Is the Sun affects our climate?

The Earth is at a distance of 150 million kilometres
from the Sun and still the radiation emitted by the Sun drives the
Earth’s climate system. Variations in the composition and
intensity of incident solar radiation hitting the Earth may
produce changes in global and regional climate which are both
different and additional to those from man-made climate change.
In the current epoch, solar variation impacts on regional climate
appear to be quite significant. Annual or decadal variations in
solar activity are correlated with sunspot activity. Sunspot
numbers have been observed and recorded over hundreds of
years. From a global perspective the processes through which
changes in incident solar radiation affect the temperature of the
Earth’s atmosphere, and the climate at the surface, are fairly
understood. The response of climate on regional scales to changes
in the composition and intensity of incident solar radiation is
more complex. Understanding the role of variability in solar
activity is essential for the interpretation of past climate and
prediction of the future. An effort is made to understand the
change in atmospheric conditions through boundary studies of
all the meteorological parameters with incoming solar radiation
and outgoing long wave radiation.
