In order to compare two things you need to know what both things are. While this "scientist" may have a theory on what the lack of sunspots means for Earth, he doesn't have any idea what "Winter is coming" actually means in Westeros because no one does. We think it means snow and ice moving further and further south but it could also mean darkening skies, lands full of white walker zombie type things or just plain-old-Death.

Sorry, I'll hop off my soapbox now

I have a lot to worry about, so I’ll just add this to the list.

Actually, it’s not a theory: the Sun has been shown to have a minor variability range of ~2-3%, and low sunspot counts have consistently correlated with a minima in solar flux.

Furthermore, astronomical records from the past two major minima (the Maunder and the Dalton) also correlate with historic “Little Ice Ages”, via multiple methods. Less detailed records also correlate high sunspot activity with higher solar flux: records from observations during the Medieval Climate Optimum also correlate high sunspot count with increase solar flux.

Sunspots are obviously not the cause, but ARE an indicator. . .

That’s what I think.
