Solar activity was low in recent years, but its increase can actually change global mean temperature by about 0.4 centigrade ( between solar minimum and maximum).
The global average temperature is close to reaching 1.5°C above pre-industrial levels, a critical threshold for climate change impacts. This situation is exacerbated by the increasing solar activity in the current solar cycle 25, which affects the Earth's atmosphere and weather. Some scientists argue that the solar cycle will soon enter a period of low activity, but the observed and predicted data do not support this claim. According to NOAA, the solar maximum is expected to occur in 2024, not 2025, and with a higher level of sunspots and flares than previously estimated.
During very low Solar Activity known as Maunder Minimum , a period of significantly reduced solar activity from 1645 to 1710. the total solar irradiance decreased by 0.22%, leading to a drop in the average terrestrial temperature in the northern hemisphere by 1.0 – 1.5 °C (1.8 – 2.7 °F). That was five cycles in raw so if it would be one cycle would make 0.3 centigrade change. The same value change should be expected between Solar Minimum and Maximum, This resulted in frozen rivers, and colder winters and summers1.Additional facts:
Birds, fish, and sea life across the world have been dying in huge numbers over the last 2 years. Over 100,000 drum fish washed ashore in Arkansas; other sea life also are littering our shores; thousands of birds have fallen from the skies all over the world. Why? Arguably, increased solar activity coupled with a hole in the earth’s magnetosphere could be the cause. Current scientific knowledge informs us that birds and fish use the earth’s magnetic field during migrations. The magnetosphere is the area around a planet in which that planet’s magnetic force is the dominant pressure. Earth is protected from the majority of solar radiation and storms by its magnetosphere, but not entirely. (Written by watchers.news)
Solar phenomena
A solar flare is a sudden, rapid, and intense variation in brightness that occurs when magnetic energy that has built up in the solar atmosphere is suddenly released. This release of energy emits radiation across virtually the entire electromagnetic spectrum, from radio waves to x-rays and gamma rays. The energy released during a flare is typically on the order of 10^27 ergs per second, which is ten million times greater than the energy released from a volcanic explosion, but less than one-tenth of the total energy emitted by the Sun every second. There are typically three stages to a solar flare:1
Precursor stage: The release of magnetic energy is triggered, and soft x-ray emission is detected.
Impulsive stage: Protons and electrons are accelerated to energies exceeding 1 MeV, and radio waves, hard x-rays, and gamma rays are emitted.
Decay stage: There is a gradual build-up and decay of soft x-rays.
