Researchers from the Universities of Bristol, Cardiff and Southampton used a model to simulate the climate of Game Of Thrones.
Scientists have come up with a theory to explain the strange, extended seasons – where summer can last for years – in the world of hit fantasy drama Game Of Thrones.
They estimate a warming of 2.1C for a doubling of carbon dioxide – the climate sensitivity of the world of Game of Thrones.
Temperatures predicted by the climate model indicate the likely hibernation zones of the White Walkers during the summer.
