I'm really surprised that Dartmoor has caught fire, given the amount of
rain we've had and the cold weather. What is burning?

Winter moorland fires are not uncommon. Very cold weather dries the
foliage out just as much as very hot weather. In this case, it is in a
very remote area and moving towards a river valley, where it is expected
to burn itself out.
