Detailed explanation-1: -True. Global warming is basically a gradual increase in the average temperature of the earth’s lower atmosphere.

Detailed explanation-2: -Global Warming is the gradual increase in the overall temperature of the Earth’s atmosphere. It begins with a phenomenon called the greenhouse effect. The greenhouse effect occurs when there is an interaction between Earth’s atmosphere and the radiation from the sun.

Detailed explanation-3: -Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change which is permanently changing the Earth’s climate.

Detailed explanation-4: -Global average surface temperature has risen at an average rate of 0.17°F per decade since 1901 (see Figure 2), similar to the rate of warming within the contiguous 48 states. Since the late 1970s, however, the United States has warmed faster than the global rate.

Detailed explanation-5: -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."
