What is the Sun’s Role in Climate Change?

The Sun powers life on Earth; it helps keep the planet warm enough for us to survive.
It also influences Earth’s climate:
We know subtle changes in Earth’s orbit around the Sun are responsible for the comings and goings of the past ice ages.
But the warming we’ve seen over the last few decades is too rapid to be linked to changes in Earth’s orbit, and too large to be caused by solar activity.
