Cosmic Rays and Clouds Variations Effect on the Climate is Insignificantly

Abstract

It is believed that an increase in the area of the cloud cover in the lower atmosphere of the Earth caused by the influence grows of galactic cosmic rays in the period of the Grand minimum of solar activity lead to an increase the reflected part of incoming solar radiation back into space and by that to a cooling of the climate down to the Little Ice Age. We will try to estimate an inverse aspect of simultaneously influence of increase in the area of the cloud cover in to the narrowing of the transmission of the windows of atmospheric transparency, which practically compensates of this cooling by means of accumulation of energy. An increase in the reflection of the thermal radiation of the Earth surface and of the solar radiation reflected from it, as well as the significant amplification of the greenhouse effect, presents an important additional source of heating due to the increase in the area of the cloud cover in the lower atmosphere. The impact of the increase in the area of the cloud cover caused by the influence grows of cosmic rays on the climate is very small.

Energy Imbalance Between the Earth and Space Controls the Climate

“…An impact of the long-term growth in the cloud coverage (presumably caused by an influence of an increase in the cosmic ray flux) on variations in the annual average energy budget of the Earth and, consequently, on the climate is virtually nonexistent. The Earth's climate does not depend on variations in cosmic rays and cloud coverage; it is defined solely by the long-term change in the energy imbalance between the Earth and outer space, as well as multiple subsequent feedback effects [24,25].…”

“…Abdussamatov [24,25] impact assessment was carried out of all aspects of possible long-term 2% growth of the cloud cover area in the lower atmosphere on the average annual energy balance of the Earth Е. An increase in the cloud cover area in the lower atmosphere will result simultaneously both in the decrease and in the increase in the temperature, which will virtually compensate each other, while the energy balance of the Earth E before and after the increase in the cloud coverage by 2% will stay essentially the same: E 1 -E о ≈ 0.…”
