It is reported that the global temperature has been rising continuously for more than 150 years due to the massive emission of greenhouse gases by human beings. However, compared with 1970-1998, the rise rate of the global surface average temperature has slowed down significantly since 1999, and the rise rate of the average temperature has not been obvious in the past 15 years, so the global warming is not so serious.
 Natural disasters caused by climate warming have occurred in recent years weakens the above argument most.
