It's interesting because it is based on solar cycles, but lots of research has shown solar cycles alone don't account of the warming of the 20th century. Maybe anthropogenic warming and solar cooling will perfectly balance themselves out
I will say I agree that other than catastrophic Venus style runaway GW, an ice age scares me a lot more than a 5-10 degree rise in temperatures. Especially considering the record shows ice ages can begin very rapidly, and last a lot longer than the food I have in my basement.
