Abstract:
There are some evidences that support global climatic change by cosmic rays and ionosphere-ground electrical circuit variations; in turn these variations are strongly linked to storms sudden commencement. Here we define the SSC index as the product of the amplitude by the duration time of each storm sudden commencement. A wavelet multi-resolution analysis of yearly means of global temperature, radiative input and SSC index time series since 1868 is performed. It is found that for time scales larger than 60 years a 70 % of the long-term NH change in earth surface temperature might be attributed to SSC index and the remainder 30 % to solar irradiance. This finding is discussed in the light of long-term evolution of solar magnetic dynamo field and related parameters. In particular it is shown that the long-term surface temperature variation has its maximum value around 1995 and monotonically decreases afterward. This tendency could be maintained for the forthcoming years following the descending chaotic transition that solar dynamo system started around 1993.
