Most scientists believe that the current global warming is caused by human emissions of greenhouse gases and that the most important of these gases is the carbon dioxide or CO2.
They also believe that the Sun's influence for this warming is very small. Now we know that the irradiance or "transfer heat "between the Sun and the Earth has changed relatively little over the last decades. Therefore the conclusion that most scientists have made resentment is that heating must be done by man, is because they have not found any reasonable explanation.
But what we know about the quantity of a specific increase of CO2 on global temperature is poor. The reason that knowledge of how greenhouse gases affect cloud formation is mainly to down to speculation. the physics of cloud formation is a rather complicated to explain to many factors.
So instead of having a solid theoretical basis and is measured by how much the man of greenhouse gases affect the climate, the estimate is mainly down to the deduction.
They argue: We know how much the temperature has risen so therefore we can calculate the amount of a given increase in greenhouse gases will increase global temperatures in the future. We have done through discounts as we have attributed the increase is known greenhouse driven.
But scientists studying the sun since long noted the similarities between solar activity and terrestrial weather patterns.
Also, changes in the climate of the last century is not unique. Given the small relative changes in the observed irradiance "heat emitted by the Sun", changes in temperature during the past centuries are hard to explain if there are other types of influence of the sun.
It was not until the Danish scientist Henrik Svensmark suggested that cosmic radiation may influence cloud cover that is explained by a plausible this apparent correlation was given.
Here is this theory!
When the sun is very active, as now, the solar wind and the solar magnetic field are both strong. This in turn protects the earth from high energy particles from the cosmos, usually from particles which are created once in supernova explosions. This affects the formation of low cloud cover that radiation create ions which form seed cloud droplets. During times when there are many high-energy particles reaching low altitudes there is lower cloud cover and the Earth cools. When there are few high energy penetrating at low altitudes and fewer clouds form and the Earth warms.
In general, high clouds in the atmosphere are usually ionic low and high energy particles because both types of particles penetrate high altitudes at all times.
Variations are created only on the cover low-lying cloud that is affected by high energy cosmic particles.
Recently, an experiment called SKY (Cloud in Danish) was made by Svensmark which conclusively confirmed this cloud forming mechanism experimentally and that this type of cosmic ionization has an important effect of seeds in the clouds. Links between low cloud cover variations and high energy particles intensity have also been confirmed by satellite studies.
