Your articles were interesting and they do add to our data base, but obviously further study is required. I would like to see the above research replicated and verified independently, not just reviewed. You are right, "we clearly don't know enough." I do find it interesting that with the elevated CO2 today we see none of the negative effects alarmists have warned us about.
