The question is whether anthropogenic global warming is the exclusive or dominant fact that determines our climate, or whether Corbyn is also right to insist on the role of the Sun. Is it possible that everything we do is dwarfed by the moods of the star that gives life to the world? The Sun is incomparably vaster and more powerful than any work of man. We are forged from a few clods of solar dust. The Sun powers every plant and form of life, and one day the Sun will turn into a red giant and engulf us all. Then it will burn out. Then it will get very nippy indeed.
