Hey, it's not me in my mom's basement telling you "the end is nigh" but rather a team of scientists, including NASA members, telling you! Solar minimum is a known quanity. We are now in the very beginning (2017) of a grand solar minimum. We'll be lucky to be coming out the other side by 2030.
Ice ages have occurred in the past, as have solar minimums. The nice thing about this type of event is the evidence they leave behind in core samples -- highly reliable and readily available for study. It's no conspiracy theory that these things have happened. It's not up for debate.
