Detailed explanation-1: -As the level of these gases rises, so does the temperature of Earth. The rise in Earth’s average temperature contributed to by human activity is known as global warming.

Detailed explanation-2: -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-3: -Greenhouse Gases Carbon dioxide, methane, and nitrous oxide concentrations are now more abundant in the earth’s atmosphere than any time in the last 800, 000 years. These greenhouse gas emissions have increased the greenhouse effect and caused the earth’s surface temperature to rise.

Detailed explanation-4: -The increase in greenhouse gases from the burning of fossil fuels, agricultural activities, and deforestation, which has caused global average air temperatures to increase.

Detailed explanation-5: -an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect.
