I understand that, but first of all, they're not actually using these measurements for the purpose of dating, but for the purpose of measuring the levels of sunspot activities in the past. Even if the 8,000-year figure isn't accurate, it still would show that this is the most active sun in a long time.

Secondly and more importantly, regardless of whether or not this technique is valid for any purpose at all, the scientists believe it to be valid, which disproves the notion that there's a consensus in the scientific community that global warming is human-induced.

You still do not understand. These guys are using the same techniques to determine the extent of Solar activity that they use for dating finds. If one is valid, the other is, too.
