PMV indicators are the most commonly used method for thermal comfort assessment and are the method of predicting the average of many people's expression of opinion on the thermal sensory scale. The method was

Global warming
Global warming is the observed increase in the average temperature of the Earth`s atmosphere and oceans in recent decades. The Earth`s average near-surface atmospheric temperature rose 0.6 ± 0.2 degrees Celsius (1.1 ± 0.4 degrees Fahrenheit) in the 20th century.

Then, what problems are the earth undergoing because of us? Most of all, atmosphere problems are most serious. There are two atmosphere problems.
One is global warming. Global warming is the phenomenon that the average temperature of the earth's surface rises. The activities of mankind have seri
