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.

Highlights

One of the most important problems faced by humanity is the search of the physical mechanism responsible for global climate changes
Clouds growth simultaneously leads both to the deficit in the average annual energy budget of the planet, by increasing the reflection of incoming solar radiation back to space and to, a surplus energy budget due to the growth of the absorbed and reflected parts of the thermal radiation of the surface and the solar radiation reflected from the Earth's surface; the greenhouse effect strengthens significantly
Such additional oppositely directed an influence a growth of clouds on the change in the total balance of the average annual energy budget of the planet is extremely important for reliable identification of the role and degree of possible influence of the growth of cosmic ray flux in the lower atmosphere on the global climate variation

Summary

Introduction

One of the most important problems faced by humanity is the search of the physical mechanism responsible for global climate changes. Despite the indefinite degree of influence of cosmic rays on the cloud cover area, on the balance of the average annual energy budget of the Earth, and on subsequent cooling of the climate (Sloan & Wofendale, 2008, 2011; Erlykin et al, 2013), for the first time we will try to evaluate other unexplored and oppositely directed aspects of the energetical impact of cloud growth on the climate.
