out of our control.
