YES — CO2 HAS BEEN ON AN UPWARD CLIMB, to levels above those seen for the last few ice ages (with the proviso that ice cores records have poorer resolution the further back in time one goes; there may have been short - lived CO2 spikes that we can not see); is all of that human - driven, or is
there a natural warming trend driving the release of biotic CO2?
