Celestial influences on the climate

The Sun has a cycle of more or less 11 years during which it goes from low activity with a minimum of spots or none, to high activity with a large number of spots (at most about 200 spots) to return then to its minimum activity. The more spots the Sun shows us, the more coronal mass ejections it expels, gigantic clouds of plasma impregnated with magnetic field lines. Since the invention in 1610 of the astronomical telescope by Galileo, man has observed the mood of the sun by counting its spots and today viewing the activity of the Sun in greater detail thanks to new tools for astronomical observation ...

Solar activity is mainly reflected in permanent radiation of which we only receive a small part on our ground (the sun's rays which light up and warm us), by local increases in its magnetic field (sunspots, see the 2 shots above in gray) and by coronal mass ejection flares of a power that can vary from several thousand to several hundred million atomic bombs (eruptions visible on the videos above where the sun is masked to allow observe what is happening from its circumference). These eruptions expel jets of ionized matter which are lost in the solar corona up to hundreds of thousands of km in altitude with a propagation of several types of more or less intense additional radiation towards space and from time to time. time towards our planet. These different solar radiations that we receive are for the most part deflected by the Earth's magnetic field outside the Earth's field and towards the poles (creation of the aurora borealis), the other part being most often absorbed by our atmosphere.

As this graph shows, the more solar activity increases, the more the temperature on Earth also increases, and vice versa. Note the absence of solar activity in the second half of the 17th century, which corresponds to a "little ice age", the Maunder minimum, and the fairly weak solar activity at the beginning of the 18th century, the Dalton minimum. It is estimated today that the Maunder minimum would have been accompanied in the northern hemisphere by a drop in the global average temperature of about 1 degree °C.

A stream of atomic nuclei and high-energy particles, cosmic rays, reaches us from the depths of the universe and our own galaxy following certain chaos such as former deaths of stars (stars that can be at least 100 times larger than our sun) and which have given rise to supernovae. The magnetic field that protects the Earth deflects some of these cosmic rays out of the Earth's field and towards the poles, but the rest of these rays enter our atmosphere, causing ionizing reactions there.

4) Interaction between the solar activity and the cosmic rays

This graph represents the number of sunspots (line in dotted line)
and the intensity of the cosmic rays ( full line).
Note the anti-correlation between the intensity of the cosmic rays and the solar activity.

During periods of high activity, the Sun deflects some of the cosmic rays coming from deep space, thus sparing the Earth from some of this cosmic radiation. In 1997 Friis-Christensen and Svensmark announced a new theory according to which a stronger flux of cosmic rays would create a greater number of low altitude clouds which are relatively warm and composed of fine water droplets. These clouds would cool the planet by preventing some of the sunlight from reaching the Earth's surface. Conversely, during periods of high activity, the Sun deflects part of the cosmic rays coming from deep space, thus sparing the Earth from part of this cosmic radiation. The formation of low clouds on Earth is therefore reduced in this case and the Sun would then heat us more strongly during this period. This thesis has since found the support of a large part of the scientific community.

The Secret of the Clouds, a 52-minute ARTE documentary, presents several scientific studies that invalidate the official theory of global warming, a consequence of human activity alone. These studies scientifically demonstrate that the Earth's climate is mainly under the influence of the cosmos. (2007 vidéo - 52mn) https://www.youtube.com/watch?v=ANMTPF1blpQ

The global temperature on Earth has risen by 1°C since the end of the 19th century and we discover that this temperature has not increased for about ten years.

Since solar cycle 23 of high intensity, we have had cycle 24 of lower intensity and the current cycle which started in 2019 looks set to be even weaker. Also for some years some astronomers have been betting on future solar cycles of a much lower intensity than those we have known during the last 7 cycles from 1923 to 2007. All hopes are allowed : if temperatures have stagnated for 10 years, it is then logical to consider that the global temperature on Earth will soon begin to come down, certainly slowly but enough to evaporate the fear of global warming that some wants to see as inevitably catastrophic.
