GEOLOGY

Detailed explanation-1: -With more greenhouse gases in the air, heat passing through on its way out of the atmosphere is more likely to be stopped. The added greenhouse gases absorb the heat.

Detailed explanation-2: -Greenhouse gases The greenhouse effect: some of the infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. The effect of this is to warm the Earth’s surface and the lower atmosphere.

Detailed explanation-3: -NASA has observed increases in the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth’s atmosphere to trap more and more heat. This causes Earth to warm up.

Detailed explanation-4: -Because air pollution and greenhouse gases are often released from the same sources, cutting greenhouse gas emissions in an effort to slow climate change also reduces air pollutants, such as fine particulate matter (PM2.5). Reducing these co-emitted air pollutants improves air quality and benefits human health.

Detailed explanation-5: -Some atmospheric gases absorb and re-emit infrared energy from the atmosphere down to the Earth’s surface. This process, the greenhouse effect, leads to a mean surface temperature that is 33 °C greater than it would be in its absence.
