increase the volume and mass of natural plankton.

ii) We see an
increased tropopause height above the rising column but, as described above, that
induces a decreased height above the descending column so that the surface below the descending column
warms up less during adiabatic descent than would otherwise have been the case.
«In considering the question of human activity and climate change it is essential to distinguish between global
warming, which is a progressive
