Game of Thrones season 6 is almost upon us and along with winter, the White Walkers are also coming...

... or are they?

In case you didn't get it, the Greenpeace advertisement targets climate change. 

The caption reads: "A few more degrees can change the story" - referencing the frozen 'White Walkers' from popular TV show Game of Thrones.

All the Night's Watch needs to do to get rid of the blue-eyed icy killers is to start an industrial revolution, install a few air conditioners and do what regular humans do.
