I think this is mistaken, as I read the report:

< roughly follows a 1,500-year pattern, based on analysis of the past
12,000 years. But the difference from the top of the cycle to the bottom is
very small, with less than a 0.1 percent difference in energy levels >

I.e., +0.00007% per year. But maybe that's not what Bond means, since
surely so small an effect would be impossible to detect... well, except
cumulatively, which is what the report seems to claim.
