Mini ace age will be brought upon the Earth because the Sun will enter a 30-year-cycle of extreme cold.
NASA scientist John Casey concluded that world food supplies will be reduced by 50% and many people will die due to extremely cold temperatures.
In addition to this, there will be a number of volcanic eruptions across the globe.
Climatologist John L. Casey published a book which deals with this matter. This book is titled Dark Winter: How the Sun Is Causing a 30-Year Cold Spell. He explained in his book that the Earth is actually cooling and such weather will stay for decades.
The rapid cooling of the Earth is caused by a reduced solar activity. Casey believes that we may experience the same weather conditions which happened in the late 1700s and early 1800s, when a phenomenon called solar minimum happened.
He expects the scientific community and political leaders to act upon this in order to find a way to overcome possible cold temperatures and food shortages.
He said that there are a lot of facts which support his statement that the Earth is cooling down. Based on the 100-year global temperature chart, a steep decline in temperature has been present since 2007.
