This week’s pic is of Istanbul’s famous Galata tower last Saturday evening, ahead of its lights being switched off for an hour, in aid of the Earth Hour movement. Earth Hour was started by the WWF in 2007, now millions of people around the world set aside an hour at the end March between 8:30 and 9:30, to switch off their lights in a fight against climate change.

ELT teachers, how do you discuss climate change in the classroom?
