The lights go out in Sydney

The bright lights of Sydney went dim last night as the city promoted Earth Hour to encourage residents of the Australian city to reduce their CO2 emissions and thereby reduce global warming. The Aussies have their work cut out for them as they come second, among major nations, in per capita CO2 emissions after the US and ahead of Canada where home heating is more of an issue.

There were no reports of anyone in Sydney switching off the air conditioning.
