Sun activity is declining in 2020: how will this affect the Earth?

Scientists have confirmed that our star is in the “solar minimum” phase, in other words, solar activity has suddenly significantly weakened.

Experts are already guessing and most of them agree that our planet will not ignore the consequences of this decline inactivity.
Should we really expect the approaching cold weather, earthquakes, and famine?

What is the danger of the Sun’s decline in activity?

As it became known, the sunspots almost completely disappeared quite quickly. Astronomer Tony Phillips believes that this event shows the deepest decline in solar activity in the last century. The solar magnetic field has become very weak and this could allow cosmic rays to penetrate our system.

In that case, for example, we can expect severe thunderstorms and a relative temperature drop. There could be complications with space technology and astronauts. But that’s not what’s most dangerous about reducing solar activity.




Some experts believe that the “solar minimum” period is a regular phenomenon in our star’s cycle and is observed every 11 years. However, most astrologers and experts recall with horror the beginning of the XIX century, when the decline of solar activity has led to a large number of disasters on our planet.

For example, remember at least the period from 1790 to 1830, which peaked in 1816. It went down in history as “a year without summer”, and the forty years period itself was called “the small glacial period”.

In “a year without summer” the world temperature decreased by several degrees, which hit first of all the agriculture. In addition, the year before, the most powerful eruption of the Indonesian volcano Tambora occurred. The volcanic ash hangs in the atmosphere, depriving our planet of much sunlight. As a result, 1816 was unusually cold – snow fell repeatedly in the middle of summer in European countries, and rivers were frozen throughout the winter. Of course, this affected the lack of a crop, which led to famine and almost a food war on all continents.

The second example of the Sun’s decline to a minimum level was the second half of the 17th century. At that time, temperatures remained low for as long as seventy years, summer was cold and all European rivers were steadily frozen. Presumably, the volcano eruption also contributed to this situation.

Could the cataclysms be repeated in 2020?

Given the previous periods of decline in solar activity and the consequences for our planet, we could start preparing for a long period of cooling. But world scientists don’t confirm this prospect.

Matthew Owens, Professor of Space Physics, is confident that this year’s global catastrophes and disasters will not bring about a reduction in solar activity:

“Of course, solar activity is at a deep minimum today, but there’s no ice age for our planet to fear. The Sun’s activity falls to this level every 11 years, it is part of a normal solar cycle. The last time such a minimum was in 2009-2010, but we are all alive”.

Astrophysics professor Jeff Knight is more pessimistic about this situation:

“It cannot be denied that the sunny minimum will have severe weather effects in winter. Probably, decrease inactivity of the Sun will lead to some fall of temperature on our planet, but hardly cools down cardinally, degrees on 15. Besides, the phenomenon of solar minimum does not cross out the fact of global warming”.
