SYDNEY, Australia — Even before the Copenhagen talkfest opened this week, a climatic wrangle cost an Australian political leader his job. Even before the expected international fallout from Copenhagen, Canberra is on alert for national electoral turmoil.

Jet-setting Prime Minister Kevin Rudd, having personally lobbied what seems like half the world's decision- makers, is pleased with whatever influences he has had in recent international sessions. At home he can justifiably take heart from the self-destructive forces engulfing climate change skeptics sitting on the opposition benches in Federal Parliament.

First to fall was opposition leader Malcolm Turnbull. The Sydney-based former merchant banker and barrister was ousted by fellow Liberal parliamentarians in a close leadership ballot. The trigger for the internal revolt was the climate change row that spotlighted Turnbull's guarded support for an emissions trading scheme (ETS). A majority of Liberal-National Party coalition parliamentarians say Copenhagen proposals are sure to penalize energy-rich Australia.
