Twilight sets on Auckland as it approaches Earth Hour (top) and the lights go off on Auckland as it enters Earth Hour (bottom) March 27, 2010 in this combination picture. Earth Hour, when everyone is asked to turn off lights for an hour from 8.30 p.m. local time, is a show of support for tougher action to confront climate change.
