In about an hour, it will be Dublin’s turn to participate in Earth Hour. The event started last year in Sydney when residents and businesses turned off their lights for one hour as a statement about global warming. This year, 28 cities will participate, each at their 8 pm on March 29. The event is described as a way to highlight “simple changes that will collectively make a difference.”

I thought this was a good opportunity to post some Dublin at night photos before we have to turn off the lights here. They’re beautiful scenes, but also remind us of the energy demands of modern cities.

I hope that Earth Hour will live up to its expectations, but fear that it may turn out to be no more than another fun event and a way for all of us to feel good, without addressing the fundamental changes needed to treat our planet and our children more kindly.
