NASA Data: Earth Cooled by Half a Degree Celsius From '16-'18

The average global temperature dropped by more than half a degree Celsius from February 2016 to February 2018, according to recent NASA data.

According to RealClear Markets, the average temperature around the world fell 0.56 degrees Celsius during that time period, the biggest dip in temperatures since a decrease of 0.47 degrees Celsius from 1982-1984.

The data came from the NASA Goddard Institute for Space Studies.

The overall temperature change during the recent two-year period was the result of two shorter changes, from February to June 2016, which turned in the largest five month drop in history, and February to June 2017.

There were several claims in 2013 and 2014 the Earth was entering a global cooling period, which was predicted to last until the middle of the current century.

A former space shuttle engineer and NASA consultant even released a book in 2014 that predicted the world was being struck by a 30-year cold spell.
