Detailed explanation-1: -greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect. Carbon dioxide, methane, and water vapour are the most important greenhouse gases.
Detailed explanation-2: -Global Warming Potential (100-year): 1 Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2020, CO2 accounted for about 79% of all U.S. greenhouse gas emissions from human activities.
Detailed explanation-3: -Water vapor, carbon dioxide, methane, and other trace gases in Earth’s atmosphere absorb the longer wavelengths of outgoing infrared radiation from Earth’s surface. These gases then emit the infrared radiation in all directions, both outward toward space and downward toward Earth.
Detailed explanation-4: -This ability to absorb and re-emit infrared energy is what makes CO2 an effective heat-trapping greenhouse gas.
Detailed explanation-5: -Greenhouse gases that occur both naturally and from human activities include water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone (O3).
