"No possible decrease in Australia's emissions would have any significant impact on climate change caused by global CHG emissions. That is a simple empirical fact and has been pointed out ad nauseam."
Do you vote? What difference does you vote make? Have you ever heard the phrase "every vote counts"?
One cent on its own doesn't seem significant, neither does one share in a portfolio... but add them all up and the significance is important.
Your statement above is a nonsense as exampled by the unified action on eliminating H2SO4 emissions in the 70-80s, by eliminating chlorofluorocarbon emissions in the 80-90s to reduce the impact on the ozone layer.
Global unified actions repair the damage done by human pollutants. Australia's contribution is significant and actions are necessary.
