The information in the article is based on a peer-reviewed paper from two Russian scientists, who looked at the real world data and trends, as well as the solar processes, and say that this could lead to a climate similar to the Little Ice Age (PS for Warmists: it’s not just about sun spots, but the overall activity of the Sun along with its magnetism).It's that big yellow thing in the sky.
Again, to be clear, until it happens, it’s all conjecture. Just like the notion that this current warm period is caused by Mankind. Well, except that the climate does switch between warm and cool.
