The rapid average rise in planet's temperature is termed as global warming.
Debate is that, global is a reality or just a myth? About 97% of scientists believe that global warming is real. People who believe that global warming is just a myth most probably say that the temperature changes with time and it is natural phenomena. Here a question rises that if it is a natural phenomena so why it is so rapid? Why Earth's average temperature is increasing so dramatically?
HISTORY:
Industrial revolution began in 1760 - 1840 and global warming was first observed between 1850 - 1900. The concentration of major greenhouse gas, Carbon Dioxide (CO2) was about 280ppm or less. Now, it has crossed 420ppm. This can't be natural.
STATISTICS:
Let compare the rise in CO2 concentration rise with rise in Earth's average temperature.
