Sun will be 7 % cooler by 2050 ' research

According to the study, titled Ultraviolet Flux Decrease Under a Grand Minimum from IUE Short-wavelength Observation of Solar Analogs and published in the journal Astrophysical Journal Letters, this grand minimum will be 7 percent cooler than such periods from the past.

Essentially, the sun has a core that is like a heart that races at some times and rests at others, and at its high point the sun's core forces more magnetic loops to throw out more radiation and generate more sunspots.

The University of California, San Diego's scientists have calculated the time for suns 11-year solar cycle and predicted the next "grand-minimum" is just decades away which will leave us in a mini ice age condition. He is also trying to figure out exactly when it is likely to take place. The researchers believe that they figured out when the next solar minimum could occur. You might think "what's the big deal", but remember that this means the solar activities that create the heat of the Sun to sustain life on Earth may diminish.

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.

As per scientists, a "significant probability" is of a grand minimum quite soon, as the sunspot patterns suggest this.

"Now we have a benchmark from which we can perform better climate model simulations", Lubin said.

As the sun will get dimmer the first immediate effect on Earth will be that the ozone layer will get thinner. 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.

However, the cooling is not uniform around the globe. Although England and parts of Europe experienced unusual freezing such as the Thames River and the Baltic Sea turning to ice, other areas such as Alaska and Greenland actually had warmer temperatures. The "Maunder Minimum" occurred, as it is known, occurred in between 1645 and 1715.

Will this stop the damaging effects of global warming?

One such study looked at the climate consequences of a future Maunder Minimum-type grand solar minimum, assuming a total solar irradiance reduced by 0.25 percent over a 50-year period from 2020 to 2070.

Furthermore relating to reducing global warming scientists believe, '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'. While the help of grand minimum is appreciated and gives humanity a lot of help, it does not stop global warming.
