There have been many fan theories about Game of Thrones and George R.R.Martin has just confirmed one to be true: is the upcoming onslaught of icy White Walkers a metaphor for climate change?

When the GoT writer was recently asked if climate change has inspired the 'Winter Is Coming' angle of the plot, Martin confirmed that "in a very broad sense — there’s a certain parallel there."

"And the people in Westeros are fighting their individual battles over power and status and wealth. And those are so distracting them that they're ignoring the threat of 'winter is coming,' which has the potential to destroy all of them and to destroy their world.

"And there is a great parallel there to, I think, what I see this planet doing here, where we're fighting our own battles. We're fighting over issues, important issues, mind you — foreign policy, domestic policy, civil rights, social responsibility, social justice. All of these things are important. But while we're tearing ourselves apart over this and expending so much energy, there exists this threat of climate change, which, to my mind, is conclusively proved by most of the data and 99.9 percent of the scientific community. And it really has the potential to destroy our world.

So really, climate change should be the number one priority for any politician who is capable of looking past the next election. But unfortunately, there are only a handful of those."
