i have a bit of knowledge regarding solar dynamics. this is a very good and sobering presentation. there are other data that also support this theory, some of it quite difficult to grasp (mathematically, Russian sources). anyway, Ben does a good job here, it's not schlock. his youtube channel has excellent video learning resources, if you've not heard of him, i recommend you linger on his channel. many of the things he focuses on i've been tracking for decades (ya, im old)
