The Earth's climate is shifting to a period of colder temperatures that could last for decades, said John Casey, president of Space and Science Research Corporation.
Casey told
Newsmax TV's "America's Forum" the change was due to the sun's energy output and a "solar hibernation" that takes place "around every 206 years."

"(The) fundamental cause is a shift in the sun's energy output. In the past, roughly (every) 200 years we've had a warming, heating up sun. By all the means that we measure sun's activity, it has reached peak levels, or at least it did some years ago. That peak was passed.
"We're now heading on the downside, where the sun's energy output is dropping rapidly. And, every time that happens, we have a deep cold climate era that can last for decades," Casey said Thursday.
During the period of cold, Casey said history recorded that "the cold is so bad we have global crop damage as a result, that leads to many other kinds of difficulties, civil strife, political upheaval."
Casey is the author of
"Dark Winter: How the Sun Is Causing a 30-Year Cold Spell", which details how the Earth's colder climate could spark political and economic upheaval.
