The Sun has now entered a period of low activity associated with collapsing temperatures and this change could last a decade or more. Astronomers say that the sun has now spent 15 consecutive days without sunspots, sign of the decline in activity. It also means that there has been a lack of sunspots for 58% of the days in 2019.
The sun follows cycles of about 11 years, where it reaches a solar maximum and before going to solar minimum.
During a solar maximum, the sun gives off more heat and is covered with sunspots. Less heat in a solar minimum is due to a decrease in magnetic waves and fewer sunspots.
The Space Weather cosmic forecast site said: "The sun has been spotless for 15 consecutive days – a sign that Solar Minimum is underway."
Some climate scientists, however, believe that solar cycles pose a greater threat to our planet than global warming caused by man.
Vijay Jayaraj, an environmental scientist with the Cornwall Creation Stewardship Alliance – a Christian group that rejects artificial global warming claims – believes there is evidence to suggest that global warming is actually caused by the cycles of the Sun.
"Life on Earth is possible thanks to the perfect positioning of the Earth in the solar system: not too close to the sun and not too far away. Academicians have recognized it for centuries and climatologists today know that the sun is the most determining and determining factor in the temperature of the world.
"NASA's Solar Influence page clearly indicates that changes in the sun largely determine the atmospheric and surface temperatures of the Earth.
"Astrophysicists and climatologists measure these changes in the sun in terms of quantifiable phenomena such as sunspot activity and solar cycles.
"With the advent of the theory of global warming, dangerous and artificial, CO2 has attracted attention, and the sun has been relegated to the rank of mere spectator.
"This is perhaps the biggest mistake of all alarmists, obsessed with warming.
"In Central Europe, for example, the temperature changes since 1990 have more coincided with the changes in solar activity than the concentration of atmospheric CO2. The same has been true globally and across the centuries. "
The Earth's host star is not expected to reach the solar minimum by 2020, and if the phenomenon occurs early, it will mean a prolonged cold spell.
The last time there was a prolonged solar minimum, the event had led to a "mini-age of ice," scientifically known as the Maunder Minimum – which lasted 70 years.
The Maunder Minimum, which has experienced seven decades of icy weather, began in 1645 and continued until 1715, and occurred when sunspots were extremely rare.
During this period, temperatures fell overall by 1.3 degrees Celsius, resulting in shorter seasons and ultimately food shortages.
In the end, if the sun has to go through a prolonged solar minimum, it is the humanity that could suffer from it.
NASA explains on its website: "All times on Earth, from the surface of the planet to space, begin with the Sun.
"Spatial and meteorological terrestrial weather (the weather we feel on the surface) is influenced by the small changes the sun undergoes during its solar cycle."
The Space Agency adds to its Thermosphere Climate Index (TCI) "a meteorological metric indicating how the top of the earth's atmosphere (or" thermosphere ") reacts to solar activity", according to which "the top of the Earth's atmosphere is about 10 times colder than it was during the 1957-1958 Solar Max record.
