The Sun is apparently the dimmest it’s been for over a century – see ‘Quiet Sun’ baffling astronomers. The reduced energy output from the Sun could be offsetting the impact from the greenhouse effect to a certain extent, just like “Global Dimming” did with particles in the atmosphere before the clean air acts.

What worries me, is what happens when the Sun cycles round and warms back up? Do we get much more rapid global warming, as the dimming effect goes away?
