This is true for Brazil also. I saw something about periodic sunspots affecting the temperature. Supposedly, this will be a cold winter. I think it's accurate and seems like rational science.

Professor Valentina Zharkova at Northumbria University is being attacked by climate change proponents for publishing research suggesting there could be a 35-year period of low solar activity that could usher in an “ice age.”
Zharkova and her team of researchers released a study on sunspot modeling, finding that solar activity could fall to levels not seen since the so-called “Little Ice Age” of the 1600s. Zharkova’s conclusions may have huge implications for global temperature modeling, but her analysis is not accepted by some climate scientists.
In fact, Zharkova said some scientists even tried to have her research suppressed.

She suggests it could be a repeat of the so-called Maunder Minimum – a period in the 17th century with little solar activity that may have influenced a cooling on Earth.
Whatever we do to the planet, if everything is done only by the sun, then the temperature should drop similar like it was in the Maunder Minimum. At least in the Northern hemisphere, where this temperature is well protocoled and written. We didn’t have many measurements in the Southern hemisphere, we don’t know what will happen with that, but in the Northern hemisphere, we know it’s very well protocoled. The rivers are frozen. There are winters and no summers, and so on.
So we only hope because these Maunder Minima will be shorter, the Maunder Minimum of the 17th century was about 65 years, the Maunder Minimum which we expect will be lasting not longer than 30-35 years.
Of course things are not the same as they were in the 17th century – we have a lot more greenhouse gas in the atmosphere. And it will be interesting to see how the terrestrial and the solar influences play out.
This is promising research – a new insight into our sun with predictions as to its future behavior, yet Professor Zharkova relates than some climatologists resented her discovery.
