Detailed explanation-1: -Earth’s temperature has risen by an average of 0.14° Fahrenheit (0.08° Celsius) per decade since 1880, or about 2° F in total. The rate of warming since 1981 is more than twice as fast: 0.32° F (0.18° C) per decade.
Detailed explanation-2: -Over the last century, the average surface temperature of the Earth has increased by about 1.0o F. The eleven warmest years this century have all occurred since 1980, with 1995 the warmest on record.
Detailed explanation-3: -According to an ongoing temperature analysis led by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by at least 1.1° Celsius (1.9° Fahrenheit) since 1880.
Detailed explanation-4: -Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.
