Earth-climate relationship of space weather.

Compared with the energy of solar visible light and infrared electromagnetic radiation, the total energy of all space weather phenomena entering the troposphere and stratosphere of the earth's atmosphere is negligible. However, there does seem to be some connection between the quasi 1 1 annual cycle of sunspots and the climate of the earth. For example, maunder minimum, where there has been almost no sunspot activity for 70 years, is related to the cooling of the earth's climate. For this connection, there is a saying that the change of cosmic ray flux will change the number of clouds formed. To put it another way, the driving source of the earth's climate is very sensitive to the change of solar extreme ultraviolet flux, which will determine whether El Ni? o or La Ni? a phenomenon occurs in the Pacific Ocean. But whether the two are related is still inconclusive.
