The article speaks of a Maunder Minimum type cooling, not a new "sudden Ice Age". Even at the height of the last ice age latitudes up to 38 degrees were free of glacial ice. Snowball earth was 600 million years ago and is not likely to be repeated over the next few election cycles.
Our present interglacial period has lasted longer (and been more stable) than any in the last several million years. Interglacials are normally short. It may be that humans have had some effect, in that regard, though also it is of note that temperatures in the current interglacial have NOT exceeded the peak of the last interglacial. If we have had an effect, it seems to be mostly a "buffering" effect, and no one can tell me anyone knows if the effect is enough to continue overriding the overall pattern. Similarly, no one really knows how much of a dip might trigger a greater drop.
Shoot, we were supposed to be rained on like crazy, yesterday, much of the day, and we got nary a drop.
