Not well written (and I'm never surprised by poor writing in popular science articles).

That last item should probably be expressed as, "Prior to the Industrial Revolution, variability of solar output probably accounted for 10-30% of climate variability."

Don't you think? Another way to say it is that prior to the Industrial Revolution, external forcing from the Sun accounted for about 30% of climate variability, and internal forcing (volcanoes, El Nino, AMO, PDO, snow and ice cover, etc.) accounted for the other 70%.

So what you're saying is that climate "scientists" can write either...?
