2010 Earth Hour in Budapest

The dramatic dimming of city lights during Earth Hour 2010 is revealed by taking identical photographic exposures of Budapest and Danube river before and during the event. Earth Hour is a global event organized by World Wide Fund for Nature and is held on the last Saturday of March annually, asking households and businesses to turn off their non-essential lights and other electrical appliances for one hour to raise awareness towards the need to take action on climate change.
