Answer:
False
Explanation:
According to some researchers the temperature of earth has been varying since ages but the change have taken place at a very slow rate. The changing climate of earth is due to the geophysical changes that have been occurring since long and require million of years to make any substantial change. These external forces have previously modulated the temperature of earth from being extremely hot to normal habitable temperature and then to freezing cold temperature during the ice age and now again the earth has habitable temperature nut all these changes have occurred in long course of time.
Hence, the given statement is false.
