Detailed explanation-1: -Greenhouse gases in the atmosphere, including water vapour, carbon dioxide, methane, and nitrous oxide, act to make the surface much warmer than this because they absorb and emit heat energy in all directions (including downwards), keeping Earth’s surface and lower atmosphere warm [Figure B1].
Detailed explanation-2: -Greenhouse gases are responsible for global warming because they trap heat that would otherwise escape from the atmosphere. Unlike oxygen and nitrogen, these gases can absorb radiation and hold onto heat. Greenhouse gases keep Earth at a temperature that can harbor life.
Detailed explanation-3: -Greenhouse gases have far-ranging environmental and health effects. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
