Over the last few weeks the solar activity has been very minimal and based on the observations made over past 100 years, Sun’s brightness has dimmed down over past few weeks.

The scientists watching the events closely as many of them believe this could be sign of next little ice age.The last time the little ice age occurres was between 1300-1850 ensuring heavy cold spells in Europe and North America.

The coldest period of the Little Ice Age, between 1645 and 1715, has been linked to a deep dip in solar storms known as the Maunder Minimum. And Scientists believe we could be in one of this period.

Scientists say the Maunder Minimum can be tracked based on the number of Sun spots visible. Sun Spots (dark spots in Sun) are caused by violent storms and usually they follow a 11 year cycle of High activity and a lull. The last lull was in 2008 and this year Sun should have started showing more activity. But It has become even quieter.

But many argue the effects of this cool period wont be felt due to Global warming. Lets wait and watch.
