n a world riddled with climate-change doomsday predictions, a small but growing number of scientists are saying the highly touted climate models predicting steadily increasing global temperature due to humans' carbon-dioxide emissions are wrong and that Earth could soon face something even more dire: global cooling.

One such climate scientist is Valentina Zharkova, an astrophysicist at Northumbria University in the United Kingdom. Zharkova and her team of researchers say that based on mathematical models of the Sun's magnetic activity, it's likely Earth will experience decreasing magnetic waves over a 33-year period beginning in 2021.

Zharkova is not alone. In 2017, researchers at the Physical Meteorological Observatory Davos, the Swiss Federal Institute of Aquatic Science and Technology, ETH Zurich, and the University of Bern published a model projecting a cooling period "in 50 to 100 years' time."
