Our beloved Sun has disregarded recent models of solar activity, and inspite of scientists' prediction, of going in high activity it's going into a weak phase. And I really mean a very weak phase.
Besides esthetic changes, like a lack of sunspots, the sun becomes cooler in during weak activity. Because 99.999 of all energy on earth comes from the sun, it will have a pronounced effect on our planet.
This low activity can be equal to Maunder Minimum from the year 1645 to 1715. Times of little ice age, when Baltic Sea was frozen solid every winter.
Are we going into little ice age again?

To be honest, this scientist also predicts that this weak phase won't stop anthropogenic effect of global warming. However, we might take all of this with a grain of salt, because he was wrong in his predictions before.

That's right, yeah. And the sun tends to go through these longer cycles like that. Again, there's an 11-year cycle of activity, but there are big cycles and small cycles, and they tend to grow and then get small again. There's about 100-year periodicity in that, that at the beginning of the 20th century we had a couple of small sunspots cycles. And at the beginning of the 19th century we had two really small cycles.
The beginning of the 18th century, we were just coming out the period of 70 years without sunspots, where it's been called the Maunder Minimum.
But it may be longer. In fact, a number of my colleagues have suggested that perhaps, or certainly there's the possibility that we are heading into another one of these long, grand minima like the Maunder Minimum. You know, the Maunder Minimum from the year 1645 to 1715, and it was 70 years, virtually, without sunspots. There were a few that started taking up near the end. But, basically, as far as sun spots, the sun stopped doing it for 70 years.
It comes at the end of what is called the Little Ice Age for climate. And both that minimum and the minimum at the beginning of the 19th century correspond to cool times in Earth's climate. It has led us to believe that the sun does - the solar variability, I should say, this, you know, coming and going of sunspot cycles - does influence climate to some extent. And the big question is to how big an extent. And there's a wide range of feelings on what that is.
To be honest, this scientist also predicts that this weak phase won't stop anthropogenic effect of global warming. However, we might take all of this with a grain of salt, because he was wrong in his predictions before.
