New Delhi : Data collected from 20 years of observations, the researchers have calculated that sun will lose seven per cent of heat by 2050 that may result in bringing mini ice age on Earth.

Researchers from University of California in San Diego claim that they have figured out a process to calculate 11 year cycle of sun.

During the cycle sun's temperature keeps on changing with uniformity and researchers say with the newly found method they know when will the sun will have solar minimum.

When sun experiences solar minimum, ultraviolet rays emission also decreases significantly. During the course, Sun becomes clearer but dimmer.

As mentioned in the study, the solar minimum period, labelled as a "grand minimum", could be similar to the one Earth had experienced in in the middle of the 17th century. River Thames had frozen due to minimum temperature.

With mini ice age type conditions, the head of the research team, Dan Lubin, believes we may experience even worse conditions in 2050.

The study said that when the sun’s energy is reduced, the first thing that occurs is the thinning of the stratospheric ozone layer.

"That thinning in turn changes the temperature structure of the stratosphere, which then changes the dynamics of the lower atmosphere, especially wind and weather patterns," it noted.

It may help Earth in decreasing ice melting in future but the negative aspects remains constant with climate change as the process will just get slow and not stop.

“The cooling effect of a grand minimum is only a fraction of the warming effect caused by the increasing concentration of carbon dioxide in the atmosphere,” the study said.
