Winter's not coming: Game of Thrones' Jon Snow worried over lack of it

Kit Harington describes a 'very sad irony' as the HBO show films in locations where ice is shrinking, even as his character fears the approaching winter

His character Jon Snow may fret about the arrival of winter, but Game of Thrones actor Kit Harington has said he was instead confronted by "terrifying" evidence of global warming while filming the HBO show.

Harington said it was a "very sad irony" to film in locations with diminishing ice for scenes where the arrival of winter, and the frosty undead from beyond the Wall, is feared by his character.
