Speaking of climate change, parts of this story just astound me:

Prior to the industrial revolution, the sun probably accounted for about 10 to 30 percent of climate variability, Hathaway told SPACE.com, but now that greenhouse gases have started to build up, “the sun’s contribution is getting smaller and smaller,” he added.

Yes, it seems clear that the Sun is only a minor factor in our climate conditions. How could anyone think that an inconceivably massive nuclear furnace that bathes our planet in a constant wash of radiation and magnetism is important?

The good news is that if this trend continues, and the Sun’s contribution really does keep getting smaller, eventually it will become entirely irrelevant, and we won’t need a Sun at all.
