Topic: The Sun and solar cycles
I recently watched "The Great Global Warming Swindle".
It is a documentary that describes the correlation between sun temperature and earth temperature. From that, I looked into solar cycles.
Here is a link to the Wikipedia article about "The Sun":

Here is a section about the Sun's Magnetic field:
Magnetic field
All matter in the Sun is in the form of gas and plasma because of its high temperatures. This makes it possible for the Sun to rotate faster at its equator (about 25 days) than it does at higher latitudes (about 35 days near its poles). The differential rotation of the Sun's latitudes causes its magnetic field lines to become twisted together over time, causing magnetic field loops to erupt from the Sun's surface and trigger the formation of the Sun's dramatic sunspots and solar prominences (see magnetic reconnection). This twisting action gives rise to the solar dynamo and an 11-year solar cycle of magnetic activity as the Sun's magnetic field reverses itself about every 11 years.

Apparently the sun has an eleven year cycle.
Here is the calendar of recent solar cycles:
June 1976 September 1986
September 1986 May 1996
May 1996 circa2007
circa2007 circa2018
According to this schedule, we are currently ending one solar cycle and starting a new solar cycle.
