Occasionally amidst the chaotic hyperbole of the climate change debate a lone voice of reason can be heard above the din. Yesterday it came from former ALP minister Gary Johns who condensed the politician's job in the face of scientific uncertainty on climate change to two simple words: "buy time" (Don't count your trees, forests aren't that green, The Australian 4/2).
In contrast our current Government and the Opposition leap blindly over the barricades, chasing phantoms yet to crystallise from the miasma. When these demons finally coalesce, sometime in the distant future, one only hopes that our leaders pre-emptively left home with the right tools for the job, and not with a bag full of uncircumscribed programmatic specificity.

Geologists know the climate changes but sadly it seems politicians and the press are more willing to trust the results of incomplete computer models. Climate models are useful but while they are in an early stage of development its best to take a skeptical view of their output.
