A few scientist suppose another reason occuring global warming

The earth is getting hotter day by day. As a result it is making many problems. For example, on Auguest, 2003 a number of people who were died by scorching heat wave including ,especailly, france which got lost 14,000 of citizens was 19,000 in EU. And we can often hear from some communications that the huge iceberg of the North Pole have been extremely melting . Also, it wasn't snowing as much as before in this winter in EU. It means that they had an ahnormally warm winter this year after passing 1300 years. Almost reseachers and scientists assume that the cause of global warming is carbondioxide that was maden by man as a result of economic activity. But a few of them say it has other reasons. If every causes of global warming comes from a human being, we can protect the earth from global warming. In the other hand, if it has other causes that we can not do anything for it, it's important to know what the principles and the reasons occur global warming.
Most meteorologists insist that the earth is getting hottor because of global warming and the main factor occuring global warming is the economic act of people as emiting carbondioxide. And recently El Goer who was former vice president released a dacumentary, Inconvenient Truth, which shows environmental disasters of the world by the carbondioxide . By the way, there is another theory that is contrary to the theory already mentioned in the front. Even though just few scholars insist this theory it has fairly persuasive power. A science magazine maden by USE introduced " The Milky Way Galaxy’s Spiral Arms and Ice-Age Epochs and the Cosmic Ray Connection" which was written by professor Nir J. Shaviv and professor Jan Veizer on auguest 2003. The research said the change of Cosmic Rays resulted in the change of climate because Cosmic Rays produce ion in the air and the change of Cosmic Rays is influenced by cloud layers. Cosmic Rays is corpuscles, radioactive rays, and so on coming from the universe to the earth. If this Cosmic Rays is getting more, it lowers altitude of cloud as occuring ionization much more when Cosmic Rays get to the troposphere of earth. Consequently, it brings effect which
