Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is global warming?
A
the steady rise of earth’s daily temperature
B
the rapid rise of Earth’s average temperature
C
the steady rise of the United States’ daily temperature
D
the rapid rise of the United States’ average temperature
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Global warming is the long-term heating of Earth’s surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. This term is not interchangeable with the term “climate change."

Detailed explanation-3: -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-4: -Global warming is the phenomenon of gradual increase in the average temperature of earth . It is caused by the release of greenhouse gases like carbon dioxide, methane, CFCs etc. into the atmosphere.

Detailed explanation-5: -Global warming is the long-term rise in the average temperature of the Earth’s climate system. It is a major aspect of climate change and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming.
