The sun has more effect on the earth’s weather than any other factor. The lack of sunspot activity is the reason many climatologists are calling for global cooling rather than global warming. Thus, the science of global warming is far from ‘settled’ but proponents are stubbornly hanging on to it with a religious fervor that ignores evidence;
In the current study published in 3 peer-reviewed papers the researchers analysed a total background magnetic field from full disk magnetograms for three cycles of solar activity (21-23) by applying the so-called “principal component analysis”, which allows to reduce the data dimensionality and noise and to identify waves with the largest contribution to the observational data. This method can be compared with the decomposition of white light on the rainbow prism detecting the waves of different frequencies.
As a result, the researchers developed a new method of analysis, which helped to uncover that the magnetic waves in the Sun are generated in pairs, with the main pair covering 40% of the variance of the data (Zharkova et al, 2012, MNRAS). The principal component pair is responsible for the variations of a dipole field of the Sun, which is changing its polarity from pole to pole during 11-year solar sunspot activity.
For two decades, Svensmark, of the Danish National Space Institute (DTU Space) at the Technical University of Denmark, has propounded a theory of “cosmoclimatology”, which holds that cosmic rays and sunspots are the real drivers of climate change.
Atmospheric ions, produced by the energetic cosmic rays raining down through the atmosphere, helps the growth and formation of cloud condensation nuclei -- the seeds necessary for forming clouds in the atmosphere. When the ionization in the atmosphere changes, the number of cloud condensation nuclei changes affecting the properties of clouds. More cloud condensation nuclei mean more clouds and a colder climate, and vice versa. Since clouds are essential for the amount of Solar energy reaching the surface of Earth the implications can be significant for our understanding of why climate has varied in the past and also for future climate changes.
The Comic Rays
• Cosmic rays, high-energy particles raining down from exploded stars, knock electrons out of air molecules. This produces ions, that is, positive and negative molecules in the atmosphere.
• The ions help aerosols – clusters of mainly sulphuric acid and water molecules – to form and become stable against evaporation. This process is called nucleation. The small aerosols need to grow nearly a million times in mass in order to have an effect on clouds.
• The second role of ions is that they accelerate the growth of the small aerosols into cloud condensation nuclei – seeds on which liquid water droplets form to make clouds. The more ions the more aerosols become cloud condensation nuclei. It is this second property of ions which is the new result published in Nature Communications.
• Low clouds made with liquid water droplets cool the Earth’s surface.
• Variations in the Sun’s magnetic activity alter the influx of cosmic rays to the Earth.
• When the Sun is active, fewer cosmic rays reach the Earth and, with fewer low clouds, the world warms up and ended in 1998.
• When the Sun is lazy, magnetically speaking, there are more cosmic rays and more low clouds, and the world is cooler.
• The implications of the study suggest that the mechanism can have affected:
• The climate changes observed during the 20th century
• The cooling and warmings of around 2°C that has occurred repeatedly over the past 10,000 years, as the Sun’s activity and the cosmic ray influx have varied.
• The much larger variations of up to 10°C occurring as the Sun and Earth travel through the Galaxy visiting regions with varying numbers of exploding stars.
Earth Cloud Cover
Large solar eruptions decrease Earth's cloud cover, and clouds are known to affect global temperatures. The Sun’s energy output and the Total Solar Irradiance (TSI) do affect our planet's weather in repeating cycles.
Sunspot activity waxes and wanes with roughly an 11-year cycle, and through +/- 400 years of sunspot observation, it seems we are starting to repeat a cold period. The Sun influences the climate by altering the intensity of the cosmic-ray flux reaching the Earth’s surface:
➡ DURING THE SOLAR MAXIMUM When the sun is more active–more sunspots, a stronger magnetic field, larger auroras, stronger solar winds, etc.–fewer cosmic rays strike the earth and cloud cover is reduced, resulting in warmer temperatures.
➡ DURING THE SOLAR MINIMUM Fewer sunspots, Earth’s magnetic field is weakening setting into motion a chain of events which causes destabilizing of Earth’s fluids – mostly of magma and also oceans and ice.
These natural cyclical events cause the shifting of weather patterns, climate, elevated earth changing events such as earthquakes, volcanoes, tornadoes, hurricanes etc.
The sun is not subtle at all keeping all life possible down here on planet earth. The sun, when aroused puts out a higher velocity of solar wind that protects the earth from cosmic rays.
During periods of low solar activity, which we are now experiencing, the solar winds decrease allowing more cosmic rays to penetrate the earth atmosphere, which increases cloud formation, which would be the main cooling mechanism from the diminished solar activity.
Cosmic rays doubled in strength during the 20th century
When the Sun is active, its magnetic field is better at shielding us against the cosmic rays coming from outer space, before they reach our planet. By regulating the Earth’s cloud cover, the Sun can turn the temperature up and down. ... As the Sun’s magnetism increased from the Maunder Minimum to 1998, this natural mechanism may be responsible for a large part of global warming seen then. - (Henrik Svensmark)
